Android is Now Easy on the Eyes
Flux, a popular resource on the desktop, is coming to Android.
The app, which has previously been available to Mac, Windows, Linux and iOS users, controls the "color" temperature of a screen in order to reduce eye strain, changing as the day progresses.
Flux essentially just removes the bright blue colors from the display as it gets later in the day. By the next morning, it’ll have returned to normal for your regular daytime viewing.
Right now Flux requires a rooted phone to work properly and the company says that many Samsung Galaxy devices running Android 5.0 or higher won’t work, rooted or not.
