Yoga Free for iPad: Asanas and Exercises
"Yoga Free for iPad is a decent poses, with step by step directions and customized Programs you can build from beginner to guru level. Nice music, thorough instructions, and the ability to add the program with in app purchasing.
The only limitation I have found to yoga of exercise Programs for iPad is the small screen, and trying to keep up with the details if not verbally queued. These Programs may do better on the Mac app store, if they take advantage of iMac display sizes."
