Sunrise & Sunset simulation
The sunset simulation dims from 3500K warm white to 1800K deep amber before sleep, triggering melatonin production so your body actually winds down.
The sunrise simulation reverses this sequence before your alarm, priming natural cortisol release so you wake with clarity. Its wake-up light gradually illuminates 5 to 120 minutes before your alarm clock time

One Device. Your Full
Sleep-Wake Cycle Reset.
01
Before sleep
Sunset winds you down
30–60 minutes before your set sleep time, the light gradually shifts from warm white to deep amber. Your body temperature drops, and you start to feel genuinely sleepy.
02
Before wake
Sunrise primes your cortisol
30–90 minutes before your alarm, the light gradually brightens to help you wake naturally. When the alarm sounds, you’re already in a light stage of sleep so you feel clear, not jolted awake.
03
Over time
Your body clock re-anchors
Over time, consistent sunrise and sunset routines can help you fall asleep faster and wake feeling clearer. Within 1–2 weeks, most users report falling asleep faster, waking less groggily, and having more energy through their shifts.

How does CircaRhythm help reset my body clock?
Your body clock runs on light. Shift work feeds it the wrong light at the wrong time, so it stops knowing when to switch off.
CircaRhythm works through the Light & Sound Reset Sequence — a timed sunset that fades the light warm and low while calming sound drops away, and a sunrise that builds light gradually before your alarm sounds. The same signals your body already knows how to read, delivered on your roster instead of the sun's.
Most alarm clocks wake you up. CircaRhythm tells your body when to sleep.
I've already tried melatonin, blackout curtains and white noise. Why would this be different?
Because those fix your environment. None of them tell your body what time it is.
Blackout curtains remove light. A white noise app removes sound. CircaRhythm adds the missing signal — light and sound moving together, gradually, in the direction your body needs to go. That's why it sits alongside what you already own rather than replacing it.
If you've had partial results from everything you've tried so far, this is the piece that wasn't in the room.
Will this actually work if I sleep during the day?
That's exactly who it was built for.
Most sunrise clocks assume you sleep at night and wake in the morning. CircaRhythm assumes nothing. Two independent alarms for early and late starts, a sunrise you can set anywhere from 5 to 120 minutes, a sunset that runs up to two hours or stays on until you stop it, and a display that dims right down — or off completely — for a blacked-out daytime bedroom.
Nurses, paramedics, FIFO, police, aviation and parents of small children. Rotating rosters are the design brief, not an edge case.
How long before I actually feel a difference?
The wind-down usually comes first. Most people notice they're switching off faster within the first few nights, because the sunset gives the nervous system something to follow instead of lying there tired but wired.
Body clock alignment takes longer. Give it a fortnight of consistent use — ideally across a full roster cycle — before you judge it.
That's why the guarantee is 30 nights, not seven. You need a real block of shifts to know.
Do I need to use the app? I don't want another complicated setup.
No. Every function works from the device itself — two knobs, four buttons. Long press to enter a setting, rotate to choose, press to confirm.
The free Smart Life app is there if you'd rather change your alarm from bed or set tomorrow's wake-up while you're still at work. It's optional, there's no subscription, ever, and nothing stops working if you never download it.
Plug it in, set your time, set your sunset. You can be running tonight.
What if it doesn't work for me?
Then send it back.
30 nights, full refund of the purchase price. No interrogation, no hoops. We'd rather you tested it properly across a full roster cycle than kept something that didn't help you.
