Hello, I am currently hoping to use Accelerometer and Gyroscope in the healthcare application.

I have confirmed that safari, web browser, and web app need to request permission to access the sensors mentioned above, especially from iOS 13. However, I have not found any information about whether the permission is required when accessing through the iOS application.

Also, when I tried to use any application (using mentioned two sensors) in the App Store, I couldn't check the procedure for requesting permission.

I would like to clarify this. If anyone knows whether the iOS application have to ask the permission to access Accelerometer and Gyroscope, please reply. (or, if anyone gives me the URLs, I'd like to check and learn about it.)

Thank you for reading.

Requirement is described in CoreMotion documentation:

Important

An iOS app linked on or after iOS 10.0 must include usage description keys in its Info.plist file for the types of data it needs. Failure to include these keys cause the app to crash. To access motion and fitness data specifically, it must include NSMotionUsageDescription.
