Natural Metronome

Does pretty much exactly what you'd expect! The only slight disappointment is that having paid for the additional metronome soundss, only two of the four actuallybproduce sound. OK, the money involved was not much, but it would be nice if they all worked :( ...But aside from that, it's fine!

This is the most useful metronome I've found, elegant, effective, and it has no ads. Excellent visual indication of the beat. The only drawback (developer - please take note!) is that at least one of the sounds needs to be louder and more penetrating. I paid for the additional sounds in the hope that one would be audible above my own voice (I'm a classical singer), but they're quieter than the free woodblock sound.

having a sound and synced lights is great. I prefer glancing to see if I am in time with the beat. Being able to hear the steady rhythm is essential.
