This app is called Ease into 5K (though originally it was called Couch to 5K [c25k]). I started this in 08/2011 and have been running a 5K (and a 7K!) every month since 09/2011. I'm currently wrapping up the Bridge to 10K app and will start Hal Hidgon's Half-marathon 2 program at the end of April. I highly recommend the apps!
