About the Project

A cross-platform mobile app for tracking the 75-day challenge — a fixed-duration program of daily habits like training, reading, and hydration. The app keeps the daily ritual simple: check off today, see your streak, and get a clear view of how far you've come. Highlights: • Built with React Native and Expo for a single codebase across iOS and Android • Local-first data so the app stays fast and works offline • Clean, calm UI designed to be opened quickly and closed quickly

Challenges & Solutions

The hardest part of a habit app isn't tracking — it's designing something people don't quietly stop opening on day 12. The work was in keeping the daily flow as short as possible, choosing what to celebrate and what to leave silent, and making "missing a day" feel like a reset rather than a failure.
