Its a powerful metronome app that is super easy to use and intuitive to figure out. When you want a basic click to keep time, it doesnt get in the way. But when you want more control, its ready for you! I used it to easily program complex tempo and meter changes for Bartok - something no physical metronome has ever been able to do, and a task which is cumbersome on other metronome apps. It seems like there might be a bug that makes editing click tracks very difficult after the initial creation. Overall, however, well worth the money!
...I just wish the accent didnt keep turning back on every time I make a change... But this is a small gripe!
