The rating is important.

Instead of just saying "you did 500 push-ups this month", users have a competitive identity.

  1. Start workout

Tap START.

The app asks:

┌──────────────────────────────┐
│ PUSH-UPS │
│ │
│ Choose your challenge │
│ │
│ ┌────────────────────────┐ │
│ │ ⚡ 60 SECOND │ │
│ │ Maximum verified reps │ │

│ │ Compete for rating │ │

└──────────────────────────────┘
3. Camera positioning

This is one of the most important screens.

┌──────────────────────────────┐
│ │
│ CAMERA PREVIEW │
│ │
│ 👤 │
│ /│\ │
│ / \ │
│ │
│ ✓ Full body visible │
│ ✓ Good camera angle │
│ ✓ Good lighting │
│ │
│ Place phone 2–3m away │
│ │
│ [ READY ] │
└──────────────────────────────┘

The app shouldn't let someone start until the camera position is good enough.

  1. The actual workout

This should be extremely simple.

You don't want someone looking at a complicated UI while doing push-ups.

┌──────────────────────────────┐
│ PUSH-UPS │

└──────────────────────────────┘

The pose skeleton could optionally be overlaid on the user.

The 47 should only increment when the AI decides that a rep is valid.

  1. Invalid rep

This is where your product can become really compelling.

Suppose I do a half-rep.

Instead of counting it:

47

the app might show:

❌ REP REJECTED

Insufficient depth

Go slightly lower.

Then I continue.

This gives immediate feedback.

  1. Workout finished

This could be one of the most satisfying screens.

┌──────────────────────────────┐

└──────────────────────────────┘
7. Leaderboard

This should be one of the main parts of the app.

┌──────────────────────────────┐
│ LEADERBOARD │
│ │
│ 🌎 Global 🇮🇳 India 👥 Friends │
│ │
│ 1 Alex 2187 │
│ 2 Marcus 2114 │
│ 3 Arjun 2048 │
│ 4 Daniel 1987 │
│ 5 You 1778 │
│ │
│ ────────────────────────── │
│ │
│ YOUR RANK │
│ #427 │
│ │
│ 1,823 users below you │
│ │
└──────────────────────────────┘

You could have separate rankings for every exercise.

  1. Head-to-head battles

This is where I'd differentiate the product.

Someone challenges you:

Arjun challenged you

60-second push-up battle
┌──────────────────────────────┐
│ ⚔️ HEAD TO HEAD │
│ │
│ YOU ARJUN │
│ 62 58 │
│ │
│ 🟢 WINNER │
│ │
│ +32 Rating │
│ │
│ [ CHALLENGE AGAIN ] │
└──────────────────────────────┘

Now fitness becomes competitive.

  1. Your profile

I'd make profiles feel like competitive player profiles, not traditional fitness profiles.

10. The really interesting part: tournaments

Eventually:

IIT Madras vs IIT Delhi
🏆 UNIVERSITY FITNESS CUP

IIT MADRAS IIT DELHI

Pull-ups
████████████████ ███████████
3,921 3,104

text
    CURRENT SCORE

   IIT MADRAS
      2 - 1

Now you've moved from:

"fitness tracking app"

to

"competitive fitness platform."

That's where I think the concept has significantly more potential.

The overall app structure

I'd keep the bottom navigation to 5 things:

🏠 Home
⚔️ Compete
➕ Record
🏆 Leaderboard
👤 Profile

And the core loop becomes:

Record → AI verifies → Score → Rank → Challenge someone → Compete → Improve → Repeat

That's a much stronger product loop than simply:

Record → see calories burned → close app.

Pensiero

Validated and packaged Expo camera app with TypeScript fixes

Worked for 6m 50s

Risposta

Built the VERIFIT mobile app source as a React Native + Expo project. It targets Expo SDK 57 / React Native 0.86, consistent with the current Expo compatibility table, and uses Expo’s CameraView API for the camera workflow. (Expo Documentation)

Download the complete VERIFIT source code (.zip)

Included in the project:

  • Full 5-tab app: Home, Compete, Record, Leaderboard, Profile
  • Rating-first competitive identity, with rating and global rank changing after workouts
  • Daily challenge and challenge-mode selector
  • Real camera permission + camera preview
  • Camera positioning/readiness gate before starting
  • Minimal live workout experience with verified-rep counter
  • Instant REP REJECTED feedback with reasons such as insufficient depth or incomplete lockout
  • Form, ROM, consistency, rejected-rep and timer tracking
  • Workout-complete screen with PBs and rating changes
  • Native result sharing
  • Global / India / Friends leaderboards
  • Head-to-head battles
  • Player profile, records, achievements, win rate, rating progression
  • IIT Madras vs IIT Delhi tournament experience
  • Shared app state so results affect rating/rank/profile throughout the app
  • Replaceable PoseVerifier architecture for connecting a real pose model later

The important distinction is that I did not pretend the production AI exists. The camera is real, while src/services/verifier.ts currently contains a DemoPoseVerifier that simulates AI rep acceptance/rejection so the entire product flow is usable. Replace that implementation with MediaPipe, MoveNet, or your own on-device pose model and the UI/state architecture can remain unchanged.

To run it:

bash
cd verifit-app
npm install
npx expo install --fix
npm run start

Expo currently documents CameraView and useCameraPermissions as the supported camera APIs used by this implementation. (Expo Documentation)

I also checked all 19 TypeScript source files, and all relative imports resolve correctly. A full dependency/device build couldn't be completed inside this environment because npm package installation timed out, so the final native build should still be run locally after npm install.

The included README.md also documents exactly where to plug in production pose detection, joint-angle state machines, ROM thresholds, temporal smoothing, anti-cheat/liveness checks, and a server-authoritative Elo/Glicko-style rating backend.
