Pretty good app but the interval jumps are too high.

I like the idea of the app in that it coaches you in your headphones when to run or walk, so you dont have to constantly look at your watch for your intervals. Make sure your ringer is on or it wont prompt you when the screen is blank. My main complaint is that there is a huge jump in run intervals between weeks 2 and 3. Running is not my strong suit and going from a 1.5 minute run interval to three full minutes is too much of a jump. There needs to be a 2/2 interval in there first. Also, the app gets a little glitchy sometimes and can mess up where you are in your workout. I still hate running so if I miss a walk prompt or if the app glitches to the wrong set, its quite annoying.
