DESIGNED FOR EVERYONE

Tells You a Story, Not Just Numbers

Most fitness apps dump raw data at you and expect you to figure it out. KritFit speaks plain English. Instead of "Net remaining: +3450 kcal" you see: "Your body used 3917 kcal today and you ate 227 kcal — that's a very large deficit. Make sure you're eating enough nutrients." Weight trends say "Down 1.2kg in 14 days — good momentum" not just an arrow. Supplements say "Perfect week — every day ✓" not "7/7 doses". You don't need a fitness degree to understand your own body.

Plain English Context-Aware No Fitness Degree Required

THE RELATIONSHIP THAT MAKES KRITFIT UNIQUE

Many Trainers. Many Clients.
One App. Zero Limits.

KritFit is built around a relationship no other fitness app supports: a trainer can work with an unlimited number of clients — and a client can work with multiple trainers at the same time. Strength coach. Nutritionist. Running coach. All connected. All in one app.

ONE TRAINER

🏋️

Manages Multiple Clients

▸ View any client's full app with one tap

▸ Send proposals: food, exercise, weight, routines

▸ Message one client or broadcast to all

▸ Log sessions on a client's behalf

▸ Colour-coded so you never confuse whose data you're in

⇆

MUTUAL
CONSENT

ONE CLIENT

🏃

Works With Multiple Trainers

▸ Connect to unlimited trainers simultaneously

▸ Assign each trainer a personal tag (initial or emoji)

▸ Every accepted item is stamped with the trainer's tag

▸ Conflict detection if two trainers propose the same thing

▸ Pause or end any connection without affecting others

No Other Free Fitness App Supports This.

Competing apps treat the trainer-client relationship as one-to-one and one-at-a-time. KritFit's architecture supports many-to-many connections — a personal trainer with 20 clients, each of whom also has a nutritionist, a running coach, and a physio — all in the same app, all working from the same data, with full conflict detection and data attribution built in.

📋 PROPOSAL SYSTEM

Trainers send proposals for food entries, exercise sessions, weight targets and full workout routines. Clients see a pending proposals section with Accept / Reject on each item. One Accept tap writes the data directly to their log, tagged with the trainer's label.

🏷 TRAINER TAGS

Each trainer gets a tag — JD, 💪, NM — assigned by the client. Every entry that came from a trainer proposal shows a small coloured pill in the food, exercise and weight logs. Clients always know what was trainer-prescribed. Trainers can't see each other's tags.

⚠️ CONFLICT DETECTION

When two trainers send overlapping proposals — same food, same exercise, same date — KritFit flags the conflict. A combined summary header shows total proposed calories and burn across all pending plans. First accepted wins. Or the client can choose to Replace a previously accepted entry.

📶 Works Fully Offline — Unlike Most Fitness Apps

Many gyms have unreliable WiFi — and connecting to a stranger's network is a security risk nobody should have to take just to log a workout. KritFit doesn't need any of it. Log food, exercise, weight — everything — with zero internet connection. Your data saves locally on your device and syncs automatically the instant you reconnect on your own network. At the gym, on a trail, in a basement — it works everywhere, every time. No lost entries. No errors. No security compromises.

💾

LOCAL-FIRST DATA

All your data lives on your device first — Firebase is a backup, not a requirement. Log anywhere.

🔄

AUTO-SYNC ON RECONNECT

Come back online and everything syncs silently in the background. You'll never lose a log entry.

🏔

GYM, TRAIL, FLIGHT

Underground gym, mountain trail, mid-flight — KritFit works everywhere your body does.

MyFitnessPal, Cronometer, and most competing apps require a live connection to function. KritFit doesn't. It's the only fitness app with true offline support and automatic background sync — built in from the ground up, not bolted on.

🏋️ NEW FEATURE

GYM MEMBERSHIP MANAGER

One App. Every Gym. Zero Fumbling.

How many gym apps do you have on your phone right now? Planet Fitness for the QR code. Title Boxing to check the class schedule. Google Calendar — added manually. And a push reminder you set yourself and promptly forgot. KritFit replaces all of them. Add your memberships, upload your QR or ID screenshot, set your class schedule — and KritFit handles everything else automatically.

🪪 QR CODE VAULT

Screenshot your gym QR or barcode, upload it once, and it lives in KritFit. One tap from your lock screen puts it full-screen at maximum brightness — exactly what the scanner needs. No hunting through apps.

📅 CLASS SCHEDULING

Set your recurring class days — Mon, Wed, Fri at 6:30pm — and KritFit creates a repeating Google Calendar event automatically. No manual calendar entries ever again. Change it once, it updates everywhere.

🔔 SMART PUSH REMINDERS

Get a push notification 15 minutes, 1 hour, or 2 hours before your class — your choice. Tap the notification and KritFit opens directly to your membership QR code. From lock screen to scanner in one tap.

On days you have a class, KritFit surfaces a GYM TODAY card at the top of your Dashboard — gym name, class time, and a CHECK IN → button that opens your QR code instantly. Your personal trainer, your food log, your workouts, and now your gym memberships — one app, everything fitness.

🏢 GYM PLATFORM

FOR GYM OWNERS

Your Gym. Your Classes. Your Store.

KritFit isn't just for gym members — it gives gym owners a full member-management platform built directly into the app. Set your opening hours, publish your class schedule, and even run a mini storefront. Your members see everything in their personalised MEMBERSHIP portal, organised into clean tabs.

📅 CLASS SCHEDULE

Publish your weekly class timetable. Each class can have multiple time slots on the same day — morning and evening sessions in one tap. Members see today's classes the moment they open their Membership tab, with instructor names and times. No app logins, no PDFs, no printed notices.

🛍 GYM STORE

+$3.45/mo upgrade

Give members a browsable product catalogue inside KritFit — protein bars, merchandise, supplements, personal training packages. Add a photo, description and price in your local currency ($, £, €, QR — any symbol). Members browse it under the STORE tab. Not every gym needs a store — unlock it when you're ready to sell.

ℹ️ MEMBER PORTAL

Every member's MEMBERSHIP tab becomes a four-panel portal: ABOUT (gym info, opening hours), ACCOUNT (their member code, status, QR check-in), CLASSES (today's timetable + full week), and STORE (your catalogue). Tabs only appear when the content exists.

The orange header of every member's portal shows today's opening hours at a glance — Open today · 6am–10pm. Set your 7-day schedule once in ADMIN → ABOUT and every member sees it instantly. No group chats, no sticky notes, no confusion.

NO WEARABLE NEEDED

Built-In Mobile Step & Pace Tracker

Your phone already has everything it needs. KritFit taps into the built-in accelerometer to count your steps, measure cadence and estimate distance in real time — no Fitbit, no Apple Watch, no subscription. A 3-step calibration wizard learns your exact stride length and motion signature for ±5% accuracy. Sessions auto-log to your exercise history with MET-calculated calories. Walk mode. Run mode. One tap to stop and save.

⏱ NEW FEATURE

BUILT-IN STOPWATCH + GPS ROUTE RECORDER

KritFit Timer — Start, Stop, It’s Logged.

Every other fitness app makes you juggle three things at once: a timer, a GPS app, and a logging screen. KritFit Timer eliminates all of that. It’s a precision stopwatch and a GPS route recorder built directly into the exercise panel — one tap away, always visible.

⏱ STOPWATCH

Press ▶ when your session starts. Press ⏹ when you’re done. KritFit auto-fills the elapsed time into every duration field on the page — running, cycling, sports, wellness, strength. No number to remember. No field to type into.

📍 GPS TRACKER

Tap 📍 before you start. Your phone’s GPS quietly tracks every metre of your route in real time. When you stop, the distance is auto-filled into the distance field. No Garmin. No Strava. No subscription. On a treadmill or indoors? KritFit falls back to step estimation automatically.

🗺 SAVES YOUR ROUTE

When you stop with GPS active, KritFit asks if you want to save the route. Say yes — KritFit packages every GPS point, calculates distance, elevation gain and personalised calories, then renders your full route on an interactive OpenStreetMap. The Routes tab lights up with a red badge so you know it’s there.

This is what every app should do but none of them do. Every step of your session — timing it, tracking it, naming it, mapping it, logging it — happens in one place, with one tool, in one app. KritFit Timer is the missing piece between going for a run and having it properly recorded.

GENETIC PERSONALISATION

Trained by Science. Guided by Your DNA.

Most apps treat everyone the same. KritFit doesn't. Enter your genetic markers from 23andMe, AncestryDNA or any provider — and KritFit starts responding to you specifically. Select the Cardio tab and see a personalised genetic insight appear instantly. Switch to Weights and get a different one. Every tab, every session — your DNA is quietly working in the background, flagging what to prioritise and what to be careful about. Green signals tell you when you're training to your genetic strengths. Amber signals warn you when your profile suggests extra care. Five key markers are supported: ACTN3 (muscle fibre type), ACE (cardiovascular efficiency), COL1A1 (injury risk), PPARA (fat metabolism) and BDNF (recovery & adaptation). Optional, private, and genuinely useful.

RECOVERY INTELLIGENCE

Sleep Tracking — The Missing Link in Fitness

Training hard is only half the equation. Your body repairs muscle, consolidates memory and regulates hormones while you sleep. Poor sleep raises cortisol, increases appetite, kills motivation and stalls progress — no matter how good your training plan is. Yet almost no fitness apps track it. KritFit does.

Log your bedtime and wake time and KritFit instantly calculates your total sleep hours and sleep efficiency (the gold-standard metric used by sleep clinicians — actual sleep time as a percentage of time in bed). Rate your restfulness, sleep depth and stress level. Flag daytime habits — caffeine, alcohol, late exercise, screens — and note any disturbances. Every entry is stored, synced and visualised as a 7-night colour-coded bar chart on your Dashboard. Green = 7h+. Amber = 6–7h. Red = under 6h.

And then KritFit does something smarter. If you logged a poor night's sleep, the Train tab shows a personalised warning suggesting a lighter session. Good sleep? You get a positive nudge instead. High stress logged? The Food tab reminds you that cortisol drives appetite. The app reads your sleep and uses it — across every section where it matters.

🔄 NEW FEATURE

THE OTHER HALF OF TRAINING

Recovery Intelligence — Most Apps Ignore This Entirely.

Here’s what most fitness apps don’t tell you: training is the stimulus. Recovery is where the result actually happens. Muscle repairs during sleep, not during the set. Growth hormone peaks at 2am, not mid-squat. Cortisol from poor sleep undoes three days of clean eating in 24 hours. And yet almost every fitness app stops when the workout ends — as if the other 22 hours don’t exist. KritFit is different.

🔢 RECOVERY INDEX

A 0–100 score calculated daily from sleep quality, rest days, active recovery logged, supplements taken and consecutive training days. When it drops, KritFit nudges you. When you’re on top of it, it stays out of the way.

📋 RECOVERY LOG

Log active recovery (yoga, foam rolling, swimming), passive recovery (sauna, cold plunge, massage) or mental recovery (meditation, box breathing, journaling). Rate how you felt before and after. Build a real picture of what works for you.

📖 RECOVERY GUIDE

Seven evidence-based articles inside the app: sleep physiology, active recovery, heat therapy, cold therapy, post-workout nutrition, mental recovery, and recovery supplements. Not generic advice — referenced science, written to be actionable.

The app watches for consecutive training days. Hit three or more and a gentle nudge appears on your Dashboard — a reminder that the best thing you can do for tomorrow’s session is recover properly today. Not a nag. Not a forced rest day. Just the information, delivered when it’s relevant. This is what separates a fitness intelligence platform from a calorie counter.

BODY COMPOSITION

Skinfold Calipers & Body Fat Tracking

The scale only tells half the story. KritFit supports full skinfold caliper measurements across seven sites — chest, abdomen, thigh, tricep, subscapular, suprailiac and midaxillary. Body fat percentage is calculated using the Jackson-Pollock 3-site formula, adjusted for biological sex, giving you a genuinely accurate picture of your body composition over time. Results are logged with a date stamp so you can track real fat loss — not just weight loss. A tool previously only found in professional gym assessments, now in your pocket for free.

EXCLUSIVE TO KRITFIT

Music Made for the Work

Most people shuffle a random playlist while they train. KritFit goes further — original tracks written and produced specifically for each exercise category. Every lyric is matched to the workout. Cardio tracks keep your pace up. Weights tracks keep your focus locked. Wellness tracks bring you down gently. Not a playlist. Not a radio station. Music that knows what you're doing. Available in the app under the 🎧 Music tab — one tap, loops for your entire session.

CALISTHENICS — SETS & REPS

💪 Bodyweight Training, Tracked Properly

Most fitness apps log push-ups as "12 minutes, moderate intensity." KritFit logs them the way athletes actually think — 4 sets × 20 reps. Tap any calisthenics exercise, enter your sets and reps, and KritFit calculates calories burned using research-validated per-rep values from the Compendium of Physical Activities, scaled to your actual body weight. The heavier you are, the more you burn per rep — and KritFit accounts for that automatically.

INBOX — MESSAGING, GROUPS & COMMUNITY

Your Gym Crew. One Thread. Always In The App.

Fitness happens in community. Your workout partner keeps you accountable. Your Thursday class has a group chat. Your running crew shares routes. Your trainer messages you between sessions. Until now you had WhatsApp for the crew, email for the trainer, and a fitness app for everything else. KritFit collapses all of it into one place. Friend threads. Group chats. Trainer conversations. All inside the app, all with push notifications, all synced in real time across every device.

👥 GROUP CHATS

Any KritFit user can create a group — pick an emoji icon, set the name, add members from your friends list or by email. WhatsApp-style threads. Send a message and every member gets it instantly, with a push notification if they're offline. Mute without leaving. Leave when you want. Your gym crew, your Thursday class, your running group — all in one tab.

✉️ FRIEND THREADS

Add any KritFit user by their registered email. Send a request — they get a green banner notification immediately. Accept, reject or block. Full one-to-one WhatsApp-style threads: real-time delivery, ✓✓ read receipts, reply-threading, message deletion. Share your progress with KritFit Cards — Day Summary, Workout, Food Log, Weight Update, Personal Best or Progress Photo — formatted beautifully inside the thread.

🔔 LIVE PUSH & IN-APP BANNER

Every message — friend, group, or trainer — triggers a push notification if you're offline. Open the app and you get a green sticky banner at the top with the sender's name and message preview. Tap it and you land directly in that thread. KritFit knows if you're already online and suppresses the push to avoid double-notifying. Mute any thread to stop notifications without losing the conversation.

Why this matters: Most fitness apps are solo experiences. KritFit treats fitness as social — because accountability, shared progress and community are the biggest predictors of long-term adherence. Groups aren't a chat bolt-on. They're a core feature built into the same infrastructure as the rest of the app.

Workout Routines

Build named workout routines with every exercise, set, rep and weight pre-defined. KritFit pre-calculates the total calorie burn using a personalised MET formula at save time. Log a full multi-exercise session with one tap — no data entry during your workout. Trainers can build routines from their own exercise library and send them to clients as proposals. Clients get the routine and all its exercises installed in one Accept tap, with a TRAINER badge so they know it came from their coach.

WEIGHT TRACKING — CONTEXT MATTERS

⚖️ Weigh-in Conditions — Know When Your Number Is Real

A 1 kg spike overnight isn't always fat. It could be a salty meal, alcohol, poor sleep, or just not using the bathroom yet. KritFit is the only fitness tracker that records the context of every weigh-in — so you know when a number means something and when it's just noise.

NUTRITION KNOWLEDGE BASE — BUILT INTO THE FOOD TAB

Know What You're Eating.
Not Just How Many Calories.

Most fitness apps tell you how many calories you ate. None of them tell you why it matters what you ate. KritFit adds a full nutrition knowledge base — written at the level of a professional nutritionist — directly inside the food tab. Protein, carbohydrates, fat, fibre, iron, calcium, vitamin D, omega-3, gut health, glycaemic index and more. Each topic covers what it is, why your body needs it, your daily target, the best food sources, and signs of deficiency. Science-backed. Plain English.

📚 14 ARTICLES

Three categories — Macros (protein, carbs, fat, fibre), Micros (iron, calcium, vitamin D, magnesium, zinc, B12), and Topics (omega-3, sodium, hydration, gut health, glycaemic index). Filter by category or browse all. Each article expands on tap.

🔬 SCIENCE-BACKED DEPTH

Every article includes the clinical RDA, the best whole-food sources shown as quick-scan pills, signs of deficiency to watch for, and a practical warning where over-supplementation or common mistakes apply. Not a blog post — reference-grade information.

💡 PERSONALISED INSIGHTS

KritFit reads your logged food and fires a smart insight card above your daily log — "You're behind on protein today," "Heavy on simple carbs," "High sodium — expect water retention tomorrow." Each insight links directly to the relevant article. Real-time. Relevant to your actual day.

🛒 TAP A FOOD — SHOP IT

Every food source pill is shoppable. Tap Almonds and a shop panel opens below — supplements route to iHerb, fresh foods to Instacart. Select multiple items and shop them in one tap. Use your earned KritFit points for an instant discount at iHerb. The knowledge pays for itself.

Why this exists: Calorie counting is a useful tool, but it teaches you nothing about nutrition. Understanding why protein matters, why fibre is the single best predictor of a healthy diet, and why not all carbohydrates behave the same — that's the knowledge that creates lasting habits. KritFit puts that education one tap from your food log, at the exact moment it's relevant.

SUPPLEMENT TRACKING & SMART REMINDERS

💊 Take the Right Supplement. At the Right Time. Every Day.

Most people buy supplements and forget to take them. Or take them at the wrong time. Or lose track of which ones they've already taken today. KritFit solves all three. Track 32 built-in supplements across 8 categories — Protein, Creatine, Pre-Workout, Recovery, Vitamins, Performance, Weight Management and Gut Health — plus any custom supplement you add yourself. Log dose, unit, timing and notes. Green ✓ badges show what you've taken today. 7-day habit history shows your consistency at a glance.

📋 NAMED REGIMES

Group your supplements into named regimes — Morning Stack, Pre-Workout, Night Recovery. Each regime has its own set of supplements with individual doses. Set a daily, weekday, weekend or custom day-of-week schedule for each.

🔔 PUSH REMINDERS

Set a reminder time per regime. KritFit fires a push notification — even when the app is closed — listing every supplement due and its dose. Already taken them? Mark them off and the reminder stops. Already logged today? KritFit won't nag you.

📊 HABIT TRACKING

The 7-day history shows a green ✓ or empty circle for every supplement, every day. Consistency gaps are impossible to ignore. Your supplements tab also reports "Perfect week — every day ✓" in plain English, not just a fraction.

MEAL BUDGET PLANNER

🗓 Plan Your Meals. Get Reminded. Log What You Ate.

Reactive food logging — eating first, logging after — is the reason most diets fail by Wednesday. KritFit lets you plan your meals in advance: add your intended Breakfast, Lunch, Dinner and Snack items for the day with their calorie and macro estimates. That plan sits in your food tab as a visual budget. When your meal window approaches, KritFit sends a push reminder so you're never caught off-guard. At the end of the day, if you logged less than half your planned calories, a second nudge reminds you to finalise your log.

Add planned food items for each meal window — Breakfast, Lunch, Dinner, Snack. Assign calories and macros. The plan is visible in your food log for the day so you know exactly what your intake will look like before you eat.

🔔 MEAL WINDOW REMINDERS

KritFit reads your meal times from your profile. One hour before each planned meal, a push notification arrives: "Lunch is coming up — 580 kcal planned. Ready to log?" Stay on budget, stay on plan.

➡️ SEND TO LOG

Ate what you planned? One tap — Send to Log — converts all planned items into actual food log entries for the day. No re-entering. Trainers can send meal budget plans to clients as proposals, pre-loading the client's entire day with a structured eating plan.

Evening check-in: At 8pm, if your actual logged calories are less than 50% of your day plan, KritFit sends a gentle push: "You planned 2100 kcal today but only logged 680. Don't forget to Send to Log!" One nudge. Not a spam campaign.

PUSH NOTIFICATION SYSTEM

🔔 KritFit Reaches You — Even When It's Closed.

KritFit is built on Firebase Cloud Messaging — the same push infrastructure used by Google. Notifications fire from a server-side Cloud Function that runs regardless of whether your phone is in your pocket, your screen is off, or the app hasn't been opened in days. This is true push — not in-app alerts that only work when you're already looking at the screen.

💬

MESSAGES

New friend message, group message or trainer message — push fires instantly. Sender name and message preview in the notification.

👋

FRIEND REQUESTS

Someone sends you a friend request — green banner inside the app, push when you're offline. Tap to go straight to Inbox.

📋

TRAINER PROPOSALS

Your trainer sends a proposal — food plan, workout, weight target. Push fires immediately. Tap to review and accept or reject.

💊

SUPPLEMENT REMINDERS

Hourly scheduled push for each active regime. Bundles all due supplements into one notification. Smart — skips ones already logged. Respects your schedule (daily / weekdays / weekends).

🗓

MEAL REMINDERS

Pre-meal push based on your meal windows. Evening nudge if your plan is less than 50% logged. One smart notification — not spam.

🏋️

GYM CLASS REMINDERS

Push fires 15 min, 1 hour or 2 hours before your class — your choice. Tap the notification and KritFit opens directly to your membership QR code.

Smart presence detection: KritFit tracks whether you're actively using the app. If you are, push is suppressed and a green in-app banner slides down instead — with the sender's name and a TAP TO VIEW button. No double-notifying. No noise. Just the right alert in the right place.

Trainer & Client System

A full professional coaching platform inside one affordable app. Trainers manage entire client rosters — view any client's live data, log sessions, send food and exercise proposals, broadcast messages. Clients can connect with multiple trainers simultaneously — strength coach, nutritionist, running coach — with smart conflict detection when two trainers propose the same thing.

🏷 Trainer Tags — every accepted proposal is stamped with a tag so clients know exactly who prescribed what

📋 Proposals — trainers send food plans, workouts, weight targets; one Accept tap installs them

📢 Broadcast — message all active clients at once with one send

🔔 Push notifications — trainer messages and proposals fire even when the app is closed

Sports & Team Activities

Log 20 sports from football to pickleball to martial arts. Choose your sports once in Settings — they appear as quick-tap buttons. Enter duration and intensity (easy/normal/hard) and KritFit calculates calories using research-validated MET values personalised to your body weight. Intensity multipliers adjust from casual kickabout to competitive match.

GPS Routes & Live Route Recording

Two ways to get a route into KritFit. Import a GPX file from Strava, Garmin, Komoot or Apple Health. Or record live with KritFit Timer — tap 📍, go for your run, walk, Harley ride or hike, tap stop, pick your activity type and KritFit saves it automatically. Either way, KritFit calculates distance, elevation gain and personalised calories, then draws your full track on a live OpenStreetMap — always visible at the top of the Routes tab, not hidden behind a button.

Name and describe every route. Add a title and a description to each card — “Morning Park Loop” or “Clockwise via the bridge, avoid the hill on wet days”. Edit them any time.

Repeat routes get smarter over time. KritFit fingerprints each route using GPS start/end points and distance. Run the same route again and instead of creating a duplicate card, a new run entry is added to the existing one. The card shows a 3 runs badge and keeps a full history of every date, time and calorie count. You can also manually log a repeat — just tap INFO, enter the date and duration, and KritFit calculates the calories.

Physique Assessment

The PHYSIQUE tab in Body Stats goes beyond waist and bicep measurements. Enter skinfold caliper readings at up to 7 sites — KritFit calculates your body fat % live using the Jackson-Pollock 3-site formula, adjusted for sex and age. Then see your FFMI (Fat-Free Mass Index), Lean Body Mass, Fat Mass and Symmetry Ratios — the shoulder-to-waist golden ratio (1.618) used in classic physique judging. Full caliper history with trend tracking. This is the data serious competitors and coaches actually use.

Firebase Sync

Everything — your profile, food log, exercise history, plans, recipes, body measurements and goals — syncs securely to Google's Firebase, one of the world's most trusted database platforms. Your data is isolated under your unique Google account ID. No other user can ever access it. Your data follows you across all your devices.

📍

Gyms Near You

Your location is shown on the Dashboard alongside a Gyms Near Me finder. Set your search radius using a slider — in miles or kilometres based on your profile settings — and KritFit queries OpenStreetMap to show all gyms within that distance on an interactive map. Each pin shows the gym name, address and exact distance. Results are sorted closest first. No Google API key needed — completely free and private.

Instacart Delivery — Right From Food Search

Every food search in KritFit ends with a quiet but useful suggestion: get it delivered. At the bottom of your search results, a one-tap card pre-fills Instacart with whatever you just searched for — opening the store search in a new tab, ready to order. Log it, then shop it. No copy-pasting, no switching apps, no re-typing. If you tracked chicken breast, one tap takes you straight to chicken breast on Instacart. Useful when you're meal prepping, running low on an ingredient, or just want to restock what you're eating without losing your train of thought.

Weather-Smart Activity Suggestions

KritFit checks today's local forecast and recommends an activity that matches the conditions — automatically, every time you open the app. Sunny day? It'll nudge you towards your configured outdoor sport — Running, Cycling, Tennis, whatever you actually do. Raining? It switches to your indoor activities — weights session, Yoga, CrossFit or any wellness class you've set up. Suggestions are personalised to your sports and activities, not a generic list. They rotate across four phrase variants so it never feels repetitive. The forecast also appears as a compact banner inside the Train tab so it's front-and-centre when you're deciding what to do today.

TRAIN TOGETHER

KritFit is for Everyone — Including Personal Trainers

One App.
Every Client.
Zero Friction.

The Trainer Portal is $5.67/month — KritFit Advanced included. When you're ready to sell programs or bundles, add the store for just $3.45/month. Cancel either independently, any time. Either way, that same app becomes your full coaching platform — view client data live, log their sessions, message them directly, broadcast to your entire roster at once. Clients connect with multiple trainers simultaneously — strength coach, nutritionist, running coach — each tagged so they always know who prescribed what. No extra software. No separate logins. No per-client fees.

🔑

Dead Simple Onboarding

Generate your unique trainer code in one tap. Share it with a client along with your Gmail. They enter it in their app, hit send — you get a notification, tap Accept. That's it. They're in. No forms, no portals, no email chains. The whole process takes under 60 seconds.

👁

Full View. Full Control.

Switch to any client with one tap from a dropdown. Their complete app opens — food log, exercise history, weight trend, body measurements, supplements, plans. Log a session on their behalf. Set up their profile if they haven't. A permanent orange banner keeps it crystal clear whose data you're viewing. One tap back to your own data.

🛡

Client Controls. Always.

Every client keeps full ownership of their own data at all times. They can pause trainer access with one tap if they need privacy — then resume it just as easily. They can remove the connection entirely whenever they choose. Trust is built in, not bolted on. Clients never need to hand over passwords or share accounts.

👥

Trainer ↔ Client Messaging

No WhatsApp. No email threads. Trainers and clients message each other directly inside KritFit — app to app, completely private. Send to one client or broadcast to all at once. Real-time delivery, read receipts, reply threading and push notifications. A red unread badge on the CLIENTS button means there's something waiting.

📹

Video Calls With Clients

Take your sessions remote without leaving the app. Trainers and clients can video call each other directly inside KritFit — no Zoom, no FaceTime, no context-switching. Perfect for remote check-ins, form reviews, and keeping the relationship strong regardless of geography.

🏆

UNIQUE TO KRITFIT

Work With Multiple Trainers Simultaneously

No other fitness app does this. In KritFit, a client can be connected to more than one trainer at the same time — a strength coach, a running coach, a nutritionist — each working inside the same app, each seeing the same client data, each sending their own proposals. The client accepts what they want from each trainer and their data stays clean, attributed, and conflict-managed.

🏷 TRAINER TAGS

Each trainer gets a personal tag — a 1–2 character initial or emoji that the client assigns. Every piece of data accepted from a trainer's proposal is silently stamped with their tag. Your food log, your exercise log, your weight entries — each shows a small coloured pill: JD for your strength coach, 💪 for your nutritionist. You always know the origin.

⚠️ CONFLICT DETECTION

When two trainers propose the same thing — the same exercise on the same date, the same food entry, the same weigh-in — KritFit flags it. A combined header shows the total proposed calories and burn across all trainers. Conflicts are marked: first-accepted wins. The client can also choose to Replace a previously accepted entry with a newer proposal.

🔒 ALWAYS CLIENT-CONTROLLED

Each trainer connection is independent. The client can pause, resume or terminate any one connection without affecting the others. Trainer tags are only visible to the client — not to the trainers themselves. Your coaches see your data. They don't see each other's tags or know who else you're working with.

Real-world use case: You're training for a triathlon. Your strength coach sends weekly weight sessions. Your running coach sends interval plans. Your nutritionist sends meal budgets. All three arrive in the same app, on your single profile, tagged so you always know who prescribed what — and you control every Accept.

Huldufólk Habitat Project

Healing by Oregon's Great Outdoors

The Vision

Huldufólk Habitat Project

Inspired by ancient folklore and earth-integrated architecture, Huldufólk Habitat Project will strive to be a revolutionary, self-sustaining village tucked into the lush forests of Oregon. Designed to permanently home, heal, and restore individuals experiencing chronic homelessness through a multi-generational community that welcomes families, children, the elderly, and the disabled.

The village will aim to include discreet spaces for clinical substance abuse rehabilitation and trauma-informed counseling — alongside a rich, tactile atmosphere where residents and visiting eco-tourists can unplug, heal, and practice meditation.

The Balance

To ensure long-term stability and prevent an institutional feel, the population is carefully balanced.

60%

Restorative residents gaining permanent housing and rebuilding purpose within the community.

15%

Lifestyle supporters who choose to live here, providing daily mentorship and skilled guidance.

25%

Paying eco-tourists booking immersive stays to experience earth-living — their fees go directly toward the village's upkeep.

Village street scene — Wandering the village street is an experience unlike anything most tourists have ever encountered — a fully inhabited forest settlement of curved earthen walls, living roofs, and lantern-lit paths. People come to walk, breathe, and remember what it feels like to be part of the earth rather than apart from it.

Tourist studio layout — Earthen homes are deeply therapeutic — thick walls that breathe, cool in summer and warm in winter, built from the same ground they sit on. Guests often report sleeping better in one night here than they have in months. That is not by accident; it is the earth doing what it has always done.

Villager family home layout — The larger villager home is sized for a couple — room enough for a cradle or a small child's bed when the family grows. The smaller companion unit suits a single person or a couple travelling light. Both are intentionally modest — comfort without excess, designed to draw life outward into the community rather than inward behind a door.

Compact earthen studio — tiny home layout — Sixty compact earthen studios for residents rebuilding their lives — enough space to rest, but not so much that isolation becomes the default. The simplicity is deliberate: a small home nudges you outside, toward the fire pit, the gardens, the workshop, and the people around you. Community is the real shelter here.

Artisan workshops — carpentry, ironsmith, loom weaving, seamstress and hat shop — Carpenters, blacksmiths, weavers, and seamstresses are all villagers — earning real wages for skilled work. Every piece made here is sold within the community or to visiting tourists, keeping income circulating inside the village.

Village center — market, café, gardens and beehives tended by villager workers — The market, café, gardens, and beehives are the beating heart of the village. The beekeeper, gardeners, and café staff are all villagers earning a living wage — nurturing the land and feeding the community they helped build.

Maintenance workshop — solar panels, welding bay, ATVs and tools wall — Solar panels, welding bays, ATVs, and a full wall of tools — kept running by a maintenance crew of villagers. Keeping the infrastructure humming is skilled, essential work, and villagers are paid fairly for every hour they put in.

Village Doc — earthen clinic with doctor, nurse, waiting area and natural medicine — The doctor and nurse are the two outside professionals in the village — the only roles where expertise cannot be improvised. Together they run an earthen clinic offering natural medicine and primary care to every resident, regardless of income.

Frontier Theater — villager performances and community events — The theater runs on donations and tourist ticket sales. Villager actors, performers, and stagehands earn wages from every production — income they use toward rent, food, medical care, and personal savings.

Cottage industries — bakery, art gallery, herbal shop, honey and jams, printers — Villagers operate every shop — from the bakery and art gallery to the herbal apothecary, honey stall, and print studio. Tourists can browse, purchase locally made goods, and book hands-on lessons. Every sale supports the village economy.

Craft workshops — carpentry, ironsmith, loom weaving, seamstress and hat shop — Skilled trade workshops give residents meaningful work in carpentry, blacksmithing, loom weaving, and dressmaking. Visitors are welcome to commission bespoke pieces or take guided lessons — putting skilled wages directly into villagers' hands.

The Village Spa — operated by villagers, open to tourists — The spa is staffed entirely by villagers — trained therapists, attendants, and wellness practitioners earning a steady wage. Open to tourists, spa revenue flows directly back into the community, supporting residents' food, medical care, and savings.

As I rode my Harley around the USA, I saw so many people experiencing homelessness, as well in Oregon, that it broke my heart. With my digital background and my passion for fitness, I devised a plan to raise funds without begging. That is how KritFit came about — comprehensive, affordable, and built with good intentions. KritFit supports your fitness while your subscription will make it possible to help fund a future project to home the homeless in a unique village atmosphere.

🌿

Earth-First

Semi-subterranean earthen homes with living turf roofs. No exposed concrete. No industrial metal. Built in harmony with the forest.

🏘️

Self-Sustaining

Organic farms, zero-mile market, bakery, candle maker, butcher, coffee shop, wood-fired saunas. A complete, living economy.

🤝

Dignity by Design

Every capable resident holds an operational role. True healing requires both professional care and the psychological dignity of being needed.

HOW LONG WILL IT TAKE TO FUND?

Based on KritFit app growth scenarios · 60% of net profit allocated to the Huldufólk fund · includes Nutritionist + Store revenue

App Scenario	Subscribers	Annual → Fund	🌿 With Volunteers, Donations & Free Land	Without
Moderately Successful	50,000	~$1.4M / yr	4 years	11 years
Successful	75,000	~$2.0M / yr	3 years	8 years
Very Successful	100,000	~$2.8M / yr	2 years	6 years
Virally Successful	500,000	~$13M / yr	5 months	15 months

🌿 With Community Support

Target: $4M–$8M cash · Volunteer labour, donated materials & free/discounted land reduce the cash requirement by ~60–70% from full market value. Best-case: funded in under a year at viral scale.

Full Market Rate

Target: $13M–$24M cash · No grants, no donated labour, commercial land rates. Still achievable — just slower. A successful app funds it within a generation.

ARPU ~$4.25/mo blended (User $2.34 · Trainer/Nutritionist $5.67 · Gym $89 flat + store commissions) · 60% net profit directed to the Huldufólk fund

Net Operating Profit

~$3.3M

per year · village only · at 85% tourist occupancy

♻️ Self-Funding Growth

Profits are reinvested into two things: more resident homes to house more people, and expanded tourist facilities to generate more revenue — each feeds the other.

📐 The Virtuous Cycle

More tourist facilities → more revenue → more homes built → more villagers working → more goods and classes → more tourist draw. The village compounds itself.

💼 Hermit Salaries

Tiny studio residents earn real wages in the café, bakery, forge, carpentry shop, weaving studio, seamstress, honey stall, and spa — rent-free living plus income to save.

60 villagers earn avg. $875/mo (Level 1–10: $250–$1,500) · 30 keepers earn $2,500/mo · Bus runs city trips + tourist pickups · Box truck handles supplier runs · Solar + rainwater = near-zero utility costs

Village Roles & Progression

You Arrive With Nothing. You Leave With Everything.

Every new arrival earns enough to pay a small rent ($200), utilities ($20), and food ($40). Everyone begins at the same level — Nykomling — and works their way up through demonstrated contribution. Wages rise with skill and responsibility. There is no ceiling except your own ambition. Every role listed below is a real paid position, not a volunteer slot or a favour. This is a functioning economy with Norse structure and modern dignity.

Lvl	Norse Title	English	Monthly Wage	Primary Responsibilities
1	Nykomling	Newcomer	$250	Grounds maintenance, dish-washing, compost turning, general cleaning
2	Lærling	Apprentice	$400	Assisted roles in bakery, café, forge, weaving — learning one craft under a senior
3	Handverkar	Craftsperson	$550	Independent craft production — baking, sewing, woodwork, honey, candles, soap
4	Køpar	Trader	$700	Market stall operation, tourist sales, supply runs, inventory tracking
5	Husmann	Householder	$850	Responsible for one accommodation unit — guest check-in, cleanliness, minor repairs
6	Meister	Master Craftsperson	$1,000	Leads a workshop, trains Level 1–3 arrivals, sets quality standards for output
7	Styrmann	Pilot / Guide	$1,100	Village tours, bus/truck driving, external supplier liaison, event coordination
8	Rådgjevar	Advisor	$1,200	Mentors new arrivals, conflict resolution, programme planning, community wellbeing
9	Høvding	Chieftain	$1,350	Department head — oversees a full operational area (hospitality, production, land, health)
10	Forvalter	Steward	$1,500	Village co-steward — strategic decisions, new node scouting, external partnerships

🏡 Affordable Living

Every resident pays a small contribution — $200 rent, $20 utilities, $40 food — totalling $260/mo. Even at Level 1 wages of $250, the shortfall is minimal and covered within weeks of earning a first rise.

📈 Earn Your Level

Advancement is based on demonstrated skill and contribution — not seniority or politics. A determined Nykomling can reach Meister within a year.

🌿 Community Code

Respect the land. Respect each other. Contribute honestly. No hierarchy of worth — only hierarchy of role. Everyone eats together. Everyone matters.

🚀 Exit on Your Terms

This is not a commune — it is a launchpad. When you are ready to leave with savings, skills, and confidence, the village celebrates you. The door is always open to return.

All wages are pre-tax · Accommodation, meals from communal kitchen, and utilities are provided at no cost · Level advancement reviewed quarterly by the village council
