Siddharth Nandyala, a 14-year-old from Dallas, has created Circadian AI, an app that detects heart disease within 7 seconds by analysing heart soundsthrough a smartphone. The world`s youngest AI-certified professional, Nandyala has developed this app using advanced algorithms, achieving a 96% accuracy rate after testing on over 15,000 patients in the US and 700 in India.

The app was tested at the Government General Hospital in Guntur, India, and has been praised for its potential to improve healthcare access in underserved communities. Nandyala, a student at the University of Texas at Dallas, aims to make rapid heart disease diagnoses more accessible and lifesaving.
