Sit a little taller

You settle in. Get absorbed.A document, a deadline, a thought worth following. How you’re sitting slips out of mind.

Your focus holds. Your posture slips.Plumb waits to see whether the slouch lasts before reminding you.

A small cue. An easy reset.A soft glow rises at the edge of your screen. Choose your reminder style, with sound or without.

Sit taller. Keep going.The glow fades as you return upright. No reminder to dismiss. No need to leave your work.

A personal starting point

It starts with how you sit.

Show Plumb your upright, slouching, and looking-down positions. It learns the differences, so reminders start with your own baseline.

  1. Sit comfortably upright.

    Give Plumb a starting point for your usual desk setup.

  2. Show it your slouch.

    Then look down, so Plumb can learn how each position differs.

  3. Get back to your day.

    Start a session. Plumb looks for lasting changes while you work.

Your camera helps. Your pictures stay private.Posture detection happens entirely on your Mac.
