Push notification tell you when to take a break from the computer or phone at the best moment based on heart rate. Vital Sentinel is a quiet, watch-first companion for therapy, meditation, and demanding workdays. It pays attention to subtle changes in your physiology like heart-rate patterns and surfaces gentle awareness in moments you’re least likely to notice on your own. No journaling. No tagging. No homework. Just real-time awareness, right on your wrist. BUILT FOR REAL LIFE Stress isn’t always psychological. Your nervous system responds to sleep, caffeine, illness, sustained effort, emotions, and even excitement. Vital Sentinel is designed to stay grounded and non-alarming by recognizing context movement, cooldown, and recovery so you get fewer false alarms and more useful signals. When patterns are consistent, it can offer quiet support for signals that resemble: • fear-like spikes (startle or anxiety patterns) • panic or acute anxiety (high-intensity activation) • mild tension or nervousness (a subtle sympathetic edge) WHAT YOU GET Nervous System Strain (adaptive 6-hour trend) A simple 0–100 signal reflecting how strained your system has been based on recent heart-rate data. It rises with sustained activation or sharp spikes while still, and adapts to your patterns over time rather than fixed thresholds. When you return to baseline, you’ll see Back in Balance a small cue that helps you notice recovery. Stand-up break notifications When your heart rate changes or stays elevated during stillness, Vital Sentinel can gently suggest a stand-up reset so you can interrupt strain before it builds. Sleep Mood Signals (overnight) A single, glanceable state—calm, heightened, regulated, or a specific signal (fear, tension, panic) so you can orient without analysis. Export to CSV Explore sleep or daytime patterns through conversation with AI. Soft haptic check-ins Subtle taps when your body shows sharp rises or sustained strain, especially during stillness. Optional prompts are available for fear-like patterns, tension, and panic-like activation. Sensitivity and quiet hours are fully adjustable. 1-minute grounding reset A brief, watch-guided reset you can use between meetings, before difficult conversations, after commuting, or when you feel activation building. Also useful during sudden fear or panic-like spikes. Agitation detection When physiology suggests anger-like activation (distinct from fear or panic), Vital Sentinel can offer a calming prompt to help prevent escalation. Positive reinforcement after intensity Gentle acknowledgment when your system settles so regulation becomes something you notice and trust. Optional: Voice Stress Radar (on-device) If enabled, Vital Sentinel can look for stress-related language (for example, “overwhelmed” or “I can’t do this”) using on-device speech processing. No recordings are stored. Only trends are kept for personal awareness. Overnight insight Low-key sleep trends such as breathing and wrist temperature to support recovery without scoring or judgment. WELL-SUITED FOR • Therapy and nervous-system regulation (somatic work, EMDR, IFS, breath work, meditation) • High-pressure roles (founders, clinicians, educators, emergency services, leaders, caregivers) • Anyone who wants body-first awareness without tracking their entire life • People who want quiet support during sudden fear, tension, or panic-like moments PRIVACY, BY DESIGN No account required. No selling or sharing. Data stays on your device in Apple Health. 7-day free trial $3.99 / month · $29.99 / year Begin with awareness. Let calm follow. Vital Sentinel is a wellness companion, not a medical device. It is not intended to diagnose, treat, cure, or prevent any medical condition.
