Clean Architecture Flutter app using the Provider pattern for scalable state management. The exercise library (900+ entries with HD video) is bundled locally and synced with a remote CMS for updates. Workout sessions are managed as state machines - handling timers, exercise sequencing, and rest periods. Offline mode caches downloaded workouts and videos to local storage. In-app subscription handling manages free vs. premium access gates. A voice coach layer triggers text-to-speech cues tied to workout timer events.
