Best of breed but a couple suggestions
This app is very easy to figure out, very easy to use, and very adaptable. The guided meditations are very useful too. I do have two suggestions regarding those: First, there should be a search function so you dont have to search potentially all 499 to find one on, lets say, Sleep; and second, the Back button should take you back to where you just came from rather than the top of the list ( you could always add a top button for that). A solid 3-1/2 stars but would easily be four with some nav/search tweaks.
