What did you eat today?

Peer-reviewed research on AI dietary assessment finds photo-based calorie estimates land within roughly 5 to 15% of the true value for common foods, on par with a registered dietitian judging the same photo. Mixed bowls and heavy sauces are harder, so every estimate shows its confidence and adjusts with one tap. Our benchmark target is within 8% of a dietitian, re-tested each release.

Database apps are only as accurate as what you log, and most people underestimate portions by 20 to 30%. Reading the photo itself closes much of that gap. The research is consistent: AI is strong at identifying common foods (around 85 to 95%), and portion size from a 2-D photo is the main source of error. That is exactly why we let you nudge any estimate.

Yes. Snap a photo or type a meal and get calories and macros back free, with no signup for your first 3 tries. Create a free account, still free, for 10 AI estimates a day on the web. If you want unlimited, Pro is an optional paid membership: on calorietrack.ai it starts with a 3-day free trial, then $29.99 every 3 months ($9.99/mo) plus tax, and you can cancel anytime. You can also upgrade inside the Onmode iOS app.

Yes. calorietrack.ai is one of the few AI calorie trackers fully usable in any browser: Mac, Windows, Chromebook, work laptop. No App Store required. It is the web view of Onmode, so the same account and the same meals sync both ways. On iPhone there's also the native Onmode app if you prefer.

No, that's the whole point. The AI estimates portion size from the photo, and you can fine-tune with "a little more" or "a little less" if it looks off. No food scale, no measuring cups.

Snap your order (Chipotle, Chick-fil-A, In-N-Out, Starbucks, Subway, McDonald's, Taco Bell) and the AI reads what's on the plate to estimate calories and macros. For chains that post nutrition, you can compare the estimate against the official numbers yourself.

Best is whichever one you'll actually open every day. calorietrack.ai is built for people who want photo-first logging and web access from any device, plus Oni, the AI coach in the Onmode iPhone app, on the same account. Not just an iOS app behind a paywall. Try the demo above and judge for yourself.

No. We do not sell or share your data. You can try the demo with no email at all, and delete your account and everything in it any time.

Yes. On iPhone, the Onmode app syncs your log privately through iCloud, so it stays in sync on every Apple device you sign into. The same account also shows your meals on calorietrack.ai, synced both ways.

No native Android app yet, but the AI calorie tracker works great on Android in the browser. Add it to your home screen and it behaves like a native app, with the same free account and the same history.
