Very happy to have this on IPhone
I am impressed by how many tutorials are available and the quality. Would like something better about advancing and going back on the moves - maybe just a button for forward and another for going back. The tutorials are from $.99 and up - most at $.99. So far I have purchased 2 at $.99 and they are very good - much depth and variation moves. It is worth a try - to see if you like it.
