Doesn't work at all...

I used it listening to external songs. Tried on 20 different songs from different genres. Not accurate on 1. I get a bpm from release, mixmeister, then Virtual Dj, so we have an accurate start point. It was not only way off but would give me different reads on the same song if I ran it 3 times. Horrible accuracy, how did they test this?

Worked for Me

I don't know why there are so many reviews saying that this doesn't work. I tested it by running a sequencer through various synths and a drum machine. I tried a number of combinations and it was always accurate to within 0.1 BPM. I'd give the 6 stars if I could just to offset some of the 1 star reviews.

Guitarist Getting Ready To Record Demos

This is amazing! I'm terrible at finding how many bpm my songs are and this gets it right on every time so far. Just play my jumbled weird Travis/Carter picking style and it figures it out. Solid app! It works!
