Mobile Accelerometer & Motion Vector Tester

Test linear acceleration and gravity vectors along the X, Y, and Z physical axes. Listens to DeviceMotionEvent accelerationIncludingGravity properties to render live acceleration meters and dynamic tilt indicators.

3-Axis Accelerometer & Bubble Level

X-Axis (Lateral):
0.00 m/s²
Y-Axis (Longitudinal):
0.00 m/s²
Z-Axis (Vertical):
9.81 m/s²

How to use this test

  1. Hold phone flat; observe Z-axis reading near 9.8 m/s2 (Earth gravity).
  2. Tilt phone left and right to observe X-axis shifts.
  3. Tilt phone forward and backward to observe Y-axis shifts.
  4. Gently shake device to view dynamic acceleration spikes.

How to understand your result

Looks good: Motion sensors reported continuous linear acceleration across all three axes.

Troubleshooting: what to try next

  • On iOS Safari, tap 'Request Sensor Permission' button to authorize motion access.
  • Desktop PCs without motion sensors will display an informative unsupported state.

What this test cannot tell you

Desktop computers without built-in accelerometers cannot generate motion events.
