What is Motion & Orientation Sensor Tester?
The Motion & Orientation Sensor Tester reads the DeviceMotion and DeviceOrientation APIs on phones and tablets and shows the raw values live: acceleration and gravity on three axes, rotation rates, alpha/beta/gamma orientation angles and a compass heading where the browser reports one. iOS 13+ permission requests are handled with a tap, updates are throttled to animation frames, and nothing is recorded or transmitted.
Key Benefits
- Verify motion hardware works without installing a native app
- Real device values for debugging sensor-driven web features
- One-tap handling of the iOS 13+ motion permission dialog
- Smooth animation-frame updates instead of janky event spam
- Compass heading support where the browser provides it
Common Use Cases
- •Checking whether a second-hand phone’s gyroscope still responds
- •Debugging a web game or AR feature that reacts to device tilt
- •Comparing sensor output across Android and iOS devices
- •Recalibrating expectations for compass-based navigation features
- •Demonstrating device APIs in a mobile web development class
How to Test Phone Motion Sensors
- Open the page on your phone: This tester is designed for touch devices with motion hardware. Open it in the phone browser for the most accurate readings.
- Grant sensor access: Press Start sensors and allow the motion permission. On iOS 13 and later the browser asks explicitly, and the tool handles that request.
- Read the live values: Tilt and move the device to watch acceleration, gravity, rotation and orientation values change. Compass heading appears where the browser reports it.
Key Features
- Live acceleration and gravity vectors on X, Y and Z axes
- Rotation rates around alpha, beta and gamma axes
- Orientation angles plus compass heading where supported
- One-tap iOS 13+ motion permission request handling
- Animation-frame throttled updates that stay smooth on phones
