Speedometer is a very accurate speed gauge for measuring the speed of anything moving, like cars, bicycles, motorcycles, boats, planes, and even your bike.

It is a very simple speedometer, with an arrow that is displayed on the screen. The arrow is used to measure the speed, and it is measured in miles per hour (mph), kilometers per hour (km/h), or nautical miles per hour (km/h).

The measurement is made using GPS.

In order to use the speedometer, you need an active GPS connection, so make sure that you have a good connection, and that your GPS is working properly.
