The classes are really good and for basically all levels. Even if you only speak English, theres more than enough to keep you busy.
The webcam feature is quite interesting. Its probably not as good as actual yoga lessons in a studio, but for those who cant afford the real thing, this is a really great alternative. Ive been doing it for three weeks on my PC and since Im travelling this weekend I tried to app, and Im sold.
