Headspace is a meditation app for iPhone and I believe Android as well. Headspace is a guided meditation app, and all you need to take is ten minutes. Headspace kind of turns meditation into a game as well, there are levels and you can compete / play against friends. There are animations and other cool graphics as well to keep you motivated.

This is the best meditation app I've seen so far, it's free for the first ten levels so you can try it out than after that you need a paid subscription. I've been using this to cope with all of the stress in my life lately. I'm not sure if I'll buy the subscription, but it's worth a try for the first ten levels!
