Name: SighSense – Stress Reset & Vagal Score
Author: LiveLongerNow.org

Feel tension building while you sit still? SighSense notices it and guides you through a short breathing reset you can follow with your eyes closed.

Stress at your desk, in traffic or in a meeting looks different from exercise: your heart rate rises while your body stays still. SighSense watches for exactly that pattern and offers a physiological sigh - two inhales through the nose, one long exhale through the mouth - guided by distinct vibration rhythms.

WHAT YOU GET

* Quick Reset: 3, 5 or 8 cycles of the physiological sigh (about 30-90 seconds)
* Deep Reset: 5 minutes of cyclic sighing, the practice studied at Stanford (Balban et al., Cell Reports Medicine, 2023)
* Haptic guidance: inhale, top-up and exhale each feel different. Blind Mode switches the screen off for meetings
* Breathing pace: Standard (9-second cycle) or Calm (12-second cycle)
* Still-Stress Nudge: an optional prompt when your heart rate stays elevated while you are inactive. Quiet hours, meeting mode and a daily limit keep it polite, and your feedback tunes its sensitivity
* Vagal Score 0-100: daily recovery readiness from a 2-minute Morning Check (HRV), resting heart rate and stress trends
* Heart-rate change after every reset
* Weekly view and a glance for your widget loop
* Optional: save sessions to Garmin Connect
* Works with buttons and touch
* 100% free. No account. Your data never leaves your watch.

GETTING STARTED
For the first 7 days SighSense learns your baseline: do the Morning Check after waking and you will see "Calibration 3/7" until your Vagal Score is ready. Nudges stay silent for the first 3 days.

GOOD TO KNOW

* Morning Check HRV needs a watch that provides beat-to-beat intervals; otherwise the score is estimated from resting heart rate (marked as approximately).
* Garmin Stress and Body Battery are used on watches with Connect IQ 3.3+.
* The glance is available on watches with Connect IQ 4.0+.
* "Open on phone" needs the Garmin Connect app on a paired phone.
