• iPhoneアプリ情報&サポート

An app that supports your personal practice.

What you can do with this app

  • It is a application that counts the number of times the sound generated during excercise.
  • It is possible to count the excercise sound louder than the surrounding sounds.
  • Examples:
    Tennis serve practice
    Volley practice
    Baseball tee batting
    Golf putting practice
    Basketball shoot practice, etc.

Target volume

  • Set the volume to be counted.
  • If the setting value is too low, surrounding sounds will be counted.
  • Adjust so that it does not react to the surrounding sounds, but only to the target motion.
If the setting value is too low…
  • For example, even the sound of a routine before service of tennis might be counted.


  • Set the counting interval.
  • Even if multiple sounds are generated by one action, it is a setting to count them as once.
  • Set the number of seconds for the next action in good rhythm after an action is completed.

  • The screen turns red during the interval.
If the interval is too short…

  • For example, when you hit a serve against a wall, the app might count all the sounds not only the sound you hit a ball.
