About this role
JavaScript, Mobile App Development, iPhone, Android, iOS Development, Flutter, Data Visualization · I need a clean, intuitive fitness app whose single, central purpose is progress tracking—no meal plans or workout libraries, just rock-solid data capture and easy-to-read insights. Users must be able to record their weight, log the performance of every workout, and store body-measurement snapshots, then view trends over time through charts and simple stats.
I’d like the same codebase (or tightly aligned builds) deployed to iOS, Android, and a responsive web dashboard so clients can update data from any device. Feel free to recommend React Native, Flutter, or another modern stack that will keep maintenance fast and cost-effective; what matters is a fluid UX, secure cloud sync, and the flexibility to add new metrics later.
Acceptance criteria • iOS, Android, and web versions released to TestFlight / internal Google Play track / staging URL • Weight, workout-performance, and body-measurement logging flows fully functional and syncing across devices • Visual progress reports (line and bar charts) rendering in under two seconds on average mobile hardware • Basic account system with email or social sign-in and GDPR-compliant data storage • Brief technical hand-off document and
