Sensor Viewer

Visualize gyroscope, accelerometer, and compass readings on supported mobile devices.

Click the button to start reading (iOS requires motion and orientation permission).

The phone model rotates with the device. The compass prefers iOS webkitCompassHeading and otherwise approximates 360 - alpha.

Total acceleration magnitude |a|--

The bars show acceleration including gravity, in a -20 to 20 m/s² range. A flat device is close to 9.8 m/s².

alpha / beta / gamma（°/s）-- / -- / --

Gyroscope angular velocity is shown in a -360 to 360 °/s range; rotate the phone to see the bars move.

Open on a supported phone, grant motion access when requested, and rotate the device to inspect readings.
