Helps the user to convert cholesterol into vitamin D


Using this application may reduce your risk of high cholesterol and the need to spend money on cholesterol lowering drugs.Your skin uses UVB rays from the sun to convert cholesterol to vitamin D. However, UVB rays only penetrate the earths atmosphere when the sun has an altitude angle that is greater than 50 degrees. This application uses longitude, latitude, time of day and day of the year to compute the altitude angle of the sun. This application also sends the user a notification when the altitude angle of the sun reaches 50 degrees and its maximum angle.During the winter months when the sun does not reach an altitude angle of 50 degrees, no notifications are sent.

Jednoduchá aplikácia, nepotrebuje registráciu. Upozorní, kedy do atmosféry preniká UVB, ktoré je potrebné na tvorbu vit D

Nice simple app without nagging, stupid ads etc. Seems to have a little trouble with daylight savings time though - switchover was last night and the time window for being outside moved two hours.

Simple and easy, no ads :)

It definitely needs to be redesigned its adequate but it's very clumsy not user-friendly. It could be easier to get a total count IU and be able to track supplement vitamins taken all this is just very unusual

Simple, weird picture choice.
