Do not buy this!
At first this app was really cool because it allows you to listen to music while running. But about ten runs in it started to act up. The app out of nowhere will stop tracking your run, it has done this to me three times. I had no data for a very important run due to this. It used to play audio every five minutes to tell you your stats, then on one run it did not do so until 17 minutes in and then never did it again. The app also does have very difficult buttons to press that will not work inside your arm band at all. The other thing that is troublesome is that it is meant for endurance running and only has a microscopic counter for miles that is impossible to see in sunlight given that white numbering on the charcoal background.
