@InvictusDude Cool! I know at one point FitBit had a vibration alarm... and I remember some kind of wearable that tracked sleep phases and would wake you when you're at your lightest sleep near the desired wake time.
@InvictusDude Oh, also, idk if makes a diff for morning sensitivity to light, but I have my bathroom light set up to only come on very minimally dim if my bed lights are off and it's after bedtime, but then max brightness in the am if cloudy (or off if getting sufficient lumens from window)
