Content is excellent. Software is good but could be improved. Almost every time my iPad goes to sleep, I have to reenter my password when wake it up. It would be better to remain logged in longer, maybe one day, or indefinitely? Then I have to find the place I was, which takes some time. It would be better if the software remembered where I was when it last closed out so I could immediately go back to where I was working. Also, I have all access pass and navigation is somewhat confusing because of a lot of it seems to be about buying other courses which I don't need to do. Also should have a search function so if there is a specific song in one of the courses I could find it quickly by searching song name.
