Is there a proper introduction to this "new design"? I got the prompt today and am saying no for several reasons:
1) There is no going back. So I have to blindly opt in and then if I don't like it I can't go back? Hard pass.
2) Fitbit's own page on the subject is mostly text telling me how to do things but doesn't show me enough screenshots to know what to really expect: https://help.fitbit.com/articles/en_US/Help_article/2435
3) In the years I've been using the Fitbit app there have been no real usability improvements. And while I've gotten used to it in the current state of the app, a complete overhaul promises to bring about new "weirdness" I will be forced to adapt to. Take time zone management, where you have to scroll through a list ordered by region & city until you find the location you want. There is no search and so switching between various time zones often requires tons of scrolling instead of being able to type a few letters and have it filter down the list automatically like in the core iOS settings.
Sorry for the rant on #3, but I think their choice here speaks volumes on what to expect by a complete app overhaul. But really, #1 is the main one. If you want folks to opt-in to something and give feedback ... you have to provide them a way to opt-back out in case they don't like it.
@RobynHinds, @Giedre: If you or anyone else in this thread could provide more screenshots so others might know what they'd be getting into that would be helpful.
