Ive used this metronome for over a year, and this app is the best. I bought the pro version which is about $3, but it is so worth it. The features of this metronome beats any mechanical metronome over $20. There are few things you cant do with this metronome.
It is loud, and with the pro version, you can get different sounds according to your taste, different rhythms, different beats, etc.
Dont use any other one. This is the best metronome app on the App Store.
