Cal 3D: AI Calorie Counter
Food Scanner & Macro Tracker
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Most accurate calorie counter.
Cal 3D uses 3D scanning, depth and volume, so your numbers are actually right.
HOW TO USE CAL 3D:
1) Answer a few questions. We set your daily goal.
2) Move your phone around your plate.*
3) See the grams and calories for each food.*
Other apps take one photo. A photo only sees the top. It cannot see the back, and it cannot see how tall the pile is. So they ask you to guess. One cup? A medium portion? You pick one and hope.
Cal 3D does not make you guess. Your phone sees the plate from every side. It works out how much space each food takes up, then turns that into grams. One number for every food. Not one guess for the whole plate.
You can fix anything. Change an amount. Fix a name. Delete what does not belong. Your changes stay.

NOTE: Cal 3D is not a medical device. It does not treat or cure anything. We measure how much space your food takes up. Grams and calories are worked out from that, so they are estimates. Talk to a doctor before you change the way you eat.
