Vital Sentinel: Nervous System

Catch rising stress early before it pulls you out of focus or starts running your body in the background.

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.

Sleep Mood Signals (overnight)
A single, glanceable state—calm, heightened, regulated, or a specific signal (fear, tension, panic) so you can orient without analysis.

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.
