It is an application to support exercise such as "5 times in one set of 10 seconds" which is often written in books on diet and stretching.
You may not be able to check the clock while exercising, but using this app will tell you the timing by sound.
Just set the "number" or "time" you want to play the rhythm sound and press the start button, and the rhythm will continue at regular intervals.
("Count" and "Time" can be switched by menu)
By touching the number / time display part, you can switch between the display of completed and remaining.
Operating time (in time mode): When the rhythm is ticked up to the specified time, the instrument emits an end sound and stops.
Number of executions (in count mode): When the rhythm is ticked up to the specified number of cycles, an end sound is heard and the operation stops.
One cycle: The number of beats in one cycle. At the end of the cycle, the rhythm changes. (If it is 3, it will be like Kokkopi, Kokkopi ...)
Rhythm: The interval at which the rhythm is cut. (The default value is "Normal = 1 second interval")
Volume: Adjust with Android media volume.
