Helpful but buggy
I like this app. You can mix vocal tracks to a choice of music tracks, and you can control the volume of both. But lately it will stop playing the track in the middle. The timer does not show you how long a track is , so youre not sure if youve started a 5 minute meditation or a 15 minute one. The timer also jumps ahead two , three seconds or even longer at a time. When the iPad rotates, the volume alters. There are a lot of free tracks, but a lot of them are lame. I still use it, mainly for some of the background tracks. They need to update and revamp this app and it will be even rather awesome.
