Light brightness (LUX or LUMENS) and Light Temperature (Frequency) readings match an older light meter I used for film photography. The accuracy of the app depends on the phone used. On my Pixel 3a it stunk. With my Samsung Galaxy it was very accurate. Great app. Light temperature is not a reading of heat, its a reading of frequency. This not a Spot meter. If you want a spot meter buy an old Weston Spot Meter.

Rated this only because it seems the app is using the front sensors which are very limited when compared to the back. Would be great if it could utilise the rear XZs sensors, I will continue using the Android test menu for now but great effort

Decent app. Nice UI. Two issues. 1) Meter uses front-facing camera. Need to be able to use rear camera so phone can be aimed at light source while being able to see the screen. 2) Color temperature is off by a factor of 10 - example, 5000K daylight is displaying as 500K. Need to add a zero at the end.
