Understanding Gyroscope Axes
Alpha (Z-axis)
Rotation around the vertical axis. Like a compass bearing — 0° to 360° representing the device's heading.
Beta (X-axis)
Front-to-back tilt. Tilting the top of the device toward you is positive (+). Range: -180° to 180°.
Gamma (Y-axis)
Left-to-right tilt. Tilting the device to the right is positive (+). Range: -90° to 90°.
Use Cases
App Development
Verify gyroscope data before building motion-based apps, games, or AR experiences.
Device Testing
Confirm your phone or tablet's gyroscope sensor is functioning correctly after repairs or updates.
Gaming
Check gyroscope accuracy and range for tilt-controlled games and VR/AR applications.
Education
Learn how gyroscopes and inertial measurement units (IMU) work in real devices.
Navigation
Understand how gyroscope data is used in navigation apps, step counters, and orientation-aware software.
QA Testing
Validate sensor readings during quality assurance testing for hardware or software products.
Frequently Asked Questions
What is a gyroscope?
A gyroscope measures rotational orientation and angular velocity. In smartphones it's a MEMS sensor that detects how the device is tilted and rotated in 3D space.
Why don't I see any readings?
Desktop computers don't have gyroscopes. Open this page on a smartphone or tablet. On iOS 13+, you must tap the button to grant permission first.
Is any data sent to a server?
No. All sensor data is processed locally in your browser. Nothing is transmitted — your motion data stays completely private on your device.
Why does iOS require permission?
Since iOS 13, Apple requires explicit user permission for motion sensors to protect privacy. Android and desktop browsers grant access automatically.
What's the difference between gyroscope and accelerometer?
A gyroscope measures rotational angles and spin. An accelerometer measures linear forces including gravity. Most smartphones have both sensors.
Does this work on all browsers?
It works on Chrome, Firefox, and Safari on mobile. The DeviceOrientationEvent API is widely supported on modern smartphones and tablets.
