Why don't I see any Vitamin D in the daily and weekly forecast pages?
The app displays the time when the angle of the sun to your location is 50 ° or higher. This is due to the fact that optimal UVB rays are present at this time.
Hitting "Get Current Location" multiple times automatically adds to favorites multiple times?
Yes, this can happen if the app detects a different longitude and latitue even for the same location.
Does this mean that Vitamin D (UVB) has an on/off switch?
No, Vitamin D (UVB) does not have on/off switch. The amount of UVB gradually increases or decreases as the sun is rising and setting. This app calculates optimal Vitamin D time to ensure that you are getting the optimal UVB rays.
