ONDA Life — Live Coherence & HRV Biofeedback See your body respond live — as you breathe, not after. Most breathing and meditation apps hand you a score when the session ends. But biofeedback is a loop: you can't tune what you can't see while you're doing it. ONDA shows your body responding in real time, during the practice. START WITH JUST YOUR IPHONE Rest a fingertip on the rear camera and watch your pulse respond live as you breathe — no extra hardware, no account. It's real photoplethysmography (the same principle as a pulse oximeter), processed entirely on-device. GO DEEPER WITH APPLE WATCH Connect an Apple Watch and ONDA renders a live coherence waveform from your heart-rhythm data — the breath-by-breath synchronization of heart and breathing that a camera can't capture. Plus haptic guidance through every session. WHAT YOU GET — Live pulse feedback from your iPhone camera — Live coherence waveform with Apple Watch — 3-minute protocols: resonance-frequency breathing, extended exhalation, slow paced breath, and interoceptive awareness — A resting-HRV trend (real SDNN) that tracks your baseline over weeks — Three core practices free, forever — no sign-in — Real-time stress and energy estimates from your heart-rate and HRV trends THE SCIENCE, NOT JUST THE VIBE Every protocol comes with its physiology — the mechanism, the pathway, why it shifts you toward parasympathetic. Built for people who want to understand what their breath is actually doing to their nervous system. We name what's measured and don't dress up what isn't. STRUCTURED PROGRESSION Your training is organized into 8 progressive levels — from basic interoceptive awareness to advanced nervous-system protocols, each one deepening how you read and work with your own data. BUILT FOR — Biohackers tracking HRV and vagal tone — Anyone working through stress, anxiety, or burnout — Breathwork practitioners (resonance, Oxygen Advantage, polyvagal) who want quantified feedback — Apple Watch users whose data should drive practice, not just sit in HealthKit REQUIREMENTS — iOS 15+ — iPhone camera for fingertip pulse (optional, on-device) — Apple Watch for live coherence (optional — unlocks the deeper layer) — HealthKit access for heart rate and HRV PRIVACY Your HealthKit data stays in HealthKit. The camera pulse signal is processed on-device — never written to disk, saved to Apple Health, or sent off your device. ONDA reads heart rate and HRV for real-time analysis only — nothing is sold or shared with third parties. SUBSCRIPTION Three core practices free forever, no account.
