— local-first workout and nutrition tracker
A pocket-sized training log for Android. Workouts, calories and macros, bodyweight, long-term progression — offline, on-device, no account, no feed.
why i built this
I was frustrated with the current generation of fitness apps. Most gate basic functionality behind subscriptions, overload the experience with social features and “AI coaching,” or make it hard to access your own data. I wanted something simpler: a fast, local-first tool focused on training, nutrition, and long-term progression.
The goal was something closer to a disciplined notebook than an engagement-driven platform. Logging should be immediate. Tracking macros shouldn’t require ads, feeds, or upsells. Your data should belong to you, work offline, and stay accessible for analysis over time. Adherence matters more than novelty.
It also reflects a philosophy: software should stay understandable, portable, and durable. Foundry is deliberately local-first with minimal cloud dependencies and straightforward export — not trying to be a social network, just doing a few core tasks well.
Android-only. No Play Store — the APK ships from Codeberg releases. Obtainium is strongly preferred: it watches the releases page and auto-installs every new build. Direct APK works too, but you'll be on the hook for updates.
- Install Obtainium from F-Droid or GitHub.
- Scan the QR from another device, or tap the link below on the phone itself.
