Sundown Sleep Light

Sundown turns your iPhone into a quiet bedside sunset light. Tap Start and the room eases from warm evening light, through orange and deep red, into darkness — using only the hardware already in your phone. Two light sources work together: the rear light bounces a soft glow off a nearby wall, and the screen shows a warm color that dims to a deep-red afterglow. - One-action daily use: open the app and tap Start Sundown. - Choose a length from 1 to 120 minutes. - Reveal temporary controls with a tap: time remaining, +10 minutes, Brighter, or End. - Calibrate the wall glow and screen glow once to fit your room. - Optional local bedtime reminder that your sunset is ready. - Sundown Pro (one-time): start with Shortcuts & Siri, custom sunset profiles, custom extension length, time-of-day or surrounding-light calibration, and dimming one HomeKit room light along with the sunset. - Works entirely on your device. No account, no tracking, no data collection. Sundown is a light, not a sleep tracker or medical device.
