PLEASE Read this carefully before using the app :

1st : when you install the app for the first time make sure that you're connected to the internet to synchronize with Courses Source (Keep connect to receive any new courses when they get realized)

2nd : if you want to download any course you should :
-- go to the bottom of the page (Under "DOWNLOAD TUTORIAL"image)
-- you'll found this: The Post {Name of Course} appeared first on {A Website URL}... > Click on "{Name of Course}" to go to the original page to download the course (I did this to save the rights of the source site)

** When you download a course, you download a TORRENT FILE that already loads the entire of course (So make sure you have Utorrent app in your phone)​
