In a world where heart disease continues to be one of the leading causes of death, a teenager from Frisco, Texas is stepping up in a way no one saw coming. Siddarth Nandyala, just 14 years old, has created a revolutionary smartphone app named Circadian AI that’s capable of detecting early signs of heart disease... in just seven seconds.
Sounds like science fiction? It's not.
What Exactly Is Circadian AI?
Circadian AI is a machine learning-powered app designed to analyze heart sounds using a smartphone’s microphone. When a user records the sound of their heartbeat, the app’s algorithm goes to work... and within seconds, it can flag early signs of abnormalities that could be linked to heart disease.
This isn’t just some school science project. Siddarth's app has already been tested on nearly 18,500 patients across the United States and India, achieving an impressive 96% accuracy rate in identifying heart issues.
Yes, 96%.
How Did He Do It?
Many wonder... how can a teenager outperform billion-dollar companies in medical tech?
It started when Siddarth’s grandmother fell ill due to heart complications. Frustrated by how long diagnosis took, Siddarth began researching cardiac health. He dove into medical journals, taught himself about machine learning, and began training models using publicly available heart sound datasets.
What he lacked in funding, he made up in dedication. After endless nights of coding, failing, and refining, Circadian AI was born.
Currently, the app is intended for use by trained professionals in clinical settings... but Siddarth has bigger dreams.
What’s Next for Circadian AI?
Siddarth is now a computer science freshman at UT Austin, balancing college life while running his own STEM startup. But he’s not stopping at hearts. His goal is to adapt Circadian AI’s technology to detect lung diseases next — a move that could disrupt pulmonary diagnostics worldwide.
What’s even more impressive is that Siddarth isn’t just developing tech. He’s also campaigning for increased youth involvement in STEM, speaking at events, and mentoring other aspiring teen innovators.
Why This Matters for the Rest of Us
Heart disease often has no symptoms until it’s too late. Early detection saves lives... yet access to diagnostic tools is limited, especially in rural or low-income areas. Siddarth’s app could level the playing field, making powerful diagnostics as easy as tapping your phone screen.
Imagine a future where your phone becomes your first line of defense against silent killers like cardiac diseases. That future is now within reach... and it started in a teen’s bedroom in Texas.
The Challenges Ahead
Despite its success, Circadian AI still faces hurdles. Regulatory approval, medical certifications, and integration into existing healthcare systems are complex processes. The app is not yet available to the general public, and Siddarth emphasizes it should be used only by trained clinicians... for now.
But the momentum is real. Tech giants and healthcare professionals alike are watching this space, and investment interest is growing.
If Siddarth continues at this pace, the entire medical AI industry could soon be racing to keep up.
Conclusion: One Teen... One App... One Revolution
It ain’t every day a high schooler reshapes the future of medicine. Siddarth’s story is more than inspiring... it’s a wake-up call to what’s possible when young minds are empowered with tools and vision.
Sure, there are hurdles. Sure, the tech needs refining. But if a 14-year-old can build an app that detects heart disease in 7 seconds, what’s stopping the rest of us from dreaming big?
The world need more stories like his. And more kids like Siddarth.
