Mobile Gyroscope & Angular Rotation Rate Tester

Test angular rotation rate (alpha, beta, gamma) and device tilt in degrees per second. Captures DeviceMotionEvent rotationRate values to measure how fast the device rotates around its pitch, roll, and yaw axes.

Gyroscope Angular Velocity Lab

GYRO
Alpha (Yaw / Z):
0 °/s
Beta (Pitch / X):
0 °/s
Gamma (Roll / Y):
0 °/s

How to use this test

  1. Hold phone in hand and rotate it like a steering wheel.
  2. Observe the Alpha rotation rate indicator.
  3. Tilt phone forward and back to observe Beta rotation rate.
  4. Roll phone side to side to observe Gamma rotation rate.
  5. Confirm rates return to ~0 deg/s when stationary.

How to understand your result

Looks good: Gyroscope registered angular velocity during rotation and settled at zero when still.

Troubleshooting: what to try next

  • Budget entry-level smartphones sometimes omit a hardware gyroscope chip, relying on accelerometer estimation.

What this test cannot tell you

Requires dedicated gyroscope MEMS hardware chip. Not present in standard desktop PCs.
