About
A fully offline calisthenics fitness app built with React Native + Expo (managed workflow). Its standout feature is an interactive Skill Tree / Roadmap that visualizes calisthenics skills as connected nodes, progressing from beginner to expert. Skills unlock sequentially, a skill becomes available only after its prerequisites are completed. No backend, no internet connection, no external auth provider, every feature works offline. All data lives locally on the device (SQLite + AsyncStorage).
