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 โ 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.
Keep the screen on and this tab open while you walk.
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.
