What's New in Sympathetic
1.5.6
October 29, 2026
The live heart-rate-by-breath line is smoother and no longer breaks at the start of a slow exhale. Saved recordings are re-analysed with the same beat filter. After a session, a progress bar shows the ECG check, and a compact indicator shows while the session saves. Breathing cues resume automatically when you return to the app, and the resonance estimate card links to its plots. Expanding the ECG strip on Breathe no longer shows a blank screen. pNN50, RSA power, coherence and the R–R interval display have been removed to simplify the summaries; older records still open.
