White Balance Good
For photography white balance, I aim this at my light source, take a kelvin reading, enter it into my camera and viola!, perfect white balance, no need for cards nor discs…I photograph models and get them into magazines.
tolles spielzeug
aber auch nicht mehr. warum sollte diese app mehr können, als die normale ios kamera app? ein weißabgleich kann nicht zu vollständig automatisiert werden, weil es darauf ankommt, was der fotograf ausdrücken will oder um welchen bildbereich es geht.
Great Spectrum Tool
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.

Optical Camera Analysis for FREE
I read the other reviews and noticed poor reviews reflected their phone or camera or lens condition, or user error because it works excellent on my ipad pro! absolute accuracy varies with phone model, camera quality, and by how many times you've dropped or bumped or overheated your phone. roughly estimating, for every 1 meter drop and impact, your phone takes about $100 damage to camera and internal connections. if your phone reports its too hot when its not that hot around it, you've probably smacked it good at some point. it can be repaired by microscope technician but apple doesn't do that, they just exchange phone with a huge exchange price.

Fantastic
Worked well from install but took the time to calibrate by making the spectrograph and now obtain very similar results to others’ Opple-gotten measurements, both for CCT and duv. Very consistent readings too.
I don’t know if it’s possible currently but it would be great to have the app show duv directly to save me calculating it.
Overall very happy with the app, thank you.

Отличное приложение!
Лучшее приложение, если хотите выбрать правильную лампочку без синего пика и не портить себе зрение.
А вообще, возможности приложения очень широкие. Покупайте смело, стоит копейки, а пользы целое море.

Pretty good overall
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.

Super app changez le logo svp 🙏
L’app est génial mais svp changez le logo pour quelque chose de plus pratique comme une roue de couleur ou un simple dégradé froid vers chaud parce que en l’état ce n’est pas pratique pour le retrouver dans les autres applications 🙏🙏🙏 je met directement 5 étoiles si au moins on peux avoir le choix du logo 😁

ブルーライト対策に
安眠を目的として、部屋の照明のブルーライト対策に導入した。白色には青色成分が多く、オレンジ色には青色成分が少ない事が、このアプリで実感できた。
Valide confusing
Tried the app with several leds. Some of them flickering. Here the kelvin values are useless, all about 5000. Without flicker some values are plausible, others not. I don‘t understand the spectrum view, not plausible to me. Recalled the buy.

Over takes my iPhone
Whatever the programming is doing is bad. It takes over the iPhone. I can’t even exit the program, buttons don’t response.
Needs a target on the screen to only measure that point
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!
Great app
This inexpensive app does a great job on my iPhone of measuring light color temperature which is exactly what I wanted!
Quite accurate!
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 need but for film and video it’s pretty great.

Money Back please
This app does not work, gives sane reading what ever the light source !
You should not be charging for an ad pp that doesn’t work..
Rip off…..

Worked well!
I have a flashlight collection with emitters that are color temp calibrated to temperatures such as 2000K, 2700K, 3500K, 4000K, 4500K, 5000K, 5400K, 6000K (and more!).
I found that this app got CCT correct within 100-200K when used properly. I took a white sheet of paper, shined the light on the paper, then read the paper’s reflection. Aiming the app at the flashlight directly gave skewed results by 1000-2000K upwards.
It’s so accurate that I had a light I had mislabeled as 6000K, and it kept coming up as 4950K. I checked the LED bin (XP-L HI V3 3A) and it was actually 5000K! So the 4950K was dead accurate.
I did notice that as you move away from the 4000-6000K range, the ratings are less accurate. For example, my 2700K lights red as almost 3000K, and 2000K lights read as 2700K. My 660nm pure red lamp reads as 2400K. So keep that in mind. But this is a great value for $2!

Overcharged
I was overcharged the amount of $18.38 when I purchased this app. I need a refund and you need to fix this issue.
