Gyroscope Test
Rotate your device to test the gyroscope sensor. The cube follows your movements.
About Gyroscope Sensors
A gyroscope measures the rate of rotation around three axes. Combined with an accelerometer, it enables precise motion tracking for gaming, VR, and image stabilization.
Understanding the Values
- Alpha (α): Rotation around the Z-axis (compass heading, 0°–360°)
- Beta (β): Rotation around the X-axis (tilting forward/backward, -180° to 180°)
- Gamma (γ): Rotation around the Y-axis (tilting left/right, -90° to 90°)
How to Read a Gyroscope Test Result
A healthy gyroscope should respond smoothly with very little delay when you rotate the device. Sudden jumps, drifting angles, or values that snap back can point to calibration problems, blocked permissions, or a phone that lacks a dedicated gyro sensor.
If screen rotation works in system apps but not here, allow motion access in the browser and compare results with the Accelerometer Test. Devices that rely mostly on accelerometer data can still rotate the display, but 3D motion tracking usually feels much less precise.
Why Gyroscopes Matter in Real Apps
Gyroscopes are especially important for AR filters, racing games, VR viewers, panoramic photography, and motion-controlled aiming. They provide rotational precision that an accelerometer alone cannot match during fast movement.
Frequently Asked Questions
Why do I need to grant permission?
iOS 13+ requires explicit user permission to access motion sensors for privacy. This prevents websites from fingerprinting your device movements without consent.
The values aren't changing?
Ensure you're on a mobile device with a gyroscope. Desktop computers typically don't have this sensor. Also check that motion permissions are allowed in your browser settings.
