Ratings and reviews

Seems to work well. It's very easy to use. I haven't checked it against a professional meter, but it's relatively close based on my experience. It does have a calibration factor that can be adjusted to match a calibrated light meter. For those who think it is using the wrong side of the phone to measure, you need to look up the difference between incident and reflected light meters. Incident measures the actual light strength. Reflected measures the light after is is reflected off an object.

One of the best lux meter you can find on the store. It's simple and has everything you need, circular meter and linear chart. It would be nice if it has a lumen calculation because people try to use these kind of apps to measure the luminance without spending a fortune for a dedicated lumen meter. If developer can add that feature it is worth 5 stars. In fact is worth 5 stars as it is but I fell that is missing something.

You get what you pay for! Passes the "look test". It has a clean, well set up screen and scrolling graph. But why do they use the front camera (selfie) for getting their data. The rear (main) camera could get data by aiming at the source without you in the way. It would also be better if you could adjust the graph timeline and have it output to somewhere. But for a free app it is good.
