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.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Your whole day, as one dial.
Your wake time sits on the left of the horizon line and your dim time sits on the right, because your dim time is your sunset. The morning light window and the wind down stretch are now drawn to scale, so an hour looks like an hour and the melatonin estimate looks like the estimate it is.
Also in this release:
Fixed a bug that could blank the Lock Screen when a timer finished.
Onboarding now works at every text size, and can no longer be dismissed without setting a wake time.
Reset CivilDusk now clears everything it says it does, including your alarm and any schedule on your home hub.
The Manual and Automatic switch on the Rhythm screen is readable again, and it no longer says Automatic when your home hub rejected the schedule.
Still no account, no ads, and no sleep score.
