The best Ive found.

I love this app. Ive tried a lot of meditation apps and havent liked most very well. This one just gets it right (for me anyway) in every regard that I can think of. It really makes the practice much more enjoyable and doable for me.

(The only thing I would add is the option to set a reminder to meditate, but there are other ways to accomplish that and I dont hold the lack of this option against the app or its creators.)
