This is a speed gun app designed for those who want to measure the speed of a ball. The app uses the distance and time it takes for the ball to travel from start to stop in order to calculate its speed. There are two ways to stop the measurement: either by tapping the button to start and stop, or by starting when the button is tapped and stopping when it is released. Users can choose the method that is most convenient for them.

The app also allows users to adjust the distance setting. By tapping the distance, users can change it to their desired value. The default setting is 18.44 meters. Additionally, users can select the unit of distance from either meters or feet on the setting screen.

In terms of speed units, the app offers the option to choose between kilometers per hour (KPH) and miles per hour (MPH). Users can change the speed unit on the setting screen according to their preference.
