CalzAI reads calories and macros from a single photo — entirely on your iPhone. No servers, no sign-up, no data leaving your pocket.
Your photos never leave your device.
Everything you need to understand a meal — and nothing you don't. Fast, private, and refreshingly simple.
Point your camera at a plate and CalzAI identifies the food in seconds. No searching, no barcodes, no typing.
Recognition runs with Core ML and Vision right on your iPhone. No cloud round-trip, so it's fast even in airplane mode.
Protein, carbs, and fat come from a bundled nutrition database — always shown as clear, honest estimates.
Half a plate or seconds? Drag the serving and every number updates instantly to match what you actually ate.
A calorie ring, day totals, and streaks keep you on track. Set targets that fit your body and your goals.
Send your logged energy to Apple Health if you want to — entirely optional and off until you turn it on.
No onboarding maze. Open the app, snap, and you're done.
Snap your meal or pick one from your library. The image stays on your phone — only a small thumbnail is ever saved.
CalzAI recognizes the food on-device and pulls calories and macros from its built-in nutrition database.
Fine-tune the portion, then add it to your diary. Watch your calorie ring and macro goals update in real time.
CalzAI was built offline-first. There's no backend to leak, because there's no backend at all.
No. Recognition happens entirely on your iPhone using Core ML and Vision. Your photos never leave the device, and only a small thumbnail is stored locally alongside each meal so you can recognize it in your diary.
The photo identifies the food; calories and macros then come from a bundled nutrition database scaled by the serving you choose. Values are honest estimates — always shown with a "~" — and are meant for awareness, not medical precision.
Never. CalzAI works the moment you open it. There's no sign-up, no email, and no password to remember.
Yes. Because everything runs on-device, CalzAI works fully offline — on a flight, on the trail, or anywhere with no signal.
CalzAI is free to start with a set number of scans. An optional subscription unlocks unlimited scanning and premium features. You can use the core experience without ever paying.
If you'd like to. Health sync is completely optional and off by default; CalzAI only requests HealthKit access at the moment you choose to enable it.
Free to download. Private by default. No account, no clutter — just a photo and an answer.
