Microsoft just updated its Translator app for iOS, Android, and Amazon Fire devices to support new optimised language packs that are (allegedly) up to 23 per cent better at helping you figure out how to say "where is the bathroom" on your next vacation. They also eat up around half as much space on your phone when you download them -- a wise move, since you don't want to be stuck without the ability to ask for directions if you're lost on your travels.
