Twilight

Struggling to fall asleep after using your phone? Twilight is a mobile utility designed to filter disruptive blue light from your Android screen, based on the theory that such exposure before bed can interfere with natural sleep cycles.

Core Functionality and Customization

The application applies a customizable red tint filter across your device's display. This overlay activates according to a schedule you define, aiming to reduce potential sleep disruption caused by screen use. Users adjust two primary parameters: the color temperature, shifting the screen from a cool blue to a warm amber and red spectrum, and the filter intensity, which controls the darkness and opacity of the overlay. The setup allows for precise calibration to match personal comfort and ambient lighting conditions.

Advanced System-Level Controls

Beyond basic filtering, Twilight offers system integration options for automated operation. These include a launch-on-boot setting, which ensures the filter activates automatically when your device starts. You can configure whether the filter affects the notification and status bar. An optional GPU rendering mode is available for enhanced performance on compatible hardware, with a noted trade-off of potentially higher battery consumption during active use.

Feature Summary

• Adjustable color temperature and intensity
• Scheduled or manual filter activation
• System integration: boot launch and notification control

The app provides a non-invasive, configurable approach to screen dimming for evening use. If you experience difficulty sleeping after using mobile devices, testing this method over a period could yield useful results.
