A minimal desktop nutrition tracker. Built for people who know their macros.
Free · Open source · macOS · Windows · Linux
A native desktop window. No tabs to find, no app to install on your phone, no account to forget.
No onboarding quizzes. No goal-setting wizards. No motivational pop-ups. Just the few things you actually want a tracker to do.
One view per day. Swipe through your week like a slideshow of meals.
Register a food once with its macros. Log it forever with one click.
Rings, charts, streaks. Your week, at a glance — without spreadsheets.
Cmd+K opens the universe. Add anything in under a second.
All data stays local. No cloud, no account, no telemetry. Just SQLite.
PDF for your dietitian. CSV for your spreadsheet. Markdown for your notes.
Press ⌘K from anywhere. Start typing — Prowtein matches against your library and your most-eaten foods first. Hit return. Logged.
Add a food once — name, macros, default serving. From then on, it's two keystrokes to log. Your most-used foods float to the top automatically.
Seven days, seven bars, one streak. No badges, no confetti — just a quiet record of what you've been doing.
One binary per OS. No installer wizards, no electron-bloat — under 15 MB and ready in seconds.

Yes. Free, no trial, no premium tier. The source is on GitHub under MIT — clone it, audit it, fork it.
Locally, in a single SQLite file in your OS's app-data directory. You can copy it anywhere, back it up to your own cloud, or move it between machines manually.
Not yet, and probably not ever as a hosted service. Point Prowtein's data file at iCloud Drive / Dropbox / Syncthing and you get sync for free — without us holding your food log.
Always. Prowtein doesn't need an internet connection. There's no 'log in' screen because there's no account.
MIT-licensed. Contributions welcome — see CONTRIBUTING.md in the repo.
