What feels strongest right now? Is your heart racing? Is your chest tight? Are your thoughts looping? REZET is a physiological toolkit, not a meditation app. It acts as an emergency brake for an overactive autonomic nervous system. When you experience acute stress, panic, or overwhelm, your biology is stuck in a sympathetic (fight-or-flight) or dorsal vagal (freeze) response. REZET provides you with the exact, science-backed respiratory protocols needed to mechanically stimulate your vagus nerve and force a physiological state shift back to baseline. No spiritual fluff. Just clinical mechanics. Select your current somatic state, and follow the visual and haptic pacing. NEW: MEASURE VITALS Use the rear camera and flash for a dedicated 1-minute fingertip reading. A live camera preview helps you place your finger correctly, the measurement starts automatically once pulse lock is stable, and REZET processes the full capture window to estimate: β€’ HRV β€’ Heart rate β€’ Breathing rate Breathing rate is inferred from cyclical heart rate changes during the measurement. Vitals are provided for wellness trends and self-awareness only, not diagnosis or medical monitoring. NEW: CUSTOM BREATHING PROTOCOLS Create and save your own breathing protocols with custom inhale, exhale, and optional hold timings. You can choose whether a session ends by total time or by completed rounds, then restart saved custom protocols in one tap from Home. THE PROTOCOLS: We map your acute symptoms to precise respiratory ratios designed to counteract them via heart rate variability (HRV) and vagal tone manipulation. β€’ Tachycardia (Heart Racing): 4-7-8 pacing directly stimulates the vagus nerve, utilizing breath retention to trigger a rapid parasympathetic response and lower heart rate. β€’ Chest Tension: 4-4-4-4 (Box Breathing) anchors the autonomic nervous system through equal respiratory distribution, preventing hyperventilation and releasing physical constraint. β€’ Racing Thoughts: Micro-varied interval pacing demands active cognitive tracking, disrupting Default Mode Network (DMN) loops. β€’ Sensory Overwhelm: Extended exhalations mechanically decrease heart rate via respiratory sinus arrhythmia (RSA), signaling biological safety to the brainstem. β€’ Dorsal Shutdown (Numbness): 6.0/6.0 coherent pacing gently up-regulates the system without triggering an adrenaline spike. β€’ Restlessness: 5.5s Resonant Frequency synchronization maximizes HRV, bringing the cardiovascular and respiratory systems into perfect alignment to clear cognitive fog. SYSTEM FEATURES: β€’ Zero Friction: No long intro videos, no mandatory sign-ups. Immediate access to physiological regulation in two taps. β€’ Measure Vitals: A guided 1-minute camera reading for HRV, heart rate, and breathing rate estimates using the rear camera and flash. β€’ Custom Protocols: Create, save, and restart your own breathing sessions with custom timings and time-based or round-based targets. β€’ Clinical Insights: Detailed neurological and biological mechanics explaining why each protocol is effective. β€’ Haptic & Visual Pacing: A high-contrast adaptive interface combined with precise haptic feedbackβ€”allowing for screen-free, eyes-closed regulation. β€’ Adaptive Intensity Checkpoints: If a respiratory ratio exceeds your current CO2 tolerance, the algorithm safely down-scales the timing mid-session. β€’ Dose-Dependent Sessions: Choose 1, 3, or 5-minute intervals based on your immediate physiological requirement. Stop trying to think your way out of a biological response. Use your physiology to change your psychology. Download REZET to gain mechanical control of your nervous system.

Verdict

The call

The clearest difference is ads: innself at none against REZET's shown. innself also leads on iOS requirement (13.0 vs 15.1). REZET's advantage is update cadence (every 6 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.
