Horrible app!
I have been dancing for 12 years and have seen ballet companies perform from all over the world. I thought this would be nice to have so I could practice over break. However, its not worth the time or money. The exercises are beginner at best. The dancer doing the exercises is making a good effort, but has bad technique. It isnt a good idea for any dancer to watch and absorb bad habits, as it can lead to problems in more difficult steps as well as greater chances of injury.
