Store description excerpt
Vagal Sense organizes and documents heart rate variability (HRV) in professional health practice. WHO IT IS FOR Physiotherapists, osteopaths, physicians, psychologists and exercise professionals who already use HRV in practice — or who want to start doing it rigorously, without an improvised spreadsheet. If you already measure resting heart rate and write it in a notebook, Vagal Sense is the next step: the same gesture, with a record that accumulates and a comparison that holds up. WHAT VAGAL SENSE ORGANIZES • Response patterns (phenotypes F1–F8) — the pattern observed in that session, with context, instead of a number on its own. It changes from session to session: an informative trend, not a fixed label for the person. • Structured record across 8 domains — consistent notes per person, session after session. • History per person — how things evolve over time, on your phone. • Mobile-first — built for the flow of a session, not for a desktop in the office. WHAT A SESSION LOOKS LIKE You connect the strap, record a few minutes at rest and follow the tachogram — the beat-to-beat curve — in real time. If you want, you run guided breathing right there, with visual, audio and haptic support, and watch the response happen on the curve itself. At the end, the app computes RMSSD and SDNN, saves the summary with your note, and suggests practices grouped into three tracks: Restoration, Rhythm and Expansion. Next time, today's session sits side by side with the one from three weeks ago. HRV, THE VAGUS NERVE AND BIOFEEDBACK IN PRACTICE The vagus nerve is the main pathway of the parasympathetic branch of the autonomic nervous system, and the variation between heartbeats is the most accessible window onto it. That oscillation follows your breathing — inhaling speeds the heart up, exhaling slows it down — and is known as respiratory sinus arrhythmia, one of the most studied ways to observe vagal tone. That is why RMSSD and SDNN show up in exercise physiology, in rehabilitation, and in research on stress and recovery. Vagal Sense does not replace your reasoning: it records what you observed, in a form that lets you compare today's session with the one from three weeks ago. Guided breathing and real-time biofeedback are available for use during a session. NO HARDWARE REQUIRED Vagal Sense works without a sensor. When you want chest-strap accuracy, the app uses the Polar H10 — the same real RR intervals as Vagal HRV. Watches and rings estimate heart rate with light (PPG): they measure the average well and the exact interval between beats poorly. Since HRV is made of precisely those intervals, a chest strap is what sustains a record you can compare over time. YOUR DATA STAYS ON YOUR DEVICE No account, no server, no cloud. The records of the people you work with never leave your phone — on the Play Store, our Data Safety section declares "no data collected". You export PDF reports whenever you need them, and you can create a full backup as an AES-25
