Misleading

This is an advert for a colour meter and a spot light meter app. It is not a colour meter.

Great but

Great but one broke they would not replace it so I bought another.
Then that one broke. Very expensive for plastic housing

Best Cine light meter

This is great app, and LuMu hardware is working great (exceptionally precise). I’ve compared it to Sekonic 858d and it’s giving more precise readings in light levels.
Color meter is in par with more expensive professional meters.
Great to see they are back on app store!!

IMPORTANT ISSUE

This is great app, and LuMu hardware is working great (exceptionally precise) however there is a issue with Illumination section in app, specifically when measuring LUX value! It seems that LuMu app shows Lx value as FootCandle. I’ve compared it with Seconic L858d and it’s 10.7 times lower than it should be, which is exactly conversion number for Lx/Fc ratio!
So in conclusion, it’s great, precise tool, just beware that app shows Lx value in Fc.

Wow

Listen, I never write app reviews. I’ve never even thought to write an app review. But this is probably one of the greatest, feature rich apps I’ve ever used in any use case. Not only that, but it’s also so visually pleasing to look at, not to mention super well designed and laid out. Five enthusiastic stars!!
