Show HN: I built a daily sunlight tracker

>how most people aren’t getting enough

What are you basing this on? What counts as 'enough'? And how are you tracking light exposure?

Nice! An Android version would also be appreciated :)

Looks cool!

A couple questions:

(1) Are you supposed to join the waitlist to use this ("Get Early Access"), or can you just start using via TestFlight ("Download Today")? I see two different links on this page.

(2) How does this app measure the amount of light received by the Apple Watch? Does the Watch have such sensors and expose such APIs?

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!

Pretty cool! I’m working in this space right now with architects and building owners. The science has advanced unto a certain knowing of melatonin secretion getting in the way of mental alertness under poor artificial illumination.

Hit me up if you’re interested in learning more or how I can move your office space towards a renovation on the build owners dime: joseph@ledcompliant.con

Hormone optimization is just the newest way of calling someone the f slur since it’s not cool anymore.. f slur, soy, cuck, incel, now I also have to worry about how much sun I get if I want to avoid bullying. Give me a break

ummmmmm, if you dont have some kind of tan lines, you are not getting enough sunlight the app is pre loaded at birth .......though,I get it, as there is a significant demographic who will only trust there (beloved) device, and will benifit from the prompt, perhaps, perhaps not, as there is no possible way to break out all of the inumerable ways that human phisiology has adapted to ambient conditions on our planet, into seperate apps, so.....
