We have seen some of the applications of smart translator of our time, but lately Google translator and crush all. And now offers translation into more than 70 languages??, with entry via text, and handwritten words or symbols, spoken words or even text recognition via the camera (awkward in some cases, word for word). Then you can give the translation in text or spoken to you. Basic application that can do all this with a data connection and language packs that you can download for free so you can use it abroad without Wi-Fi or fear of roaming data.
