Could this 14-year-old’s app save your life? Instantly detect early heart failure in just 7 seconds
- Replies 0
Imagine a world where a simple smartphone app could listen to your heartbeat and, in just seven seconds, alert you to early signs of heart trouble—before you even feel a symptom.
It sounds like something out of a futuristic medical drama, but thanks to the ingenuity of a Texas teenager, that world is already here.
Meet Siddarth Nandyala, a 14-year-old prodigy from Frisco, Texas, whose passion for technology and helping others has led to the creation of Circadian AI—a groundbreaking app that could change the way we detect heart disease.
And yes, you read that right: he’s only 14, but his invention is already making waves in the medical community.
How Does It Work? The Science Behind the Magic
Circadian AI is more than just another health app.
By simply placing your smartphone near your chest, the app records your heart sounds, filters out background noise, and sends the data to a powerful cloud-based artificial intelligence model. In a matter of seconds, it analyzes the rhythm and quality of your heartbeat, searching for telltale signs of trouble.

What can it detect? The list is impressive: arrhythmias (irregular heartbeats), early signs of heart failure, indicators of coronary artery disease, and even heart valve abnormalities.
In other words, it’s like having a mini-cardiologist in your pocket—one that never takes a day off.
A Young Innovator with a Big Mission
Siddarth’s journey began with a simple question: How can artificial intelligence make a real difference in people’s lives?
Inspired by the potential to save lives, he spent months gathering heart sound data from hospitals in both the US and India.

He worked closely with doctors, nurses, and patients, refining his app until it could reliably spot the subtle clues that even trained professionals might miss.
The results speak for themselves. In clinical trials involving nearly 19,000 patients across two continents, Circadian AI achieved an astonishing 96% accuracy rate in detecting heart abnormalities. That’s not just impressive—it’s potentially life-saving.

Not a Replacement, But a Powerful Tool
It’s important to note that Circadian AI isn’t meant to replace traditional diagnostic tools like EKGs or echocardiograms.
Instead, it serves as a pre-screening tool for trained medical personnel, helping them quickly identify patients who may need further testing. In areas where access to healthcare is limited, this kind of technology could be a game-changer.
As Dr. Jameel Ahmed, an electrophysiologist at Louisiana State University, put it: “An early potential diagnosis in patients who otherwise may not have had access to medical care may ultimately reduce long-term morbidity and mortality from this condition.”
A Track Record of Innovation
Siddarth’s achievements don’t stop with Circadian AI. He previously designed a low-cost prosthetic arm and founded STEM IT, a startup that creates science and technology kits for students.

His work has earned him recognition from the US House of Representatives and even a congratulatory letter from President Joe Biden. And if that’s not enough, he’s already a freshman studying computer science at the University of Texas—at just 14 years old!
Looking ahead, Siddarth hopes to expand his app’s capabilities to detect lung conditions like pneumonia and pulmonary embolism, using similar sound analysis techniques. His vision?
To inspire a new generation of inventors and innovators to push boundaries and make the world a better place.

The app was developed with input from doctors and patients, and clinical trials with nearly 20,000 patients showed over 96% accuracy in identifying heart abnormalities. Image source: Republic World / Youtube.
