Translation app

 Google translate. This is an app that translates words or sentences from one language to another. Very useful for people traveling to foreign countries. It works 2 ways: you can type or you can talk to it. It will show you the translation in the second language. For some languages (the more common ones) there is an option to talk the translation back to you. There are around 30 languages available right now with new ones to be added in the future.
