Fulmine Software/Night Mode

The Night Mode app filters out blue light, which according to recent research studies increases alertness and can affect your natural sleep and awake cycles (circadian rhythm). In addition, it precisely controls the screen's color temperature to provide the most soothing and relaxing lighting.

When using your device at night or in twilight, even minimum screen brightness may tire your eyes. Switch to Night Mode to activate additional screen brightness reduction through a dedicated dim filter as well as through the main blue light filter.

If you sleep next to another person or use your device in places where screen light may disturb others, then this app is for you.

If you are a night owl who use your mobile in bed for Internet browsing or reading, this app can prevent the screen from turning off, and lock screen rotation to any desired orientation, even upside down.

Just shake your device to enter Night Mode and vice versa. It's an optional feature switched on/off in the app settings.

For Nougat users it's possible to add Quick Settings Tile to quickly shift to Night Mode.
