LightSpectrum Pro

Аффтор, обнови прогу, чушь показывает.

Ничего не понятно, что не измеряй везде одинаковые показания, причём шкала, совершенно не верная

I have no experience with professional equipment in this area but this app I like a lot. I have it some time now and use it to look at color temp of light sources and especially the blue color component. Although my very 1st experience was not very good, app crashes/freezes, I must say that past years (2020/2021) the app has become a lot more reliable and stable. Last time I checked there was no other app that has the functionality offered by this app. The UID maybe can be better but after some practice its not that difficult to work with.

The interface is somewhat strange, but it’s workable. The lux and kelvin values seem accurate, but on my phone (iphone 12 pro max), you have to keep the phone pointing dead straight at the source. So i’d say it’s fine for hobby purposes.

Very low quality and not accurate at all. Even you can’t get a basic estimation about the light conditions. More than that, its user interface is a disaster. I payed the price for purchasing and tested it on iPhone 6s, Ios 13.3.1

This apps work great with iOS 7. Very easy to use and it can give you a lot of information. Just tap on the screen and it will give you the temperature in Kelvin. I don’t know how accurate it is, but first impression is good.

This App does not work at all.

Absolutely not working. As a video profesional I Would love to have an app that could give me the color temp of a light source. Unfortunately this app doesn't work at all. Doesn't even activate camera. iPhone 5 (MD622DN) iOS 6.0 (10A405)

I have some LEDs where I know the wavelengths, and under some combination lighting conditions the app is super inaccurate—but under lots of conditions (including combination ones) it’s very accurate. Useful tool, overall. I wish they would fix the inaccuracies but I’m still glad I have this app; there’s no other app that has a full spectrogram right now.

This app needs to have crosshairs or circle at a point on the screen, to only take measurements. General averages of the picture isn’t a great feature. Spot metering will make this app awesome!
