Probably the best app of its kind. I needed it to check plant stands and there’s even a simplified indicator with a hint for which plants this amount of light is appropriate for!

Very practical and easy to use. The best in the whole store. Very many additional modules and a lot of practical knowledge. I recommend
Piter
Very good application and doesn’t take much MB of memory – I had two others but this one is really recommendable

Very useful. Allows you to easily measure the level of light at work and at home and determine its impact on the well-being of our eyes.

I finally know where to put the solar watch for charging, and how to set up my desk lighting. I can see how unevenly lit I’ve been working in so far. Good work!
