JaBIT is a powerful app for interval training, yet it is very easy to use. Although aimed at cyclists (it contains some features most suited for exercise bikes and trainers), it can successfully be used for any countdown timer and interval timer use - like running, weight lifting, circuit training and more.
It comes with a few built in example workouts, but the powerful workout editor makes creating new ones a breeze (make sure to check out the video), complete with nested sets and synchronized YouTube videos.
