TEENAGER BUILDS APP THAT BEATS HEART SURGEONS AT THEIR OWN GAME
Meet Siddharth — age 14, armed with machine learning, and apparently here to disrupt cardiology before getting his learner’s permit.
His app can detect up to 40 heart conditions in seconds, using ECG data and… https://t.co/Nu7eC2l16K pic.twitter.com/UCEjLerM19

A 14-year-old prodigy has stunned the medical world with an AI-powered app that detects heart disease in seconds—outperforming seasoned heart surgeons by a wide margin. Siddharth Nandyala, an Indian-American teen based in Dallas, developed Circadian AI, a revolutionary tool that analyzes heart sound recordings and delivers near-instant diagnoses with an astonishing 96% accuracy rate. Doctors, by comparison, achieve only 54% accuracy in similar screenings.
The app works by using a smartphone’s microphone to capture heartbeats, which are then processed through advanced machine learning algorithms. Within seven seconds, Circadian AI flags potential cardiovascular issues, offering a level of speed and precision that traditional diagnostic methods struggle to match. This is not just an improvement—it is a complete transformation of early heart disease detection.
The technology has already been tested on over 15,000 patients in the U.S. and 700 more in India, passing rigorous clinical evaluations at the Government General Hospital in Guntur, India. The results have been so impressive that the app has earned praise from former U.S. Presidents Barack Obama and Joe Biden, as well as Andhra Pradesh Chief Minister N. Chandrababu Naidu. When world leaders take notice, you know the innovation is groundbreaking.
Siddharth, recognized as the world’s youngest AI-certified professional with credentials from Oracle and ARM, says his goal is to make heart disease detection accessible to everyone. “Early diagnosis is the difference between life or death,” he explained at the Global Artificial Intelligence Summit in Hyderabad. This is not just about technology—it is about saving lives.
The implications of Circadian AI are enormous. Millions of people in remote or underserved areas lack access to advanced medical screenings. With this app, a simple smartphone could become a life-saving diagnostic tool, eliminating the need for expensive equipment and lengthy hospital visits. This is the kind of innovation that disrupts industries and forces the medical establishment to rethink its approach.
Despite its success, Siddharth remains focused on improving the app further. He is currently pursuing a Bachelor of Science in Computer Science at the University of Texas at Dallas, proving that age is no barrier to changing the world. While most teens are navigating high school, Siddharth is reshaping the future of healthcare.
The medical community is now watching closely. If Circadian AI continues to prove its effectiveness, it could become a standard tool in hospitals worldwide. The question is no longer whether AI can outperform human doctors—it is how quickly the industry will adapt to this new reality.
