No. Once a course is purchased, it is assigned to the user App Store account. To download it again, go to the Course catalogue, find the course you are interested in and click “Buy”. A window will pop up saying that the course has already been purchased and can be re-downloaded for free (the same as it is with other applications bought at the App Store).

Version 1.1 includes a button ‘Already bought’. When you click on it, the application will check which courses have already been bought by the user but have not been downloaded yet and activates the ‘Download course’ button for them. This option is useful in case there are problems with downloading a course that has already been paid for.
