FAQ
Why do I need to grant permission?
iOS 13+ requires explicit permission for motion sensor access. This is a privacy feature by Apple. The permission dialog only appears once.
Does this work on desktop?
No. Gyroscope and accelerometer sensors are only available on mobile devices (phones and tablets). Desktop computers don't have these sensors.
What does the accuracy test measure?
It measures gyroscope drift — how much the readings change when the device is stationary. Lower drift means a more accurate and stable gyroscope.
Is my data sent anywhere?
No. All sensor data is processed locally in your browser. Nothing is uploaded to any server. The CSV export saves to your device.
What are Alpha, Beta, and Gamma?
Alpha is rotation around the Z-axis (yaw/compass), Beta is rotation around the X-axis (pitch/tilt forward-back), Gamma is rotation around the Y-axis (roll/tilt left-right).
