A fixed pace is useful—but it is still a preset
Many breathing apps begin around six breaths per minute. That can be a practical slow-breathing starting point, but it does not show how your own beat-to-beat pattern responded.
Personal resonance can differ across people. RHz explores several rates so your starting pace is informed by measured feedback rather than a universal assumption.
What a guided sweep adds
Your external monitor sends the timing between heartbeats. RHz guides your inhale and exhale, groups the response by breathing rate, and returns the pace with the strongest measured response in that session.
- Full Sweep explores a broader coarse range and then a finer range.
- Quick Tune checks a shorter fixed range.
- Adaptive practice can adjust during the session and use past sessions as a starting point.
A practice reference, not a diagnosis
The pace RHz identifies is a practical wellness and training reference. It is not a permanent medical measurement, and the app is not intended to diagnose, monitor, treat, cure, or prevent a medical condition.
