Many people fear not being unable to communicate with people from another country while traveling. Google Translate takes a bit of the edge off, quickly translating either written text or spoken words. I can even use the app to do the speaking for me, and input text through my camera or handwriting. The app can translate 103 languages with a data connection and 52 when I am offline. It can’t handle Tamarian, but it’s sure to be a handy tool here on Earth. Another option is Microsoft Translator, which offers 60 offline languages, travel phrasebooks, a real-time conversation mode, and actually translates Klingon.
