About this app

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

Ratings and reviews

had high hopes, unfortunately getting constant inaccuracies. Using Garmin Pro Plus-- Simple connection, the UI is straightforward and detailed, easy to interpret, but the app keeps showing high artifact even when sitting very still, and HR is far off-- 75-90 when its 56-57 shown by wearing a separate monitor simultaneously. Incredibly disappointing, and brings all the other data readings into question. what's up guys? This could be a great app

I connected one Rhythm24 band with the app, and although one band connected and HR and HRV RR intervals data was displayed, other Rhythm24 bands that I connect to the same app was not displaying any HRV data, just the HR data. If you can help me understand why that's the case, perhaps I can rate the app higher because it's not a bad app after all.

Worked immediately with my Bryton HRM with both BLE and ANT+ that nothing else seems to like. Unlimited recording. No paid version and no ads. Didn't know apps like this still existed. Excellent work.
