Hey HN,

I've just released an update to my iPhone/Apple Watch app Daylight Goals which includes a new feature - your Daylight Recap for 2025.

If you've been wearing an Apple Watch for the past year it has been recording your time spent outdoors (So long as the screen is mostly uncovered.) My app charts and graphs it, along with giving you daily goal updates to make sure you get your 20 mintues of sunlight per day.

The recap feature is free, you just need to close out the paywall during onboarding.

This is cool! It'd be interesting to correlate this with Vitamin D too.

Thanks! I'm looking into Vitamin D estimation for a future version, the main issue is there are a ton of factors that need to be considered, the main one is simply how much skin you have exposed when you are outdoors. A simple question but it requires a dedicated user to update the app with their wardrobe every day.

Tangential to the post’s content (and the app is cool, by the way), but is anybody ever bothered by app/website landing pages that look like they’re AI-generated? I’m not even sure most of them are, but current AI models are so effective at creating those icon + feature grids that now every time I see one, my eyebrow raises so high it hits the ceiling.
