Early morning just means that you will have to spend longer. I watched a video on youtube where a doctor recommends this app to calculate how much vitamin D you will get from the sun at any time of the day, that takes into account, your latitude, age, skin color, etc. It doesn't seem to use any data from your phone or share any personal data, but it does have an ad at the bottom of the screen.
I agree Jackie! I've read that the best time is early morning until 11am before the burning hours
