توضیحات:

This app produces regular, metrical ticks (beats, clicks, beats per minute).
This app can be set to variable beats per minute (BPM, tempi).
This app is used by musicians or composers to help keep a steady tempo as they play, or to work on irregular timing and tempo.

It is easy to use!

Note.
I don't guarantee that this app will work out well more than 208 BPM.
Fine bpm from 40 to 208 BPM.
