Chest pain?
Know if it's your heart.

Early heart attack detection for people at home and at work. Our ECG monitor and biomarker patch check your heart, and your phone tells you when it's serious. One-tap SOS if you need help fast.

The problem

Is it a pulled muscle, or a heart attack?

Chest pain at home or in the office is confusing. A strained muscle, acidity and a heart attack can feel alike. Many people wait and hope it passes, and lose the time that matters most.

Muscle pain

Heart signals look normal

Steady ECG, heart attack markers low. The app tells you your heart signals look normal, and to keep an eye on how you feel.

or
Heart attack warning

Heart signals are changing

ECG shows heart attack signs, markers rising. You get an urgent alert on your phone, with one-tap SOS for the nearest ambulance.

If your pain is severe or you're unsure, always call for emergency help. CardiosensAI does not replace a doctor.

20.5Mpeople die from heart disease every year. It is the world's leading cause of death.
4.7M+deaths a year in India, about 28% of all deaths in the country.
75%of rural and small-town areas lack advanced heart testing nearby.

How it works

Two devices. One app on your phone.

The ECG monitor and the biomarker patch work separately. Each sends its results to the CardiosensAI app on your phone. Alerts come to you first, so you can act early.

Part 1 of 6 · Two devices

CardiosensAI has two wearable devices that work separately: an ECG monitor for the heart's rhythm, and a patch that checks for heart attack markers.

Device 1

ECG monitor

Records the heart's electrical signal, beat by beat, day and night.

Device 2 · In development

Biomarker patch

Checks for heart attack markers through the skin, with no needle or lab wait.

Our AI · being tested

AI that reads every beat

Our machine-learning model checks the ECG for many kinds of heart problems.

Emergency

One-tap SOS

In an emergency, press SOS in the app. It contacts the nearest health centre's ambulance service and shows you the nearest hospital, with directions.

Part 1 of 7 · Normal

A normal heartbeat: a steady rhythm and a regular shape. No alert is needed.

Our AI

What our AI spots in an ECG

Our model is trained to find many kinds of heart problems in ECG data, including:

  • Irregular rhythm (AFib)
  • Heartbeat too fast or too slow
  • Extra beats (PVCs, PACs)
  • Bundle branch blocks (RBBB, LBBB)
  • Signs of a heart attack
  • Many other abnormalities

The app does not replace a doctor. It tells you when you should get checked.

Why it matters

In a heart attack, every minute counts.

01

Chest pain is confusing

A strained muscle, acidity and a heart attack can feel very similar.

02

People wait and see

Unsure what the pain means, many people delay getting help, and precious time is lost.

03

Some heart attacks are silent

Many people, especially those with diabetes, feel no chest pain at all.

Part 1 of 3 · Today

Chest pain starts at home or at work. Is it just a muscle? With no way to know, many people wait and see, and hours can be lost.

Who it helps

Wherever chest pain catches you.

At home

Chest pain at night?

Check your heart without leaving home, and know whether it's something serious.

  • Round-the-clock heart monitoring
  • Alerts straight to your phone
  • Peace of mind for you and your family
At the office

Stress, long hours, sudden pain

Know if it's your heart before you decide what to do next.

  • Discreet to wear during the workday
  • Helps tell harmless pain from heart warning signs
  • No need to guess
In an emergency

Help, one tap away

One tap on SOS contacts the nearest health centre's ambulance service and shows the nearest hospital.

  • Calls the nearest ambulance service
  • Shows the way to the nearest hospital
  • ECG report ready for the emergency team

Our progress

Proof first, then launch.

A medical device has to be tested carefully before anyone relies on it. Here is where we are, and what comes next.

  1. 2025–2026Now

    Building the basics

    Building the ECG monitor and its AI, and developing the biomarker patch in the lab.

  2. 2026–2027Next

    Full prototypes

    Wearable versions of both devices, accuracy testing, and first clinical studies with ethics approval.

  3. 2027–2028Planned

    Clinical trials

    Large clinical trials. Applying for approval in India, the UK and the UAE.

  4. 2028+Future

    Into homes & workplaces

    Launching for people at home and at work, with the app and one-tap SOS.

Our promise: every result will be checked against standard medical ECGs and lab blood tests before we make any claim.
