Sensor tests
Check the sensors that make phones and tablets tick — multi-touch tracking, the vibration motor and motion sensors — right in your browser, with nothing sent to a server.
Multi-touch screen test See how many fingers your touchscreen can track at once. Each touch is drawn live with its own marker, and the test shows the current and maximum number of simultaneous touches — all in your browser, nothing uploaded. Gyroscope & Motion Sensor Test Test your phone or tablet's gyroscope and accelerometer right in the browser. See live orientation (alpha, beta, gamma), acceleration and a tilt visual that moves as you rotate your device. Everything runs locally, nothing is uploaded. Phone Vibration Motor Test Test your phone's vibration motor right in the browser. Trigger short, long, double and SOS haptic patterns to confirm the motor works. Everything runs locally on your device and nothing is uploaded.
