[ROOT] Night Light (KCAL)

About [ROOT] Night Light (KCAL)

Night Light (KCAL) adjusts the intensity of blue light in the display using KCAL color controls. Users can adjust color intensity directly, create display profiles, and apply a profile with one action. Automation features can apply settings over time, and a Tasker plugin integration is listed. The app is intended for devices whose kernel supports KCAL, the Android kernel interface used for these display color adjustments. The app requires root access as well as a compatible kernel, so it cannot perform its main function on an ordinary unrooted device. It can use location information to determine local sunrise and sunset times for automation. The evidence says location is used for that purpose and is not shared; internet access may be used to estimate location when an exact location is unavailable. Night Light provides display color controls and scheduling for users with the required device setup. The supplied description makes a claim about comfort and falling asleep, but does not establish a health benefit, so the app should be understood as a display adjustment tool. Compatibility depends on the phone’s kernel and root configuration, and those requirements are central to whether it can work.
