Add Real-Time Heart Rate Monitoring to Any Site (No App, No Camera, Free API)

Built a heart monitor that works without wearables, camera, or app — just a smartphone on your chest. Powered by real ML, used in 500K+ sessions.

🔍 What’s Inside:

  • 🔥 Why I Built This
  • 🚀 What We Offer
  • 🧪 How It Works
  • 🎯 Ideal Use Cases
  • ⚡ Free API Key

I'm Michal, the founder of HeartScan, a heart-monitoring tool that uses just a smartphone’s built-in accelerometer—no camera, no wearables, no special sensors required.

🔥 Why I Built This

A few years ago, after a stressful business dispute and forced relocation from Minsk to Warsaw, I started experiencing worrying chest pains. Doctors couldn’t provide clear answers, and typical diagnostics were inconclusive.

Frustrated and worried, I used my background in radiophysics and MATLAB to analyze my heart vibrations with my phone’s accelerometer. Shockingly, I discovered extra heartbeats (PVCs) and visualized my heart's valve movements—revealing insights standard methods missed. That moment sparked HeartScan.

Fast-forward: We've now recorded over 500,000 sessions and labeled 7700 hours of real-world heart data, achieving 97%+ accuracy benchmarked against ECG devices.

🚀 What We Offer

We’ve packaged this powerful technology into a simple, lightweight API so you can integrate real heart rate checks directly into your web app or site:

  • Zero hardware costs: Uses existing smartphone accelerometers.
  • Simple setup: Just a few lines of code.
  • High accuracy: ML-powered cardiac phase detection.

1000 free measurements/month for any site or app.

💻 How It Works

Your users simply place their phone on their chest, and in about 10 seconds our API returns their precise heart rate data.
