Speedometer HD is a free car dashboard app for driving that will give you all the information you need to drive safely.

It displays the current speed in either miles per hour or kilometers per hour and the top speed achieved. It also shows the current gear in use. You can also set the top speed to be shown on the screen, and the app will also show the time remaining until the next signal is detected.

If you are using the app to detect the speed of your car, you can set the sensitivity to be higher or lower than the default value.

The app will give you all the necessary information you need to drive safely.
