Description

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

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.

Solo Forge is licensed under GPL-3.0.

What’s new (0.4.0)

Solo Forge can now sync with Health Connect, so weight and workouts recorded by other apps on your phone show up here without retyping them. Import and export are separate switches in Settings, both off by default, and each only asks for the permissions it needs. As always this stays on your device: Health Connect is Android's local health store, and nothing is sent anywhere.
