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. When you're traveling abroad, you usually don't have access to the Internet. That also happens to be when translations are most useful.
The new language packs will be available in fifty (!) languages. They aren't as comprehensive as the real thing, but you don't need to translate fine literature. You just need to find the bathroom. [Google Play and Google]
