SpeedoMeter Lite is an app for measuring the average speed over a given distance. This can be used to measure the speed of a car, bike, or any other vehicle that is moving.

How to use SpeedoMeter Lite:

To use this app, you need to enter a known distance and start the measurement. The average speed is updated live during the measurement. When you reach the end point, you can stop the measurement and the results are added to the history.

To adjust the distance, you can use the “Distance” field and enter the new value.

You can press “Start” when you are at the start point.

To view the history of the measurements, you can press “Stop” and “Restart” or “Resume“.
