Atwater is your pocket health app. Snap a meal or scan a barcode, connect the band you already wear, and see Fuel, Burn and Recovery in one place.
Free to start. No account needed. One email on launch day, nothing else.
Try it. Tap a dish.
Most people quit food diaries within a week because typing every meal is boring. Atwater turns it into a two-second habit.
Point your camera at the plate. Atwater knows 2,000+ dishes, from ramen and tacos to poke bowls and pancakes.
Half a plate or seconds? Slide it. The numbers follow.
Packaged snack? Scan the code and the label's nutrition drops straight in.
Every meal lands in Fuel, against a daily target set from your goal.
Meet the original calorie counter.
Atwater's respiration calorimeter, USDA National Agricultural Library.In the 1890s, chemist Wilbur Atwater built a room-sized machine to measure what food is worth to the body. His shortcut is still on every nutrition label: 4, 4 and 9. Go on, build a plate.
No new gadget. With Pro, Atwater reads what your watch or band already saves to Apple Health or Health Connect, then puts food, movement and rest side by side.
Built to work on your phone, without an account. Here is the deal, in plain words.
Open the app and start. No sign-up, no password, no profile on our servers.
Dish recognition is built to run on your phone, so your meal photos are not uploaded.
Scan a packaged food and only its barcode number goes out, to look up the label. Nothing else.
3 scans a day, free for ever. Pro adds your band, Recovery and unlimited scans.

Very likely. Atwater recognises 2,000+ dishes from kitchens everywhere: sushi, tacos, ramen, shakshuka, pad thai, biryani, pierogi and plenty more. If it misses one, correct it once and it remembers.
No. Food logging and Fuel work on the phone alone. With Pro, a band adds Burn and Recovery through Apple Health or Health Connect.
They are estimates, like any food label or tracker. You can always fix the dish or the portion, and Atwater remembers the foods you pick.
No. Atwater helps you understand your habits. It does not diagnose or treat anything. Ask your doctor about medical questions.
Any time, in your App Store or Google Play subscription settings. Cancel at least 24 hours before renewal and you won't be charged again.
