Circadian Display

Circadian Display continuously adjusts your screen's warmth and brightness throughout the evening based on customizable curves you define. Unlike standard night light solutions with fixed on/off schedules, Circadian Display provides a smooth, gradual transition tailored to your preferences. Features: - Dynamic comfort curves with precise warmth and dimming levels over time - Dual-engine modes: Native (system-level, Android 10+ with ADB setup) and Overlay (software-based, works on all devices) - Background scheduler for automatic, hands-free operation - Privacy-first: completely offline, tracker-free, no data collection - Open source (Apache 2.0)
