When I first heard that a 14-year-old had created an app that could detect heart disease almost instantly, I honestly thought it was a stretch. I mean, heart disease? That’s the kind of thing we usually leave to cardiologists with decades of training and equipment worth thousands of dollars.
But after digging into the story of Siddarth Nandyala and his app Circadian AI, I’ve changed my mind. This isn’t a gimmick. It’s actually a glimpse into how AI and raw curiosity can completely reshape the future of medicine, especially for people who don’t have access to expensive tests or specialists.
The Global Heart Problem No One Talks About Enough
Let’s set the stage: Heart disease is the #1 cause of death worldwide. Every year, millions of people suffer heart attacks or strokes without ever being diagnosed with anything beforehand.
Why? Because detecting cardiovascular issues usually requires expensive imaging, invasive procedures, or access to specialists that many people, especially in lower-income communities, simply don’t have.
A lot of people only find out they have heart problems when it’s already too late. And that’s the exact problem Siddarth wanted to solve.
How Does the App Work? (It’s Smarter Than It Sounds)
Circadian AI uses something almost everyone already has, a smartphone microphone.
You literally just hold your phone close to your chest while the app records your heartbeat. The sound is cleaned up using noise-cancellation tech, and then analyzed in the cloud using a machine learning algorithm trained to detect subtle abnormalities.
And when I say subtle, I mean patterns that would normally require an electrocardiogram (ECG) or a trained cardiologist to identify. We’re talking arrhythmias, heart valve issues, early signs of coronary artery disease, and even congestive heart failure.
In a matter of seconds, the app gives users a visual summary of their heart sound, flags potential issues, and recommends whether they should seek professional follow-up.
This isn't some random experiment either, it’s been tested on a huge scale.
Real Clinical Trials. Real Accuracy.
Circadian AI has already gone through clinical trials in the U.S. with over 15,000 people and another 3,500 in India. And the results? Over 96% accuracy when compared to traditional diagnostic tools like ECGs.
Let me just pause here. That kind of performance is staggering for a phone app. It won’t replace your doctor (and it’s not meant to), but as a screening tool, it’s brilliant, especially for catching early signs of disease in places where early detection is often impossible.
Right now, the app is only being used by trained professionals as it goes through more regulatory reviews and clinical validation, which makes sense. But even in its current form, it’s already saved lives.
What’s Next? Even Bigger Goals
Siddarth isn’t stopping at hearts. He’s now exploring whether the same sound-based analysis could help detect lung diseases, things like pneumonia or pulmonary embolism, just by analyzing breathing patterns.
Honestly, I wouldn’t bet against him. He’s part of a new generation of thinkers using AI not just to automate tasks, but to solve real, urgent problems.
So, Why Does This Matter?
Because this story isn’t just about a teen genius or cool technology.
It’s about what happens when tech, medicine, and access intersect. In rural areas, underserved populations, or low-income countries, early detection of chronic disease is rare. By the time someone gets a diagnosis, they’re often already in a critical state.
But what if a tool like this could be rolled out globally? What if one app on your phone could give you enough insight to take action before things get dangerous?
That’s why this matters.
Final Thought: The Human Side of AI in Medicine
It’s easy to feel skeptical about AI in healthcare, especially when we see headlines about robots replacing doctors or algorithms making decisions. But stories like Siddarth’s remind us of the potential for compassionate innovation.
At the end of the day, this app isn’t about data or code. It’s about helping people, people who might otherwise slip through the cracks of the healthcare system.
And to think it all started with a teenager who wanted to make a difference.
