簡単にボーダー計算(回転率計算)-BorderCalc APP
With this app, you can easily measure the border by simply entering the amount invested and the number of balls.
You can calculate the border per 1000 yen using any amount such as 500 yen, 1000 yen, 2000 yen, etc.
Of course, it is also possible to derive the border from the balls you have stored or the balls you have.
You can also use the "difference ball calculation mode" to calculate the number of remaining balls you have.
You can record borders for up to 50 cars.
If it's popular, we may create an iOS version as well.
