SELFLOOPS HRV

SELFLOOPS HRV helps you measure, analyze, and understand your heart rate variability (HRV) with high accuracy.

Used by professional athletes and Olympians, SELFLOOPS HRV gives you reliable insights into your recovery, training readiness, and overall performance—so you can train smarter every day.

Why HRV matters

Heart rate variability (HRV) reflects how your body responds to training, stress, and recovery. By tracking your HRV, you can better understand when to push harder and when to rest.

Key features
•Accurate HRV measurement from beat-to-beat (R-R) intervals
•Advanced metrics: RMSSD, ln(RMSSD), SDNN, pNN50, AVNN
•Daily trends and long-term analysis to monitor progress
•Clear insights into recovery and readiness
•Export your data (CSV) and share it via email, Google Drive, Dropbox, and more
•Upload and analyze your data on selfloops.com

Compatible devices

Works with most Bluetooth heart rate monitors.
For best accuracy, use a chest strap that supports R-R interval data (e.g., devices from Garmin, Polar, Wahoo).

Important notes
•Some heart rate monitors do not provide the R-R data required for HRV analysis
•Make sure your sensor is not connected to another app or device during use
