Solo Forge is a free and open source Android fitness app: an intermittent fasting timer, calorie and macro counter, weight tracker, and workout timer in one. No ads, no tracking, fully offline.It is built around local data ownership:
* No backend
* No accounts
* No analytics
* No crash reporting
* Android cloud backup disabled
* Full backup and restore to a single file, with optional auto-backup to a folder you choose
Features:
* Intermittent fasting timer with 16:8, 18:6, 20:4, and 36 hour modes
* State-driven fasting reminders instead of daily notification spam
* Food photo analysis using your own OpenRouter API key
* Manual meal entry and editable macro estimates
* Local calorie and macro goals
* Weight history with charting
* Simple, interval, and exercise/rest workout timers
* Dashboard for fasting, nutrition, weight, workout time, and streaks
* Daily journal notes on the progress calendar
* Optional Health Connect sync for weight and workouts, so entries recorded by a scale or tracker do not need retyping
Solo Forge sends a network request only when you start food photo analysis. That request goes to OpenRouter using the API key you provide. All saved meals, weight entries, workouts, fasting history, settings, and exports remain local to your device.
