a vitamin D tracker?
I did not expect this link today :D
This is good. My apartment windows face a wall. I haven’t been getting enough d hopefully this helps
according to this, best time for vit D is 9.30am - 5.30am. I always thought it was only the morning sun <10am
Very good

Started using this app a couple of weeks ago and now it’s an easy habit 👍
