I wear both FitBit Charge HR as well as Apple Watch on both my wrists. Crazy about tracking? I was actually being asked several times, at work especially when meeting the clients. I shared with them that FitBit gives me the advantage of competing with my friends on the daily goals. Apple Watch, kind of hard not to have it now, since I could read the push notifications on my wrist.
Just got the notification to update the Apple Watch to watchOS 2. The catch, about 22 hours remaining for a 518MB file. Guess so many Apple Watch users are downloading at the same time.
