We're big fans of
Football English Soccerball, but even we aren't hardcore enough to be able to discuss the technicalities of the game in Portuguese. Thankfully, and just in time for the World Cup, Rosetta Stone (amongst others) is unveiling a Futebol Edition of its travel app, helping you to say escanteio (corner kick), un meio-campista (midfielder) and por favor, queremos saber onde fica o estádio (excuse me, we're looking for the stadium). The app, which is available for free on iOS and Android will give you tips on navigating public transport, but since all of the data is offline, it won't rinse your data connection as it does so. We've tried the app and it's missing a few practical phrases (o árbitro é um bastardo) but otherwise it's golden.
