Health that lives on your phone
Thirty seconds, wherever you are. A steady selfie reads your heart rate. A voice note in any language tells Pulse how you are doing. The air around you joins the same moment. After a week or two, your Pulse shows you patterns the clinic does not usually get to see.

Three things our phones get wrong about health
On the day your chest tightened, the pollution hit 180 micrograms. Your watch logged a workout. Nobody put the two together. Different apps, different timelines, no story.
What Pulse does
A Pulse keeps all three on the same moment. Your body, the air around you, and what you say in your own words. The three sit together, the way you actually live.
You see your clinician and they ask how you have been. You guess. The rough nights, the pollen days, the morning your kid coughed. All gone by the time you sit down.
What Pulse does
A week of Pulses adds up to a Signature: the pattern of how your body responds over time. The chart the clinic does not usually get to see.
A free translator mixes up pain location and severity. The interpreter you cannot afford speaks a different dialect. The leaflet on the wall is in a language you do not read.
What Pulse does
Pulse listens in seventy-plus languages and arrives at the clinic in the doctor's. Your own words are kept beside it; nothing is paraphrased away.
What is in a Pulse
Hold a steady selfie for thirty seconds. Pulse reads your heart rate from the gentle colour shifts in your face — the same technique a clinic uses, just from the camera you already have. Works best in good light. Please do not use this in an emergency.
The same moment includes the air at your location: PM2.5, pollen, ozone, UV. The bit nobody else captures, paired with your body on the same timeline. So when your chest feels tight, you can see whether the day around you was tight too.
Tell Pulse what is going on. Hands free, in any of seventy-plus languages. We turn it into a short clinical-shaped note your doctor can read in a few seconds. Your own words are kept beside it; nothing is reworded away.
What Pulse is good for
Open Pulse and have a sixty-second call. The app listens, your camera reads your heart rate, the air around you joins in. At the end your Pulse is saved.
A real conversation, no forms to fill in
A small seal goes on every Pulse the second you finish it, so a clinic can see that the reading on the QR is the exact one you took, nothing edited later.
Like a tamper-evident sticker on a bottle
Cabin pressure, rural clinic, bus through a tunnel. Take a Pulse anyway. It signs on your phone and uploads itself when you reconnect.
Take it now, sync it later
You share a QR with a doctor, a clinic, a family member. They open it on their phone, no Pulse login, no portal, no app store. Same trick as a COVID card.
Open the QR, read the Pulse
After a couple of weeks your Pulses add up to a Signature. The patterns get written against public health advice, with the source linked, so the words mean what doctors mean.
No vibes, sources you can click
A five-minute listen lands in your inbox each weekend. Your Pulses, your patterns, what stood out. Made for you, listen on the way to brunch.
Five minutes by email, every Sunday
Why Pulse
A lot of health apps assume you are a thirty-five-year-old fitness influencer with an Apple Watch. Pulse works just as well for a refugee mum in Berlin, a granddad in rural Phitsanulok, or a carer juggling kids and ageing parents. Seventy-plus languages of voice. Runs on a basic Android. No band to buy.
Apple Health knows your steps. Air-quality apps know the pollution. Symptom trackers know what you typed. Nobody puts the three on the same moment. Pulse does. After a few check-ins, a pattern shows up — like how your heart rate runs a little hot on bad-air days. That pattern is the chart your doctor wishes they had.
WHOOP wants €239 and €35 a month. Apple Watch is €400 and up. Function Health is €499 a year just for labs. Pulse is whatever phone you already have. Five Pulses free every month, forever. If you want a family timeline and unlimited check-ins, that is €9.99.
Clinical pilots
Pulse is being prepared for pilot deployment with paediatric pulmonology teams and community-health programmes in environments where families face high respiratory exposure or fragmented care: wildfire smoke, agricultural burning, refugee resettlement, rural distance from specialists.
Clinical advisors include practicing paediatricians in EU and Asia-Pacific care settings. The product launches as an informational digital health companion; clinical-device certification is a separate, longer track.
Stack
Sharing with your clinic
A Pulse is small enough to send as a link, a QR code, or a downloadable card. Your doctor opens it and sees the whole moment in one place: your heart rate, the air you were breathing, what you said in your own words. We sign each Pulse so a clinic that wants to confirm nothing was edited can do so with a free verifier app — but most just read it. The signature is there for the ones who ask.
