Many bugs

The review of the first version was good therefore I bought this new version but it turned out that it has many bugs and unusable. First, after importing data and setup your course the whole data deleted after backing up to Dropbox. Second, the reports are wrong and not valid. I hope that the author will consider making extensive testing for all the functions to make it usable. The app will be great and sufficient.
