Mood▲97Hey 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.
