# Gyroscope and accelerometer

On-device gyroscopes and accelerometers can supply data about a device’s movement in the physical world.

You can use accelerometer and gyroscope data to provide experiences based on real-time, motion-based information in apps and games that run in iOS, iPadOS, and watchOS. tvOS apps can use gyroscope data from the Siri Remote. For developer guidance, see [Core Motion](https://developer.apple.com/documentation/CoreMotion).

## [Best practices](https://developer.apple.com/design/human-interface-guidelines/gyro-and-accelerometer#Best-practices)

**Use motion data only to offer a tangible benefit to people.** For example, a fitness app might use the data to provide feedback about people’s activity and general health, and a game might use the data to enhance gameplay. Avoid gathering data simply to have the data.

Important

If your experience needs to access motion data from a device, you must provide copy that explains why. The first time your app or game tries to access this type of data, the system includes your copy in a permission request, where people can grant or deny access.

**Outside of active gameplay, avoid using accelerometers or gyroscopes for the direct manipulation of your interface.** Some motion-based gestures may be difficult to replicate precisely, may be physically challenging for some people to perform, and may affect battery usage.

## [Platform considerations](https://developer.apple.com/design/human-interface-guidelines/gyro-and-accelerometer#Platform-considerations)

 _No additional considerations for iOS, iPadOS, macOS, tvOS, visionOS, or watchOS._
