Google Translate for Android will now offer downloadable offline language packs. So now when you're staring at a weird sign in a country where you don't speak the language, your phone will actually be able to help you.
This solves one of the hugely obvious problems with the translation app. Until now, if you weren't connected to the Internet the app was useless. When you're travelling abroad, you usually don't have access to the Internet. That also happens to be when translations are most useful. [Google Play and Google]
