Light in the morning. Wind down at night. CivilDusk times the two habits sleep science agrees on - from your own wake time, with no account, no ads, and no sleep score.
YOUR RHYTHM, THREE MOMENTS
- Wake: set it once, or let it follow your recent sleep from Apple Health. Everything else is timed from it.
- Morning Light: 10 to 30 bright minutes soon after waking anchors your energy and tonight's sleepiness. Get a gentle nudge, or run it hands-off.
- Wind-Down: a calm evening window - dim, wind down, bed - built from your target sleep and shown as an estimate, never a measurement.
A REAL WAKE-UP SEQUENCE
- Sunrise light that ramps up and ends at your wake time.
- A real alarm at the top - snooze or slide to stop, like the Clock app.
- Edit the order and degree: ramp length, peak brightness, alarm on or off.
WORKS WITH YOUR LIGHTS
- Wi-Fi bulbs, including older bulbs that never worked with a smart-home hub - scan your network and control them directly. No bulb account, no cloud.
- HomeKit and Matter lights run the schedule automatically on your home hub while you sleep, no app open.
- Manual control too: on and off, brightness, color - with recommended morning and evening colors.
ON YOUR LOCK SCREEN
- Timers run as Live Activities on the Lock Screen and Dynamic Island, with a stop button right there.
- Start Morning Light or Wind-Down with Siri and Shortcuts.
PRIVATE BY DESIGN
- No account. No ads. No sleep score.
- Nothing about you leaves your phone. Health sleep data is read-only and optional.
- The only networking is local control of your own lights.
CivilDusk is free. It shows estimates based on your schedule - it does not measure or diagnose anything, and it is not a medical device.
