I love this app, it functions great on most aspects and has really helped me with tricky poses. True sometimes you get clipping, but its an ipad app, not a desktop program. It works GREAT for the money!
My only major point of issue is the camera rotation. I can never seem to get the figure to turn left/right without them turning diagonally. If you and in an X, Y, and Z axis rotation tool (like for the limbs only it moves the camera) that would be awesome. You wouldnt have to remove the current rotation method, just adding a "fine control" rotation method.
