habe die Messwerte der App mit denen eines geeichten Lichtmessgerätes verglichen, die Genauigkeit der App liegt oftmals bei nicht einmal 50%. Damit kann man die Lichtstärke nicht messen. Von der Bedienung her ist die App in Ordnung, daher gibts auch einen von fünf Sterne.

I just use a light meter for plants, and for that it's excellent. It need not be perfectly accurate for me, and it's great for comparing the available light under lights and in windows as the days get shorter and the sun gets weaker.

Have used many times and great for a quick measurement when you don’t need full field equipment.

My I phone has a front and back side camera. I have a screen protector on the face that affects the readings. I make sure I use the back side camera for most accurate results with this app. Can’t speak to accuracy compared to a standard. This app works great for my needs.

Exactly what I needed to confirm my plan for a tropical paradise escape bathroom!

It’s totally possible that I’m using it wrong, but since there’s no instructions, I don’t know how else to do it. It seems pretty arbitrary, like I’ll hold it up to one spot and it will give me a light range from like 18 fcs to 2,000 fcs so idk.

Tried it with Iphone 11 and compared to a professional lux meter. The readings are off by an order of magnitude (about 8 times)! It is unclear how the developer could have “calibrated” the app when it is so grossly inaccurate. Deleting it...

Electronic testing. Accurate, easy to use. Simply the best.

As an investigator of tripping injury accidents, the ability to get a light intensity reading with my phone cuts down on a lot of equipment to lug onto a job site. Love this app.
