This is a great app!! It scans your playlist and adjusts the BPM of your songs (with no loss of pitch) and builds you a 15, 30, or 45 minute workout that includes intervals and progressive resistance. I get in a great workout....and the best part....a 45 minute hard elliptical workout is over in what seems like 10 minutes!! Buy it now!
