I was looking for an app that would let students keep track of their rehearsal time in a method that included more than just how many minutes a day. I wanted them to create a much more informative log. I think this is it and it also has an iphone app to boot and it is FREE. Students can record their rehearsal into the online program and teachers can track their students.
