I can't comment on the app, but all EASA countries are supposed to take their exam questions from the same question bank.
There will of course be differences (language, map and way points used for nav etc) but the same content should be covered.
If you're talking about questions, I'd look at
AirQuiz - Online Practice Examinations for Pilots . Their bank of questions is much larger, and they don't pretend to provide copies of the actual questions, but equivalents.
Training wise, the content itself isn't supposed to have changed, so any set of text books should work, although I don't know anyone who has exclusively used those DVDs. As others have said - the information has been split across different exams, but the laws of physics and the aircraft themselves haven't changed!
Just remember - the aim should be to learn things - not just pass the exams.
