Refresh Rate Test
Estimate the refresh cadence your browser can observe. This check runs locally unless you choose the network speed test.

No camera, microphone or sensor data leaves your device.
-Measured with 90 browser animation frames
How it works
Start the test and follow the browser prompt where needed. DeviceKit never stores camera, microphone, precise location or test history. Results describe browser-observable behavior, not a professional hardware certification.
Questions
Is this test private?
Yes. Media and sensor checks run in your browser. Network speed requests are temporary and anonymous.
Why is this unavailable?
Some browser APIs need HTTPS, a compatible device or a permission granted after clicking Start test.
