Surprisingly accurate on my devices I tested this application against several known color temperature sources and it reported the color temperature/Kelvin within a very small variance to the expected number. Nexus 5 running stock Android 6.0.0 rooted it was consistently within +/-100K. Nexus 7 (2013) stock Android 6.0.0 rooted it was less accurate varying by +/-200K. Samsung S5 Android 5.1 consistent within +/-200K. Surprise results on Amazon Fire Phone FireOS 4.6.3 rooted varying +/-100K.
Very impressed I'm a cinematographer and I bought this recently on a whim just to try it out on a shoot. Its really accurate and straightforward. No crashes so far either
Worth the money I use the Galaxy s. I'm a photographer and through my experience The Calvin readings are exactly right. The only issue I would suggest is no ability to record with flash. Needs some ability to read fash temps. Worth the money!
consistently 1k off I am a professional photographer and color balance is very important to me. I am very disappointed in this device. It is either off by 1k or completely off. I have not had one accurate reading from it yet. I photographed an aquarium last weekend for a client and it was so off...I just shut it down. The aquarium was approaching the 10k range and I knew my camera would have problem(turns out camera read it good or close). This meter on the other hand read right the opposite at 2k. I had some free time today. So I went outside, Texas sunny day, which consistently reads in the 6k area. The meter read it at 4700. clearly to warm. I read it in the shadows and it was 1k to warm. I read it on a gray card and it was to warm. I think the maker could go a long way building in a calibration feature.
Impressive! Working as a Gaffer I use it time to time to check the temp on the lamps if any of them looks suspicious. The app really impreses with the accuracy: +/- 200K but that's totally acceptable. Worth every penny if you don't have colormeter on you. Need to have a trained eye though, to recognize a misreading.
Need to be able to calibrate I downloaded this app and tested it in a television studio where the lighting was set to 2800k using a Sekonic C-500 color meter. The app was at least 1k cooler than the actual color temperature. If you just had a way to calibrate it, it may be of some use..... but currently it is useless.
