Works great

I almost didn’t download after reading the reviews. I’m so glad I did. Although this utility uses a back-facing camera, it doesn't take much effort to get a reading. Just point in the general direction — I had no problem seeing the screen at the same time I was checking light quality. If you aren’t getting a reading you expect, tilt the camera a bit one way or the other to grab the light. Easy!

Also, there is a numerical meter that will give more detail than ‘very low’, ‘low’, etc. I have about 150 plants in my home at any given time (for the Farmers Market) and this helps cut out the guesswork.

Excellent Meter

This is a simple, easy to use and straightforward tool for measuring light. It has a very attractive interface and updates to various light levels automatically. I’ve used another meter where you have to push a button to take a reading, but this does it on the fly, which is what I particularly like about it. My only suggestion is that it would be nice if one could use either the front or rear cameras.

Not accurate

I pointed the camera at the leaves of all of the plants in my very bright southwest sunroom. It read anywhere from too low-medium which is by no means accurate. When I hold my phone in front of the leaves but point the camera out towards the light I finally get a reading of bright, which I know the room to be. The room is full of cacti, succulents, and palms- all of which love bright light- and they are all thriving. Clearly there is more than enough light for the room to be considered bright but the app doesn’t read as such. I’m glad it was only $.99 to find out but still a rip off. Save your money.
