The estimate was wrong
Usually it is the weight rather than the food. Open the meal and tap the food: type the grams it actually was, or change it to the right food — everything recalculates. For what a photo cannot show, like oil or a sauce, tap Fix something and say it in your own words. For anything packaged, the barcode is more reliable than a photograph will ever be.
Photographs that include the whole plate, taken from slightly above with a fork or your hand in frame, come out noticeably better than a close-up. There is nothing in the shot to judge size against otherwise, and the app will say so.
The barcode was not found
Product data comes from Open Food Facts, a free public database whose coverage is uneven by country and thinnest on supermarket own-brands. When a code is missing, the app opens the manual form with the barcode already filled in — the label in your hand is the fastest source. You can also add the product to Open Food Facts yourself, which helps the next person.
Subscriptions, cancelling and refunds
Subscriptions are handled entirely by Apple, so we cannot see, change, cancel or refund one.
- Cancel: Settings on your iPhone, tap your name, then Subscriptions.
- Refund: reportaproblem.apple.com.
- You paid but the app still asks: open You › Subscription and tap Restore purchases. If that does not do it, check the iPhone is signed in to the same Apple Account that made the purchase. No CheckCal account is needed for a subscription to work.
Apple Health shows nothing
Tap Steps on Today, or open You › Apple Health and tap Continue, then choose in Apple Health's sheet what CheckCal may read and write. If you turned something off there, iOS will not ask again: open the Health app, go to Sharing, then Apps, find CheckCal and turn it on. Apple Health deliberately does not tell an app what was refused, so the app cannot warn you about this itself.
A photo says “Photo reading is off”
Photos are read by an AI model from Google, and CheckCal asks before the first one is sent. If you said not now, or turned it off later, open You › Privacy and turn on Read photos with AI: photos that were waiting are read at once.
Something is wrong with my day's numbers
Meals are grouped by the time they were logged. If a late-night meal landed on the wrong day, delete it and add it again — and tell us, because that is a bug worth knowing about.
Signing in, and why it is optional
Everything in CheckCal works without an account, reading photographs included — the subscription is what pays for that. Signing in makes your diary follow you to a new phone. You can sign out under You; the diary stays on the phone.
Sign in with Apple, with Google, or with an email address and a password. A forgotten password is reset from the sign-in screen — tap “Forgot the password?” and a link arrives by email; we cannot see or reset it ourselves. If a sign-in does not complete, try it again before writing to us — and if it still does not, write to us, because a sign-in that fails twice is our problem rather than yours.
Deleting your data
Open You in the app and tap Delete account and data. To be sure it is you, you sign in once more; then your diary is removed from our database, Sign in with Apple's access is revoked, your identity is removed from our sign-in provider, and everything on the phone is erased. Photographs only ever lived on your phone. It happens when you tap it and it cannot be undone — there is no waiting period and nothing to email us about.
If you never signed in, You › Erase all data on this phone erases everything, and there is nothing of yours on our side beyond an anonymous count of photos read. See the privacy policy.
Reporting something serious
Security issues, or an estimate that could put somebody at risk, go to the same address with urgent in the subject line.
