A very useful app, I really like it. Different phones will give different readings, so calibrations are needed if you want an accurate number. Pixel 3 and 6 gave si,ilar readings while Galaxy S23's was ~25% lower.

It's great. Thanks to Andrew Huberman for suggesting one of these apps, I'm viewing bright enough light now in the morning and it's helping shift back my sleep schedule

Would really be a nice app, if there would be an effective working calibration method included, not only a factor you can set(by which criteria? ) There should be an calibration process. So without this, on one phone I get in same light situation 6 lux, while on another phone 30 lux, so you can't know the truth. There seems some opportunities for improvement, so unfortunately only not that perfect rating....
