I built an iOS health application combining fasting, weight, sleep and workout tracking, with offline-first storage, HealthKit synchronization and subscriptions.
The system behind the interface.
Health tracking connects several kinds of data and daily routines. The application brings fasting, sleep, workouts and weight into a native interface while supporting offline use and integration with Apple Health.
Architecture choices that shaped the product.
Offline-first storage supports everyday tracking when connectivity is unavailable.
HealthKit synchronization connects app tracking with the health data available on the device.
What I developed.
- Fasting, weight, sleep quality and workout tracking
- Offline-first hybrid storage and bidirectional HealthKit sync
- StoreKit 2 subscriptions, WidgetKit extensions and multilingual interfaces
The resulting system.
A native iOS health application available on the App Store, with tracking, integrations, subscriptions and widget surfaces.
