The app is very straightforward. I completed the setup and my first test in under five minutes.
I tested all the lights in my home and was shocked at how much blue light we had. This gave me the info I needed to make safer lighting choices.
This helps me check classroom lights at my tutoring center. The blue light readouts are very helpful.
I used this for my work-from-home lighting. Made changes after seeing the blue light levels. Really improved my sleep.
