Ive been using this app for a while now and on the whole I think this app is great. Like being able to create and save playlists. It would be great to transfer those playlists to iTunes though.
What I find frustrating is not being able to change all the bpms at once. Having to do each one individually is time consuming. Also, the bpm lock "slips" when you return to the app after leaving app for a while. For instance, I had to change 119 bpm to 90 bpm. I had to exit the app and when I came back to it the bpm went to 119, or higher. I had to go back in and change everything all again. It also seems that the Tempo cant find the bpm a lot of the time.
Sometimes its easier to go back to a good old cd and pitch control from the machine, but having access to Tempo Magic Pro has its merits as well.
