Young Tech Prodigy Develops App for Early Heart Problem Detection
SIDDARTH NANDYALA – The 14-year-old entrepreneur from Dallas, Texas, has made waves in the medical and tech worlds with his groundbreaking mobile application, Circadian AI. This innovative app can detect heart-related issues in just seconds, offering a faster and more accessible way to diagnose heart conditions early.
Circadian AI uses heart sound recordings captured through a smartphone to analyze and detect potential cardiac issues. With an impressive accuracy rate of 96%, the app has already been tested on over 15,000 patients in the U.S. and 700 in India, proving its reliability and potential to improve early diagnosis.
The app also underwent testing at the Guntur Government General Hospital in Andhra Pradesh, India. There, it showed promising results in real-world settings. Following the trial, Siddarth was invited to meet with Andhra Pradesh Chief Minister N Chandrababu Naidu and Deputy CM Pawan Kalyan, both of whom praised the young innovator’s work. CM Naidu even tweeted his admiration, calling Siddarth an inspiration and promising support for his future endeavors.

Though born and raised in the U.S., Siddarth’s family traces its roots to Andhra Pradesh. His father, Mahesh Nandyala, is also a businessman. Siddarth completed junior high at Lawler Middle School in Frisco, Texas, and is now pursuing a Bachelor of Science in Computer Science at The University of Texas at Dallas—all while still in his teens.
In 2023, Siddarth founded STEM IT, an initiative aimed at reshaping how STEM education is taught by training students to adapt to the fast-evolving world of technology. He has since received numerous accolades, including Innovator of the Year (2023) from the Frisco Chamber of Commerce and the title of National STEM Champion.

Currently, he is developing another app as per PEP.ph focused on creating more affordable prosthetic arm technology, further proving that his passion for innovation and social impact goes beyond the digital space.
