It allows you to tap in your tempo (in case you have learned the song by feel and don’t know the actual tempo marking). You can also change the time signature and choose which beat you want accented (in case there’s a tricky section where you need to sing or play on the off beats). Perhaps most importantly, you can make a playlist of songs so that if you’re rehearsing a set list you can go straight into the next song without needing to change your settings. Absolutely a must have for any serious musician…and at $2.99 it’s a no-brainer!
