How many times have you wanted to easily loop a section of a song, slow it down, or change the pitch? Capo makes this task easy. It is a really solid app on the Mac, and it should be a great hit on the iPhone. I highly recommend this app to help musicians with rehearsal and transcription.
Capo for iPhone
Capo for iPhone isn’t cheap. This is a premium application, and I’m not just talking about its $20 price tag. It’s easy to use, pleasing to look at, and as helpful as all get out. – MacWorld
