LightSpectrum Pro App Reviews

This is an amazing application. You did a phenomenal job, thank you!

I was looking for an app to measure color temp without external hardware. I found this after trying several others and was very pleased.

Some old-fashioned people think that a quality program should have no misspellings. So think about ‘cancel’ and ‘wavelength’, please. Aren’t you embarrassed by these errors?

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.

Just got this app and held it under our Halogen and LED lights and our LED grow-light. This app is sensitive: the grow light has rows of different color LED and as I moved my iPhone the data changed with small moves. I think it will work great. And I love that there are no (that I’ve discovered) additional in-app purchases like so many apps have nowadays.

I used to use a $2,000 light meter to measure color temperature when I worked in the film industry. This meter costs only a few bucks and is almost as good. The app description says it’s within 8% of the actual color temperature, which in most circumstances is sufficient. I tested the app in a variety of environments; I.e. outdoor sunny, outdoor cloudy, interior lights, balanced to daylight, cool white, etc. and it worked great. If you’re doing scientific measurements it might not be what you ne

This inexpensive app does a great job on my iPhone of measuring light color temperature which is exactly what I wanted!

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!
