Your day, minute by minute.
Your health, over time.
01Understand what drives your body's reactivity
Your Reactivity Monitor™ gives you a live timeline of how your body responds to daily demands. Zoom into any peak to see what drove it and how your body came back to baseline. If you stay reactive for a prolonged period, your watch vibrates gently to invite you to log how you feel.
02Dive into the details
Open any day to find your full picture across sleep, stress, activity, and cycle. See your key metrics at a glance in the Home tab, or go deeper into any pillar for the detail.
03Spot shifts in your patterns
Your Cumulative Stress trend shows whether the pressure on your body is holding steady or building up, and how sleep, stress and activity interact over weeks. When something shifts, Insights flag it and suggest what to do, so you can act before pressure turns into load.
04Practice in the moment (iOS only)
Guided breathing, and CBT exercises are available any time you need. Whether your watch nudged you or you came on your own, Intentions gives you the tools to support your health.

Everything Polsen tracks,
explained.
Prolonged stress vibration
When your body has been more reactive for an extended period, your watch vibrates gently — a quiet nudge to pause, identify what's driving it, and reset with built-in Check-ins and breathing exercises.
Daily stress states
Based on how long your body stayed under physiological stress, how often it spiked, and how quickly it recovered, Polsen watches give you a daily read of how you're handling daily demands — from High Resilience to High Load or Delayed Recovery.
Cumulative Stress duration
Your Overview tracks how much time your body has spent under stress in the recent days: you can see whether pressure on your body is building, and catch early signs of wear and tear before it affects your health.
Cumulative Stress recovery & frequency
Your Cumulative Stress duration is influenced by your stress recovery and frequency: how quickly your body returns to baseline after each spike, and how often it activates throughout the day. If small things are triggering your body too often, CBT sessions help you handle daily demands better. If you're struggling to come back down, prolonged reactivity vibrations nudge you to reset.
