多機能シャトルラン -運動フィットネスアプリ-

Sound source generation app for shuttle run

Normally, the distance of 20m starts from 8km / h (the speed gradually increases), but with this app, you can increase or decrease the speed.
You can perform a shuttle run at a speed that suits your physical condition, so I hope you can use it to solve your lack of exercise.

In addition, it has a function that allows you to continue running at a constant speed instead of gradually increasing the speed.
