I have a Lumia 950 (AT&t). I does without the band, but I don't check the stats since I'm always wearing my band. My Lumia 640 that I use for advance testing does track motion confirmed.
20 tiles are nice but there are no new categories. How about some new categories???
Also, I wish MS included "When in Use" option (in addition to Never and Always) for location services for iOS. Frankly, I don't like MS Health app draining my phone battery and tracking where I am all the time.
