An offline-first training and nutrition tracker for Android. Plan routines, log workouts with built-in rest timers and a visual exercise library, track meals and macros, and review progress — all your data stays on your device in your own storage folder.
- Training — scheduled routines, a guided active-workout screen with rest timers, set/rep/weight logging, supersets and secondary exercises
- Exercise library — 1,324 exercises with animated demos, categories, and custom exercise support
- Nutrition — meal logging with a food database, macro/calorie tracking, water intake
- Progress — training history, charts, and body-metrics tracking
- AI (bring your own key) — weekly/daily training reviews, meal macro estimates from a description, and an AI routine builder. Works with OpenRouter, OpenAI, Gemini, or a custom endpoint; your key stays on your device and requests go straight to your provider
- Own your data — everything lives in a plain-text vault (.md) in a folder you pick on your device; view and edit it in Obsidian or any editor, export/import anytime. No servers, no accounts, no tracking.
Grab the latest signed APK from Releases — every push to main rebuilds it automatically. Requires Android 10+.
