Mumet

Mumet is a metronome that lets you create a list of songs with different tempos. This way you can easily change from one tempo to another, or rather, from one song to another. Mumet also lets you set the time signature per song from 1/4 to 8/4. There is also a global "auto stop" function that will stop the beats after a certain number of bars. Best of luck with you practice!
