I found another interesting app for the Microsoft Band, one that using Cortana will translate speech to another language. From the Band you hold down the action button for 2 seconds to bring up Cortana and say something like “Translate Hospital to German” and then it uses Cortana to do the translation and send it back to the Band (Krankenhause for the non-German speaker).
Translate using your Microsoft Band! First install the Tile on your Microsoft Band from this app. Then hold down the action button on your Microsoft Band for 2 seconds. When Cortana begins listening say Translate [What you want to translate] to [In what language you want to be translated]. The Cortana app will open on your phone, and then open this app. Then this app will do the translations and send them to your Band.
