Heart Rate Fragmentation

👋 Hey Product Hunt! I’m Austin, a medical researcher and the maker of this heart rate fragmentation app. I built this after seeing how often traditional heart rate metrics miss subtle — but important — signs of stress, poor recovery, or early health issues. Heart rate fragmentation is a novel, new, research-backed way to assess how well your autonomic nervous system, you’re ‘rest and digest’ and ‘fight or flight’ systems, is functioning — and now, with this app, anyone with a wearable can start tracking it. The first to use ECG to evaluate this on a wearable technology. This launch is just the beginning. I’d love your feedback on the UX, feature ideas, or how it could better support your health goals. Thanks so much for checking it out — and feel free to AMA! 🙌
