Twilight: Blue light filter

Warm the screen after dark

Twilight: Blue light filter changes your Android screen from a cooler blue tone to a warmer red tone as evening arrives. It is suited to people who read, watch videos, or use their phone late at night and want less harsh light without adjusting the display by hand each day. The schedule can follow local sunset and sunrise times, making the filter automatic rather than a nightly task.

Controls for low-light use

Alongside colour temperature, Twilight can reduce screen brightness below the phone’s usual minimum. That is useful for reading in a dark room, where even the lowest standard brightness may feel too strong. Sliders let you set the warmth and dimming level, while a quick control can pause the filter when accurate screen colours matter, such as in a photo-editing app.

Fits into a sleep routine

The app is aimed at evening screen habits rather than general fitness tracking. Its purpose is to make late use more comfortable and reduce the amount of blue-toned light reaching your eyes before bed. Wear OS controls and Philips Hue support can extend the same wind-down routine to a watch or compatible home lighting, where those devices are available.

Twilight is a practical choice for users who want scheduled screen warmth, deeper dimming, and the option to leave selected apps unaffected. It offers more control than the standard brightness slider while keeping its main job focused: making a phone screen gentler to use after sunset.
