Description
About Gyroscope Test
Introduction
This page shows rotation rate when the browser provides motion sensors. Desktops usually cannot. iPhone may ask for permission. Expect a quick sensor sanity check, not flight-instrument precision.
What this tool does
It displays rotation-rate axes from device motion (or related APIs) when available.
When to use it
Use it on a phone to confirm rotation events after permission.
How it works
Supported: many mobile browsers with sensors. Unsupported: most desktops. Why: hardware and privacy gating. Permissions: motion on iOS when prompted. Hardware: phone/tablet with a gyroscope. Expected: values change as you rotate, or unsupported on desktop.
Step-by-step instructions
- Open the page on a phone.
- Allow motion access if asked.
- Rotate the device and watch the readouts.
Common problems
Desktop unsupported is normal. Flat-on-table may show near-zero rates until you turn the device.
Privacy explanation
Rotation samples stay local. Nothing is uploaded.
