What is Step Counter?
A session-based pedometer that reads your phone's accelerometer through the DeviceMotion API and counts steps with on-device peak detection. Start a session and walk with the screen on — it tracks steps, distance, pace, and a daily goal ring. All processing stays in the browser: no account, no upload, no background tracking. Desktops and devices without a motion sensor show a disabled state.

Motion access needed
This counter reads your phone's motion sensor. Grant access to begin.
Motion access denied
Re-enable motion access in your browser settings, then reload the page.
No motion sensor
Step counting needs a phone or tablet with an accelerometer. This device doesn't expose one.
Secure connection needed
Motion sensors only work over HTTPS. Open this tool on the live site (https://mentria.ai). A local dev server reached by LAN IP over plain HTTP cannot expose the sensor.
