Nervous System Nudge Closed test

Your body knows you're wound up before you do. Now your watch does too.

Nervous System Nudge sits quietly on your Apple Watch or Garmin, spots when your nervous system is revving up while you're sat still, and gives you one gentle buzz. No lectures. No streaks. Just a nudge to notice.

How it works

Three steps. No homework.

  1. 1 It notices

    Heart rate, checked against your own calm (on Garmin, heart rate variability and stress too). Racing heart while you're on the sofa? That's the bit it watches for.

  2. 2 One gentle buzz

    Your watch asks What's going on? One press to answer: wound up, fine, not sure, exercise, excited. Or ignore it. It won't sulk.

  3. 3 It learns your pattern

    Every answer teaches it what wound up looks like for you, not for an average person. Say fine a lot and it backs off.

Watch and phone

Small things, one button away.

  • Check in whenever

    Don't wait to be asked. Tell it how you're doing any time, and it learns from that too.

  • Quick log

    Water, coffee, meds taken, food and more, one tap each. So it can tell a double espresso from a wobble.

  • Breathe for 60 seconds

    In for four, out for six, counted on the watch. A minute to slow things down.

Your data

Your heartbeat is nobody's business model.

  • It's yours
