Looks beautiful! Here are some thoughts:

- Having a dark theme seems logical for an app focused circadian rhythms, would be nice to have a dark appearance

- Not being able to switch between days by swiping felt quite annoying: the Home page requires two taps to change to another day, and the Progress page needs one — but it could’ve been a swipe. And the calendar on the Day page can’t be swiped down, only closed by tapping on the (x).

I hadn’t even realized that Apple had rolled out Time in Daylight — Apple Health hasn’t promoted or highlighted it like it does for other new Categories, and even then, the visualization still feels lacking.

I have been trying to get more consistent morning natural light exposure lately, so this is perfect timing!
