Excellent app!
I use Tempo just about every time I practice. The interface is very simple and intuitive. Perhaps the best feature is the ability to tap a list of tempos to select one--largo or moderato or allegretto, say--rather than having to cycle laboriously up or down through various bpm settings. An excellent choice if you need a metronome app!
