You will not find a better metronome for this price. The metronome function can be subdivided, As is common practice, there is a pitch generator, but not only that, a tuner too. I have used the tuner with sight singing. There are plenty of apps available for phones, and I have a few, but I really prefer to have this purpose specific device. The battery will last long, and I will have my phone available for other things when I need it.
