This 14-Year-Old Is Using a Smartphone and AI to Detect Heart Disease in Seconds

While most teens are juggling homework and hobbies, one young innovator has taken a giant step into the world of healthcare and artificial intelligence.

At just 14, this Indian-American teen Siddarth Nandyala has built something extraordinary: an app that listens to your heart and helps detect early signs of heart disease in just seconds. No expensive machines. No hospital visits. Just a smartphone and AI.

How Does It Work?

The app, called Circadian AI, is a simple but powerful tool. It uses your phone’s microphone to record heart sounds, then runs them through an AI model that can detect signs of cardiac issues.

It’s:

• 🎧 Non-invasive

• ⚙️ AI-driven

• 📱 Smartphone-based

• 💯 Over 96% accurate

The AI has been trained using heart data from 15,000+ patients in the U.S. and 700+ patients in India — making it both smart and reliable.

Tested and Trusted

This isn’t a science fair project — it’s real.
The app has been tested at the Guntur Government General Hospital in Andhra Pradesh, where doctors were impressed with its speed, accuracy, and potential to transform rural healthcare.

It’s especially useful in areas where expensive equipment and trained specialists are in short supply.

🏅 Big Praise from Big Names

The young creator’s work has been praised around the world, including:

• Former U.S. Presidents Barack Obama and Joe Biden

• Andhra Pradesh Chief Minister Chandrababu Naidu, who called it a "medical breakthrough"

In a personal meeting, the Chief Minister encouraged him to scale the solution and highlighted how this kind of innovation can shape India’s healthcare future.

What’s even more amazing?
This isn’t about fame or fortune. It’s about access. The goal is to bring life-saving AI tools to rural clinics, schools, and health camps, helping catch heart issues early and save thousands of lives.

This story is more than just one app or one teenager.
It shows how artificial intelligence can make healthcare smarter, faster, and fairer — and how the next generation is already taking charge.

From heart health to cancer detection, AI is becoming the doctor’s new best friend — and kids like this are showing us the way.
