I bought it... It's basically the compulsory routine book (routine, pictures, deductions) and it has the videos included for each level. I like it better than the book as pages can't be torn, etc. and it is one purchase that will cover the 8 years...
I like the idea of having it on my ipad rather than having to break out the book all the time, but wanted to wait and see what other people thought first.
Someone should develop an app where you can "side by side" your gymnast's routine from coach's eye against the gymnasts on the USAG video.
Coach's eye has been a great tool for my visual learners, but I think they would "get it" even more if they could see, frame by frame, where their skills look different than someone performing them more technically correctly. Ya know?
