Microsoft released a cool app for the iPhone and Apple Watch on Thursday that automatically translates between 50 languages. What makes Microsoft Translator so cool is that you talk to it, and it converts what you say into whatever language you need. In essence, it's like your own personal Babel Fish or Star Trek universal translator. You can speak into your Apple Watch to convert what you say into different languages, and it it's too loud to play back the translation you can show the written version that appears on your iPhone or Apple Watch screen. Even better, it's free. You can pick up Microsoft Translator at Apple's iTunes-based App Store.
