It syncs and offers a few settings, but it isn’t pretty
It does sync w/ the band, tells you if the band needs an update (it just came out, so no, it doesn’t), and offers a few settings (fewer than the phone apps.) I suppose it does work.
But the login screen was confusing (I had to close it the first time, since it just came up blank.) And the spacing of the text within the app reduces my opinion of the Microsoft brand overall… it seems like a very bad version of the (relatively elegant) modern/Metro style used in Windows, hastily constructed to offer the very minimal surface area it does offer.
