Siddharth Nandyala and Circadian AI: The 14-Year-Old Genius Revolutionizing Heart Disease Detection

In a world where innovation often comes from seasoned experts, a 14-year-old boy from Dallas, Texas, is changing the game. Meet Siddharth Nandyala—a name you’ll likely hear more of in the years to come. With a deep interest in technology and a heart set on solving real-world problems, Siddharth has created something extraordinary: an app called Circadian AI that can detect heart disease in just seven seconds.

Sounds unbelievable? Let’s break it down.

Who Is Siddharth Nandyala?

Siddharth Nandyala isn’t your average teenager. While most kids his age are busy with schoolwork and video games, he’s already making waves in the tech world. Born to Indian parents and currently living in Dallas, Siddharth has quickly risen to global recognition.

He’s officially the world’s youngest AI-certified professional, holding certifications from major organizations like Oracle and ARM. But that’s not all. He also started STEM IT, a platform aimed at encouraging young people to explore science, technology, engineering, and math (STEM) fields.

From early on, Siddharth understood the power of knowledge and how it can be used to make the world a better place. And with Circadian AI, he’s doing just that.

What Is Circadian AI?

Also known as CircadiaV, Circadian AI is a mobile app that uses artificial intelligence to detect heart conditions—just by recording heart sounds. Yes, you read that right. With just a smartphone and seven seconds of recording, the app can analyze the rhythm and pattern of your heartbeats to check for any irregularities.

To use it, you simply place the phone on your chest—specifically on the 5th intercostal space, just under the left nipple. The app records the heart sounds, processes them, and then delivers a quick report. It tells you whether everything sounds fine or if there might be a reason to get checked by a doctor.

This innovation is not just impressive—it’s potentially life-saving.

How Does It Work?

You don’t need fancy equipment or a complicated setup. Circadian AI works using a smartphone’s built-in microphone. When placed correctly on the chest, the phone captures heart sounds. The app then uses trained AI algorithms to pick up on patterns that might signal more than 40 types of heart conditions.

Within seconds, the user receives a diagnostic report. If the app detects anything unusual, it suggests further medical evaluation, like an ECG or an echocardiogram.

While it might seem like magic, it’s all science and smart coding. Siddharth and his team worked tirelessly to train the AI to recognize thousands of heart sound variations. The app is currently intended for use by medical professionals in clinical settings, rather than at home, but that could change in the future.

Is It Really Accurate?

It’s one thing to make a bold claim—it’s another to back it up with data. Circadian AI has been rigorously tested. In the U.S., it was tried on more than 15,000 patients, and in India, around 700 patients took part in clinical trials at renowned hospitals like Guntur Government General Hospital and GGH Vijayawada.

The results? An accuracy rate of over 96% in detecting a wide range of cardiovascular diseases.

Even more reassuring is the fact that patients flagged by the app were referred for further tests, like ECG and 2D echo scans, and the results were later reviewed by qualified cardiologists. In most cases, the app's prediction aligned with the professional diagnoses.

Why Siddharth Built Circadian AI

Like many great innovations, Circadian AI was born from empathy. Siddharth learned that heart disease is the leading cause of death worldwide, accounting for nearly 31% of global deaths. He was struck by how many people suffer due to late diagnoses and limited access to proper healthcare—especially in rural or underserved communities.

That realization sparked an idea: What if he could create a tool that made early diagnosis quicker, easier, and more accessible? Circadian AI was his answer.

By giving doctors a way to screen heart health using just a phone, Siddharth hoped to bridge the gap in medical access and help save lives—especially in places where advanced tools are hard to find.

Recognition and Praise

Siddharth’s invention didn’t go unnoticed. Leaders in the medical and technology sectors have applauded his work, but one of the biggest supporters has been Andhra Pradesh Chief Minister N. Chandrababu Naidu. He praised Circadian AI as a “medical breakthrough” and promised full support for Siddharth’s future projects.

The app is also gaining attention from health professionals, tech investors, and educators around the world. Many are calling it a model for how AI can be responsibly used in healthcare, and a shining example of what young minds can achieve when given the right resources and support.

A Look Into the Development Process

You might assume it took years to build such a complex tool, but Siddharth managed to develop Circadian AI in just seven months. The process involved gathering a wide range of heart sound samples, training the AI model, creating a user-friendly mobile interface, and working with hospitals to conduct real-life trials.

It wasn’t easy. From technical hurdles to getting access to clinical data, there were many challenges along the way. But Siddharth pushed through, driven by his mission to use tech for good.

Inspiring a New Generation of Innovators

What’s truly inspiring about Siddharth is not just what he’s built, but what he stands for. Through STEM IT, he’s encouraging other young people to take an interest in science and technology. He regularly speaks at events and collaborates with schools to promote hands-on learning.

In a world where many students still see STEM subjects as too hard or boring, Siddharth is showing that these skills can be exciting—and even life-changing.

What’s Next for Circadian AI?

Right now, the app is being used in clinical settings, but there’s huge potential for it to be rolled out on a wider scale. Siddharth is already exploring partnerships to bring the technology to more hospitals, clinics, and even schools.

There’s also interest in adapting the app for at-home use, which could be a game-changer for preventive healthcare. With just a phone, people in remote areas could monitor their heart health without needing to travel miles for a check-up.

In the long term, Siddharth hopes to expand Circadian AI to detect other medical conditions too, using similar sound-based diagnostics.

Final Thoughts

Siddharth Nandyala isn’t just a tech whiz—he’s a reminder that age is no barrier when it comes to solving big problems. Through Circadian AI, he’s blending technology, compassion, and ambition in a way that could change lives across the globe.

As healthcare continues to evolve, it’s innovations like this that show us the future is already here—and sometimes, it’s being built by the youngest among us.
