A true story
This is Sabi.She felt perfectly fine.Four months later, she woke up almost blind.
Her story is real. You'll find all of it below.It didn't start with the hospital. It started with mornings like these.
Who it's for
Sound familiar?
Tick what sounds like you.
No matter how much I sleep, I wake up tired.
My head never switches off.
I'm doing everything right, and I can't tell if it's working.
Before my period, my mood and energy crash.
Why it matters
You feel fine. Until one day you don't.
Poor sleep, stress and running on empty build quietly. One ordinary morning at a time.
What your dots are really about.
HRV and breathing when the signal is clear.Sleep

Illustrated, in Sabi's voice: how she felt in her months before.
Ten years of creeping up.Almost double the risk.
the risk of dying from heart disease when resting heart rate crept from under 70 to over 85 in about 10 years, versus staying under 70.
Every 10 beats counts.The risk climbs with each step.
higher risk of dying for every 10 extra beats a minute at rest
A heart that ticks like a clockis not a good sign.
the risk of a first heart attack, stroke or similar event with the lowest HRV

Heart rate accuracy
Your phone camera matches a Google Fitbit Air.
We measured heart rate 150 times with moonScan while wearing a Google Fitbit Air. On average, the two were just 1.4 bpm apart.

Why not a wearable?
Nothing to wear. Nothing to charge.
A ring, band or watch only works if you buy it, charge it and wear it every night. moonScan works with the phone already in your pocket.

| moonScan | What matters to you | Apple Watch, Oura, WHOOP, Fitbit |
|---|---|---|
| Sleep with nothing on you | Your nights | Worn all night, every night |
| Nothing new to charge | Charging | Flat battery, lost night |
| Scan in the next minute | Getting started | Order, wait for delivery, pair |
| Come as app updates, in your plan | New features | Often need a newer device |
To be fair: wearables also track sleep stages and your activity through the day. moonScan reads heart rate, HRV and breathing in one morning scan.

Why we built it
It started in a hospital room.
Sabi, my fiancée, nearly lost her vision after a severe inflammatory attack.
For months, her body was struggling. We weren't looking.
BeforeI feel perfectly fine.
Month 1Stress
It's just a busy stretch at work. I'll rest at the weekend.
Month 2Panic attacks
My heart was racing again last night, out of nowhere.
Month 3Always tired
I slept nine hours and still woke up exhausted.
Month 4
Then one morning, she woke up almost blind.I'm fine. I just need a holiday.
HospitalRecovery
We started with the simplest thing: her sleep.
Today, healthy againA note from Viktor
Seeing Sabi in that hospital bed changed how I think about health.
Her recovery is where moonlight began again. Now we want to help you understand your body, one morning at a time.
That’s why we built moonScan. So your mornings don’t go unseen.
Viktor Bánczi, founderIllustration. We never measured those mornings, so we can't know what they would have shown. Sabi's words are illustrative, not exact quotes.
moonScan is a wellness tool. It does not diagnose or prevent illness.
The science
Your heartbeat shows in your face.
Your eyes can't see it. A camera can. It's called rPPG.
- Find the skinForehead and cheeks are tracked in every frame.
- Read the colourEach beat shifts skin colour, most clearly in green light. [1]
- Remove the noiseFilters drop light flicker and small movements. [3][4]
- Time the beatsThe time between beats gives heart rate and HRV.
Heart rate62 bpm
