Summary

**React Native Developer Needed — Fitness Tracking App (Expo + Supabase + Stripe)** I'm an online fitness coach with an established audience and I've already built a fully designed, fully functional workout tracking app in React (web). I need a developer to convert it to React Native (Expo), wire up the backend, and submit it to the App Store. **The app is already built. This is NOT a design job.** The UI, user flow, features, and logic are all done. You're converting and shipping. --- **What the app does:** - Users set up their training program once (days + exercises) - Each session they pick a day, log weights and reps per set - Previous session numbers shown automatically so they know what to beat - Progress charts per exercise - Session notes - Full history log - Dark / light mode --- **What I need you to do:** 1. Convert the existing React code to React Native using Expo 2. Set up Supabase for user authentication and data storage (per-user data, not local storage) 3. Integrate Stripe for $9.99/month subscription with a paywall on app open 4. Submit the finished app to the Apple App Store 5. (Bonus) Google Play Store submission --- **Requirements:** - Strong React Native + Expo experience - Experience with Supabase (auth + database) - Experience with Stripe subscriptions on mobile (RevenueCat is fine) - Has shipped at least one app to the App Store — please share examples - Clean communication, can hit a timeline --- **Budget:** $500–$1,500 fixed price (open to discussion based on your experience) **Timeline:** Looking to be live on the App Store within 4–6 weeks Please start your proposal with the last app you shipped to the App Store so I know you've read this. Generic proposals will be ignored. Let's build something great.
