App Idea - Interval Coach

How many people listen to music while riding the bike trainer inside? I also know that there's a large population of cyclists who listen while riding outside, which I don't recommend, but I know you're out there. How about an app that downloads an interval workout that your coach or yourself sets up online, and provides audio/visual/haptic cues for when to start or stop each interval?

The user would be able to select a set of intervals on the application on their phone (ex: 20min @ 100% LT, 10 min rest, etc), and then click the "start" button. They could have music playing in the background for entertainment. Whenever an interval starts or stops, an audio cue would play, the phone would vibrate, and maybe display a description in large text of what the next command is. An example would be audio plays "Upcoming Interval...20 seconds at max effort...(waits a few seconds)...*beep*beep*beeeeeeeep" and you start the interval. The phone vibrates during the beeps to give some haptic feedback, and if the proximity sensor isn't covered, it displays a description of the interval along with a countdown and some encouraging phrases.

Another feature would allow a coach to set up the athlete's intervals online, and when the athlete was ready to start, the app would download the set of intervals to the phone and start them. Apparently this is a similar feature to what Training Peaks software is already offering, but I think this takes it to a different level by actually participating in the intervals.
