Nice idea but bad execution

The design of this app is pretty and at first the lessons are fun but then the problems start. I bought several courses and with the newest version of the app I cannot download them at once but in order to use the app without internet connection. That sucks I don’t have internet all the time!
You cannot save vocabulary to a list, only if you pay extra for a premium membership. I mean come on vocabulary is the basic and I already paid for the courses. And please stop annoying me with this membership all the time. It pops up, sends you mails and push notifications all the time. I can really not recommend the app as it is. Don´t like it and will delete it now.
