My wife started on the C25K about a month ago and really loved the program. So much she talked me into doing it (err... Just Swim... and Run?). For her it was a pain keeping track what time interval she was on, etc., until she found a few Podcasts that covered beeped. I was not a fan of the offerings, so I went looking for an app and came across this one. I only have completed the second workout of the first week, but I am very happy.
I play my playlist on the iPod, then kick off this app. I get audio cues, which are clearly heard over my music, and have no problems when the iPhone display locks (granted I can't glance at my time left until the next interval, but since I can hear the cue, there is little need). Once complete, the day is noted for future reference.
This is not to say there isn't room for improvement. For example, a list of pre-run stretches can be brought up. I would love to see a configurable time for each strech where the current strech is displayed, with audio cue when it is time to change(so once I memorize them I don't need to look). This, however, doesn't interfere with the core purpose of the app.
I am very happy with my purchase.
