Great app! At first none of the forms seemed to match up as we went through white belt and I gave up on the app. Starting with yellow belt everything is exactly what we are taught and I have found the app features absolutely fantastic! Dont forget - turn your app sideways and you see expanded view of form positions. Now I dont have to worry if I forget a position when learning in class. It is all here; video, diagram, pictures, terminology.
