As I recall, it handles all of your personal and enterprise email, calendar events, etc. It was supposedly going to be similar to the Hub on BlackBerry except it apparently doesn't include voice calls and messages, SMS or any kind of social messaging like the Hub. I think it was going to be introduced on the Note 7 and then possibly released to other Samsung devices. It's apparently available now in the Play store but I don't know of anyone using it. If you want an integrated solution, try BlackBerry Hub+.
