Gyroscope & Accelerometer Test Online
A free tool to test your phone's gyroscope, accelerometer, and motion sensors. Includes 3D cube visualization, spirit level, real-time graphs, accuracy scoring, and CSV data export — all in the browser, no installation required.
How to Use
Navigate to this page in a mobile browser on a device with a gyroscope (iPhone, Android phone or tablet).
Tap "Enable Sensors". On iOS, a system prompt will appear — tap "Allow". Permission is requested only once.
Switch between tabs: 3D cube (gyroscope), accelerometer, spirit level, graphs. Rotate and tilt your device — data updates instantly.
Place your device on a flat surface, open the "Accuracy" tab and tap "Start Test". The tool measures drift over 5 seconds and gives a stability score.
Tap "Export CSV" to save recorded sensor readings to a file. Data includes all gyroscope, accelerometer axes and rotation rate.

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.
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).
How do I calibrate the gyroscope?
Place your device on a flat surface for 10 seconds. If drift persists, restart your device. On iOS you can reset calibration via Settings > Privacy > Location Services > System Services > Compass Calibration.
