A scan

Every step on the phone.

One photo to a logged meal, and none of it leaves the device.

Your day

What you ate, what you burned, how you recovered.

The free plan covers meals and today's Fuel. Atwater Pro adds your band's data, Burn, Recovery and trends.

Snap a meal

Photograph the plate or pick a photo. Atwater names the dish and fills in calories and macros for a typical portion.

Fix it in one tap

Change the dish or the grams and every number follows. You know the portion better than a photo does.

Fuel

What you ate today against your target, with protein, carbs and fat beside it.

Burn

Energy out from steps, workouts and resting energy, read from your phone's health store.

Recovery

A 0-100 estimate from your sleep, resting heart rate and HRV, compared with your own 14-day baseline.

One line a day

A plain suggestion linking how you recovered to what you still need to eat.

  1. 01

    Start from your body

    Height, weight, age and sex give a resting estimate.

  2. 02

    Pick a goal

    Lose, maintain or build muscle, and how many days a week you train.

  3. 03

    Get a plan

    Daily calories and protein, carbs and fat worked out from those choices. Override any number.

  4. 04

    Stay on it

    Reminders you choose: meal times, an evening check-in and a Sunday look back.

FAQ

Questions about Atwater.

Short answers. The full list lives on the FAQ page.

Is Atwater only a calorie counter?

No. It logs meals from a photo, and with Atwater Pro it brings in data from the band or watch you already wear, so food, activity, sleep and recovery sit in one daily view.

Does it work with my band?

If your band or watch saves its data to Apple Health (iPhone) or Health Connect (Android), Atwater can read it with your permission. Most major bands do, for at least some data types. Atwater does not connect to band makers directly.

Does a photo or my health data ever leave my phone?

No. Recognition and every score are worked out on the phone. Nothing is uploaded, and health data is never used for ads.

Does it work offline?

Yes. The recognition model is built into the app, so scanning needs no connection.

What does it cost?

Free: 3 scans a day and today's dashboard. Atwater Pro: $4.99 a month, $29.99 a year with a 7-day free trial, or $59.99 once. Prices vary by country and show in the app before you pay.

Is this medical advice?

No. Every number is an estimate. Atwater does not diagnose or treat anything. Talk to a doctor or dietitian for medical decisions.

Which phones?

iPhone and Android (Android 8 and later), both launching in December 2026.

Why the name?

Wilbur Atwater was the chemist who worked out, in the 1890s, that protein and carbs give about 4 calories per gram and fat about 9. Food labels still use his numbers, and so do we.
