SELFLOOPS HRV – Recovery, Readiness & Performance
SELFLOOPS HRV is a professional-grade app to measure and analyze heart rate variability (HRV)—trusted by pro athletes, coaches, and researchers to track recovery, stress, fatigue, and training readiness.
Using precise beat-to-beat (R-R interval) data from Bluetooth heart rate monitors, SELFLOOPS delivers highly accurate HRV insights used in sports science and performance optimization.

Track your HRV daily to understand when to push harder or recover, reduce the risk of overtraining, and improve performance over time.
