NeoME is a mobile wellness app with game-style tracking for fitness, nutrition, and personal goals. Built with React Native Expo, TypeScript, and Firebase.

NeoME is a health and wellness app built with React Native Expo and TypeScript, with Firebase handling sign-in and real-time data. Users track their fitness, nutrition, and personal goals, and game features like streaks give them a reason to keep at it.

The approach

We built it in React Native Expo so one codebase runs on both iOS and Android. Firebase covers auth, real-time sync, and push notifications, which gave us live updates without running our own servers. Streaks, badges, and daily goals sit on top of the tracking flow to keep people coming back.

What I learned

Cross-platform mobile takes a lot of compromise. Animations that felt native on iOS were sluggish on mid-range Android phones. Firebase's realtime listeners are easy to use and just as easy to over-fetch with. I spent half a day fixing how we cleaned up listeners, and it saved hours of battery drain on real devices.
