Hit your macros without logging every bite.
Macro is an AI-powered nutrition tracker for athletes and anyone serious about calories, protein, carbs and fat. Take a photo of your meal — get an instant estimate. No barcodes, no databases, no monthly fee.
No account required. Your data stays on your device.
Nutrition tracking that gets out of your way.
Built for lifters, runners, cyclists, climbers — anyone who cares about what they eat but hates the busywork.
Snap. Done.
Take a photo of your meal and the AI identifies ingredients, estimates portion sizes and computes macros in seconds.
Real macros, tracked
Calories, protein, net carbs and fat — with a running dashboard for the day. Edit or delete anything in one tap.
Your goals, your rules
Set custom kcal and macro targets that match your training block. Cut, maintain, bulk — nothing is locked behind a paywall.
Private by default
No account needed. Your food log lives in your browser, not a marketing database.
Built for athletes. Useful for everyone.
Traditional trackers make you scan barcodes and search databases. Macro flips it: point your camera, confirm the estimate, move on with your day. Whether you're prepping for a meet, chasing a PR, or just trying to eat with more intention — you get honest numbers without the friction.
- Photo-first logging — no typing meals out
- Athlete-tuned goal presets for cut / maintain / bulk
- Confidence indicators so you know when to double-check
- Works great on mobile as an add-to-home-screen app
Support the project
Macro will always be free. If you find it useful, you can support the project through Venmo. Donations help cover AI inference, hosting, and time spent shipping improvements. Even a few dollars makes a real difference for an independent project like this — no pressure, and no features are locked away for people who don't.
