This means you can translate to and from any language in any app. It is a complete keyboard that has a single button added for translation. Works in Whatsapp, Skype, Facebook, Twitter, or any app that uses a keyboard.
The translate button has two flags on it, showing the current selected languages for translation. A single click on the button is all that is needed for a translation straight away. Change the language setting? Just do a long press, change the languages, and the button will show the new flags.
No more copying and pasting translations! Just a single click and you are done, in any app, for (almost) any language.
Since update 3.0 the keyboard also supports 'swype', the popular way of typing fast.
Note that Translator Keyboard needs an internet connection to work (this can be either wifi, 2g, 3g, or 4g).
After the success on Android, we have now also launched this app on iOS. Tell your 'other' friends that they can download it here: https://itunes.apple.com/en/app/translator-keyboard/id1061001839
Good luck translating, have fun!
