I built a daily sunlight tracker▲46
I kept trying to explain how important outdoor light is and how most people aren’t getting enough. Eventually I figured that showing is more effective than telling. So we built a free app that uses your Apple Watch or iPhone to automatically track your light exposure throughout the day. It tells you if you’re getting enough, shows you how consistent you are, and rewards habits that support hormone balance. It's in beta on TestFlight, let me know what you think!

Mood▲97
Hey HN, I've had this idea stuck in my head ever since I published Year in Pixels [1]. I've been adding a little thing here and there to this app, and now it feels nice enough to share. It's very interesting what daily tracking does to one's mind. While I already have apps to track everything else like sleep, heart rate, etc., I was still missing something to track my mood. The simple act of thinking about how you feel a couple of times a day already changes things. A moment of reflection. I opted to add Astrology, Checks (habits), and other goodies. Hope you like it as much as I do. Best,…
