Track your real-time Acceleration in m/s².
An online accelerometer is a browser-based tool that uses your phone's motion sensors to measure real-time acceleration in m/s². With this phone accelerometer test, you can instantly check how quickly your device speeds up, slows down, or changes direction without installing any app.
Acceleration is the rate of change of speed over time. For example, when a car goes from 0 to 20 km/h, your phone detects that increase in velocity and calculates the acceleration in meters per second squared. This acceleration test (m/s²) helps you analyze vehicle pickup, braking force, running motion, or sudden stops.
You can measure acceleration online by simply tapping the Start button and allowing motion access. The tool works in real time and shows positive acceleration when you speed up and negative values when you brake or slow down.
Measure real-time acceleration using your smartphone sensors and GPS by following these steps:
