I Use one cheap buying on amazon is made by ftlab and called smart uv checker it is a sensor for every apple/android phone just put it in the 3.5 jack download the app and run it. It works very well and is much cheaper than the other that you can find online (zoomed ones for example.)
It's only 25$! And it works well.

I saw this one https://www.amazon.com/Stokes-Publi..._12?ie=UTF8&psc=1&refRID=MPAR4DWKW84JG5MN9D1F and was going to buy it.

But does it measure uvb rays?
