The Microsoft Band has a lot of potential and you can see that from the apps that third-party developers have come up with. Band Translate is a great example. It lets you ask for translations directly from the Microsoft Band. After installing the app, you can press and hold the action button on the Band and then say, „Translate [What you want to translate] to [In what language you want to be translated].“ The translation then shows up on your Microsoft Band.
