NeoME — Mobile Health & Wellness App (React Native + Firebase) · Matt Alexius

NeoME is a gamified mobile wellness app built with React Native Expo, TypeScript, and Firebase — tracking fitness, nutrition, and personal goals.

NeoME is a mobile-based health and wellness application developed using React Native Expo and TypeScript, with Firebase as the backend for authentication and real-time data storage. It promotes holistic well-being by helping users track fitness, nutrition, and personal goals through an engaging and interactive interface. The app also supports gamified features, encouraging users to maintain a balanced and healthy lifestyle.

The approach

Built mobile-first in React Native Expo so the same codebase ships to iOS and Android. Firebase handles auth, real-time data sync, and push notifications, so the app feels live without us managing servers. Gamification (streaks, badges, daily goals) is layered on top of the core tracking flow to keep users coming back.

What I learned

Cross-platform mobile is a lot of compromise. Animations that feel native on iOS feel sluggish on mid-range Android, and Firebase’s realtime listeners are powerful but easy to over-fetch. Spending half a day cleaning up listener cleanup logic saved hours of battery drain on real devices.
