I've recently started Brazilian Jiu-Jitsu and thought I might learn some basic Brazilian as well, given the opportunity to practice with assorted Native speakers.
In getting a proper dictionary, should I definitely aim for a specific Brazilian one, or would most Portuguese dictionaries be just fine?
Also, would be great if anyone could recommend a proper English<->Brazilian (or German or Danish) dictionary iOS App (preferably offline - I find mostly 'translator'-apps, phrasebooks, courses, learning games etc)
