Interesting. While it may possible to measure the colour of light in inches, the luminosity is outright silly. I'll have to do something about it. On my phone right now it gets measured in °C which isn't great either.
@becomingwisest A new version 2.8.0 is now available on the App Store, it fixes this bug. The update is rolling out slowly over 7 days but you can update manually in App Store as well.
