How to create a revolutionary training app, and what does every software developer need to remember

Our guest, Marco Altini, started HRV4training in 2012 - a mobile platform designed to measure heart rate variability (HRV) and quantify stress in order to improve athletic performance, training loads, and recovery. Trusted by over 200,000 users, including Olympic medalists and professional teams, HRV4training stands out as the first and only app that can reliably measure HRV using just a smartphone's camera. This innovative technology allows athletes and coaches to monitor their physiological responses and make data-driven decisions to optimize their training and recovery. Marco's deep expertise in biometrics, physiology, and data analytics has enabled him to create a highly accurate and accessible tool for performance optimization. The widespread adoption of HRV4training across elite sports demonstrates Marco's ability to transform cutting-edge research into practical, user-friendly solutions that are revolutionizing the way athletes approach their training and well-being.
