How it works
Take your HRV reading within 5 minutes of waking, before coffee or movement. Consistency of timing is the most important factor for reliable HRV trends.
HRV requires a longer sample than basic heart rate. Keep your fingertip steady on the camera for at least 2 minutes to capture enough beat-to-beat intervals for analysis.
Individual HRV readings fluctuate widely due to normal daily variation. Pulse Rate shows your rolling 7-day average — this trend line is far more meaningful than any single data point.
Log notes on sleep quality, training load, and stress alongside your HRV. Over weeks, you'll see clear patterns in what raises or suppresses your recovery baseline.
