What it does
On iPhones with a LiDAR sensor, Calorix can estimate the physical volume of your food to improve portion accuracy. Portion size is the biggest source of error in calorie estimates, so measuring volume directly — rather than guessing from a flat photo — produces a more reliable calorie and macro estimate.
How to use it
- 1Open the camera capture on a LiDAR-equipped iPhone.
- 2Use the LiDAR scanning mode and move your phone around the plate as prompted.
- 3Calorix combines the depth data with AI food recognition to estimate volume and portions.
- 4Review the estimate and save.
Why it matters for calorie tracking
Two plates of the same food can differ a lot in calories purely by portion size. By sensing depth and volume, LiDAR scanning tightens the part of the estimate that's hardest to eyeball, giving you numbers you can trust more.
Devices & requirements
LiDAR scanning requires an iPhone (or iPad) model that includes a LiDAR sensor — typically the Pro models. On devices without LiDAR, Calorix falls back to standard AI photo analysis, which still works well.
FAQ
Which iPhones support LiDAR scanning?
iPhone and iPad Pro models that include a LiDAR sensor. On non-LiDAR devices, Calorix uses standard AI photo analysis instead.
Does LiDAR make calorie estimates more accurate?
It improves portion accuracy by measuring food volume directly, which is the biggest variable in a calorie estimate.
Do I have to use LiDAR?
No — it's an optional capture mode. Regular photo and voice logging remain available on every device.
