App Description
Ball speed measurement app
This is a speed gun app for those who want to know the ball speed.
The distance and time (from start to stop) are used to measure the speed of the ball.
● Measurement way
Start measurement when the ball is thrown, and stop measurement when the ball is caught. The time from the start to the stop is used to calculate the ball speed.
There are two ways to stop the measurement.
One is to tap the button to start and tap it again to stop. The other is to start when the button is tapped and stop when the button is released. Choose the one that is easier to use.
● Distance setting and units
Tap the distance to change it. The default setting is 18.44 meters. The unit of distance can be selected from "meters" and "feet" on the setting screen.
● Speed Unit
The unit of speed can be selected from “KPH” and “MPH". If you want to change it, do so on the setting screen.
