A gyroscope test, or gyroscope tester, checks whether a device's gyroscope sensor correctly reports rotation around its three axes, commonly called pitch, roll, and yaw, as you physically turn the device.

Open this page on a phone or tablet, grant motion sensor permission if asked, then rotate the device around each axis. The 3D model on screen should rotate to match your physical movement, and the pitch, roll, and yaw numbers should update live.

Pitch is tilting the top of the device forward or backward. Roll is tilting the device left or right around its front to back axis. Yaw is rotating the device flat, like spinning it on a table while it stays level. Together the three describe any possible rotation of the device.

Most laptops and desktop computers do not contain a physical gyroscope sensor, so there is nothing for the browser to read. This test is built for phones and tablets, which almost universally include one for auto rotation and motion based apps.

iOS requires an explicit user permission prompt before a website can access motion and orientation sensors, a privacy protection Apple added in iOS 13. Android generally grants this access without a separate prompt, though that can vary by browser and version.

A gyroscope senses rotation, how a device is turning around its own center. An accelerometer senses linear motion and orientation relative to gravity, such as whether the device is being shaken or which way is down. Many apps use both sensors together for a complete picture of movement.

No. Controllers such as the PS5 DualSense and Nintendo Joy Con do include a gyroscope for motion aiming, but the standard browser Gamepad API does not expose that sensor data, only phone and tablet motion sensors are readable through a web page.

Some devices report roll less smoothly than pitch and yaw due to how the underlying orientation math handles that particular axis near certain angles. Watching the numeric roll value directly, rather than only the visual model, gives the more reliable picture in those cases.

It can reveal obvious problems, such as an axis that never updates or values that jump erratically with no physical movement, but confirming a genuine hardware fault usually also involves comparing behavior against a known working device of the same model.

No. The gyroscope only reports rotation, not location. Tracking position or movement through space is handled by a combination of the accelerometer and, outdoors, GPS.

Yes, motion sensor access through the browser is a standard, permission gated web feature. This tool only reads sensor values to display them, it does not record or transmit anything.

No. This tool runs entirely in your mobile browser. There is nothing to download and no account to create.

Confirm you granted motion sensor permission if your browser prompted for it, and try reloading the page. Some browsers also require the page to be served over a secure connection for motion sensor access, which this site already provides.

No. Every reading happens locally in your browser and is not sent to a server unless you choose to export a report yourself.

Rotation rate is how fast the device is currently rotating around each axis, measured in degrees per second, as opposed to pitch, roll, and yaw, which describe the device's current absolute orientation. Showing both gives a fuller picture of the sensor's behavior.
