What helps us help faster

• Which iPhone and which iOS version?
• What did you do, what happened, what did you expect?
• A screenshot — it usually saves two emails.

Please do not send us health records or photos of people. We do not need them to troubleshoot.

“Estimated” instead of “Measured” — why?

Cal 3D labels every entry according to whether the volume was actually measured. If it says estimated, the measurement did not take. The three reasons, in this order:

1. The device has no LiDAR sensor. It is fitted to the Pro and Pro Max models from the iPhone 12 Pro onwards — so not to older Pro models such as the iPhone 11 Pro. On every other iPhone the app works fully, but by estimating. No update can change that.
2. The sweep was too short or too fast. Move the phone calmly in a half-circle around the plate for about three seconds, roughly 30 cm away.
3. The scene yields no depth. Very dark surroundings, highly reflective plates or glassware return too little usable depth data. The app then deliberately falls back to estimating instead of presenting an invented number as a measurement.

Why we would rather write “estimated” than quietly guess is explained on the method page.

The scan fails or aborts

• No connection: recognising the dish needs the internet. Without a network you can still log the meal manually.
• Daily limit reached: there is a per-day cap as an abuse guard. It sits far above normal use — if you hit it, write to us.
• Camera access denied: Settings → Cal 3D → enable Camera.

Subscription, cancellation and refunds

Subscriptions run through the App Store. We can neither see, end nor refund them — only the store can:

• Manage Apple subscriptions
• Request a refund from Apple

Deleting the app does not end a subscription. Who your contract is with, and what your rights are in detail, is on the cancellation and refunds page.

Restoring purchases

New iPhone, or reinstalled the app, and the paid features are locked? The subscription is tied to your Apple Account, not to an account with us. In the app, open Profile and tap Restore purchases — make sure you are signed in with the same Apple Account you bought with. Your diary data does not come back; it lived on the old device alone.

Deleting your data

Cal 3D has no user account; your data lives on your device. The instructions are on delete your data.

Something is not accessible

If a page does not work with your keyboard, screen reader or at high magnification, tell us — it is the fastest way to get it fixed. What we measured, and where this site still falls short, is written down in the accessibility statement.
