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
Why free?

Serious nutrition tools shouldn't cost $80 a year.

Macro is a small, independent project. It's free because paywalling calorie tracking felt wrong. If it helps you and you'd like to chip in for AI and hosting costs, there's a donate button below — completely optional.
