I found a GREAT interval timer app in the iTunes store for 99 cents!!! It's called Round Timer and it works like a dream!!! I actually like it better than my Gymboss. I love it because I can never hear my Gymboss over my music when I'm doing sprint intervals outside, and IMO the vibrator feature is worthless. If you want to use the round timer while listening to music, all you do is start your playlist first and then set the timer. It will sound the alarm over your music. It's SO COOL and very easy to use, and SO cheap!!
