Gyroscope test
Tap Start, then tilt and rotate your phone. The marker and the numbers follow it if the gyroscope works.
Gyroscope test workspace
Privacy: Rotation and tilt values are shown on this page only. No motion data, sensor stream, or device identifier is sent anywhere.
How to use
4 short steps.
Tap Start gyroscope
On iPhone, Safari asks for Motion and Orientation access. Choose Allow.
Tilt the phone forward and sideways
The marker slides toward the low edge and the pitch and roll angles change.
Spin the phone flat
Yaw changes as you turn the phone on a table. Rotation speed shows how fast it is turning.
Stop or reset
Stop keeps the last values on screen. Reset clears them for another try.
What the result means
Match what you see to one of these.
If the marker follows the phone and rotation speed changes, your gyroscope works
Gyro aiming in games and VR head tracking both rely on this sensor. A phone that passes here has the hardware.
If pitch and roll change but rotation speed stays unavailable, the phone may have no gyroscope
Some budget phones estimate tilt from the accelerometer alone. Games that need a gyroscope will not offer gyro controls.
If nothing changes, the browser is not getting sensor data
Desktop browsers and some private modes have no motion sensors. Open the page on the phone and allow motion access.
Troubleshooting
If the test fails, try these in order.
Allow motion access again
On iPhone, reload the page and tap Start to get the prompt back. On Android, allow Motion sensors in the site settings, then retest.
Use the phone, not a computer
Laptops and desktops rarely have a gyroscope. Open this page in Chrome or Safari on the phone and tap Start.
Turn off rotation lock and restart
Some phones pause sensors while locked or in battery saver. Unlock rotation, restart, and try again.
Calibrate in the phone's own tool
Samsung's *#0*# menu and many Android settings menus include a sensor screen. Calibrate there, then retest here.
What this test can't tell you
Where a browser check stops.
- The browser rounds, throttles, and sometimes fuses sensor values. This page shows response, not calibrated accuracy.
- Yaw comes from DeviceOrientationEvent and is not a reliable compass heading in every browser.
- Game input lag cannot be measured here. A working gyroscope on this page does not rule out lag inside a game.
FAQ
Common questions about this test.
Does my phone have a gyroscope?
If the marker follows the phone and the rotation speed numbers change when you turn it, yes. Nearly every phone made since 2015 has one, apart from some budget models.
What does a gyroscope detect?
It measures how fast the phone rotates around three axes, in degrees per second. Phones combine it with the accelerometer to work out tilt and direction.
What is the difference between a gyroscope and an accelerometer?
A gyroscope senses rotation speed. An accelerometer senses movement and gravity, which gives tilt. Try the accelerometer test to compare.
Why does gyro aiming feel delayed in games?
Delay comes from the game, the screen, and the phone's processing, not the sensor alone. A browser page cannot measure that latency.
