This app has a lot of good points; its got more than enough poses and routines for somebody to spend a good deal of time learning yoga, and the pictures and explanations are generally quite clear. Be aware that as of this writing, the music cannot be shut off. If you dont like the music (and it will get tiring), you have to set the volume to zero, and then the audio queue to change poses is also inaudible. Additionally, if you want to use the timer, youre stuck with two minutes for each pose. No more, no less. Other than that, its quite well put together; the developers just need to add an options screen where some of these little quirks can be adjusted.
