Size AI requires a device with a working LiDAR sensor.If you see the “Compatible Device” screen, it usually means:- Your device does not support LiDAR, or- The LiDAR sensor is not being detected properlyThis is not a bug in most cases. The app blocks access to ensure accurate measurements.Supported devices include:iPhone Models:• iPhone 12 Pro / Pro Max• iPhone 13 Pro / Pro Max• iPhone 14 Pro / Pro Max• iPhone 15 Pro / Pro Max• iPhone 16 Pro / Pro Max• iPhone 17 Pro / Pro MaxiPad Models:• iPad Pro 11" (2020 and later)• iPad Pro 12.9" (2020 and later)All models include the LiDAR sensor required for professional accuracy.
You can test this using Apple’s pre-installed Measure app:1. Open the Measure app2. Point your camera at an object3. Try measuring distanceIf this works smoothly, your LiDAR sensor is functioning correctly.
Try the following:1. Test your LiDAR sensorUse the Measure app (see above)2. Reinstall the app1. Delete Size AI completely2. Update to the latest iOS version3. Restart your device4. Reinstall the appIf the issue persists, contact support and we’ll help debug it.
For best results:- Lay the garment flat on a surface- Make sure sleeves are fully visible (especially for pit-to-pit)- Avoid folds or overlapping fabric- Use good lighting- Capture the entire garment in frameSmall variations can occur depending on setup. For more information on best practices, please view our Guides.
If your device does not have LiDAR support, Size AI will not function as intended.In some cases, users may assume the app is broken, but the limitation is due to hardware compatibility, not the app itself.If you’re unsure, check:- Your device model- LiDAR functionality using the Measure app
