About the Accelerometer Test
The Accelerometer Test shows live acceleration on all three axes, with and without gravity, plus the rotation rate reported by the device. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Checking the motion sensor after a drop.
- Confirming a fitness or step-counting app has working hardware underneath it.
Frequently asked questions
What should a phone lying flat read?
Roughly zero on the X and Y axes for acceleration with gravity, and about 9.8 m/s² on Z — that is gravity itself. Large non-zero readings on a still, flat phone suggest a miscalibrated or damaged sensor.
Why is acceleration without gravity always near zero?
Because it only shows movement you are causing. Shake the device and it will jump.
Does the Accelerometer Test cost anything?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Is the Accelerometer Test safe to use with private information?
No. The Accelerometer Test runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What problem does the Accelerometer Test solve?
In practice it gets used for three things: checking the motion sensor after a drop. Confirming a fitness or step-counting app has working hardware underneath it. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Why does the test start on its own?
No installation, no extension and no driver. The Accelerometer Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
