buggy, predatory and not very accurate. not sure where these professionals are getting their equipment that only match this app, likely they are comparing to recycled paint swatches found in a dumpster. There are free alternatives that do just as good a job or better, it's a toy.

Full of ads, everywhere, every time. This app has functions which do not work as per their claim. I am extremely dissatisfied. Not recommended. One last thing, if it works, it shows the wrong color temperature. I tried to measure the color temperature of a newly purchased Philips LED bulb with an advertised color temperature at 2700K, this app detected as 5250K. That is too far from accurate.

Sorry! Did you direct the camera of your Vivo phone towards a white paper illuminated only by the light source you tried to measure? I do not understand what you are saying about full of ads, as there have never been any ads in this app. Feel free to write directly to me at
[email protected] if you want. Thank you Hitendrakummar!

Accurate without calibration on my Samsung Flip 5. I had a 5600K photo light box and the app instantly read it as 5600K. I am using it to dial in proper white temperature on a projector setup. Excellent so far, thanks Bjorn!

Thanks so much for confirming its accuracy! It's great to hear it matched your 5600K light box perfectly. Thank you!

I am a color matcher and I compared my new X-Rite Spectralight QC lightbox on D65 and this app nailed it as 6500 K. I'll be using this app frequently dealing with our customers.

Very good app to see what your LED flashlights emit. My test was a Sofirn IF23PRO. Sidelight can be set from warm to cool. (750 lumens) Warm end is 3400k, cool end is 5800k. I normally leave it at around 5000k for better CRI. Checking main emitter between flashlights can show how far onto the blue it is, or if it's more neutral.
