You can correct any estimate on the spot, and your correction carries over to future estimates of the same dish. Shooting in good light with the whole dish in frame improves accuracy. For food where the contents are hard to see, such as a rice bowl or soup, typing the dish name often gets you closer than a photo.

The built-in database holds about 2,500 items from Japan's official food composition data. Anything missing, you can add yourself. Foods you add join the shared database and show up in other people's searches too.

Barcodes for packaged food are looked up in Open Food Facts. Products that haven't been added yet, or labels that are worn or smudged, won't scan. When that happens, enter the item by hand from the nutrition label on the package.

Open the goal screen and pick a different objective — lose, maintain, gain, or stay healthy. Your daily calorie target and macro split are recalculated when you do.

Sign in with the same account and your synced logs are restored on the new device. Logs made while signed out live only on that device, so sign in before you switch phones. Meal photos are stored on your device, so the photos themselves don't transfer — the calories, macros, and other logged values do.

Syncing needs you to be signed in and online. AI estimation, food search, and sync don't work offline. Reopen the app somewhere with a connection. If it still doesn't sync, email us at the address above.

Go to Settings > Account and tap "Delete account". Your account and all server-side logs are deleted permanently and cannot be recovered. Data on your device is removed when you delete the app. Product information you contributed to the shared database remains, dissociated from you.

The core logging features are free. Prices and contents of the paid plans are shown in the app. On the free plan, ads may appear in the app.

Cancel from your device settings, not from inside the app. iPhone: Settings > (your name) > Subscriptions Android: Google Play > Profile > Payments and subscriptions > Subscriptions Subscriptions renew automatically unless you cancel at least 24 hours before the period ends. Canceling does not delete your account or your logs.

Payment goes through the App Store or Google Play, so refunds are decided by the store. Request one from your purchase history there.

Check that notifications are allowed for CaRoot in your device settings. Reminders are skipped for meals you've already logged. If you logged breakfast today, the breakfast reminder won't fire.

The app follows your device language (Japanese / English). Weight can be shown in kg or lb.

The values shown are automated estimates and are not guaranteed to be accurate or complete. Use them to see your trends, not as exact figures. CaRoot is not a substitute for medical care, diagnosis, or dietary counseling. If you have a medical condition, are pregnant or nursing, or need a restricted diet, talk to a doctor or registered dietitian.
