This application automatically measures the number of times the whistle is blown.

Have you ever forgotten your whistle on the day of a sporting event?

It is the worst when none of the participants have a whistle.
Also, there may be times when you really don't want to blow the whistle used by someone else, but you have to be the referee!

This whistle app will help you in such a case.
Your phone can be used as a whistle.

There are two types of whistles: one long whistle and two long whistles, which can be distinguished on a case-by-case basis.

Furthermore, a unique feature of this whistle app is that it automatically records the number of times you have sounded your whistle.

You no longer need to remember how many times you have blown your whistle.
There is no need for a record keeper to keep track.

You can concentrate on the game as the referee of the match in front of you.
This will surely improve the quality of your refereeing decisions.

We hope you will take advantage of this application.
