flexify

Flexify is a private, offline-first workout tracker designed for logging gym sessions and tracking strength and cardio progress over time. Users can build workout plans around their preferred exercises and schedules, log weights, reps, cardio, and rest periods during training, and review exercise history with progress graphs. The app includes configurable features, light and dark themes, and a rest timer. All data stays on the device, and the app works without an internet connection. Flexify is built with Flutter and is available on F-Droid, Google Play, and the Microsoft Store. The project is open source under the MIT License, with build instructions and contribution guidelines provided in the repository.
