How it works
For resting HRV measurements (the kind that matter most for recovery tracking), iPhone PPG accuracy is within 3–5ms RMSSD of the Polar H10. The gap is minimal at rest.
For HRV during exercise or real-time cardiac monitoring, the H10 is more reliable. iPhone camera requires you to sit still — it's a wellness logging tool, not a live workout sensor.
The best HRV tool is the one you actually use every morning. Pulse Rate takes 2 minutes with no extra gear — far more likely to become a consistent daily habit.
Download Pulse Rate and commit to 30 morning readings. The trend data you build in a month is worth more than any single high-precision spot measurement.
