Features

Everything you need.
Nothing you don't.

A posture corrector that respects your workflow - invisible when you're upright, present when it matters.

Real-time Detection

Continuously tracks forward head drift, side tilt, and gradual posture collapse using your AirPods' 6-axis motion sensors - 60 times per second.

One-tap Calibration

Sit up straight, then slouch. SitTall - Fix Your Posture learns your personal good and bad posture baseline in two taps - no measurements, no complicated setup.

Smart Reminders

Alerts fire only when bad posture persists - never for a momentary glance. Snooze with one click when you need to stay in the zone.

Fully Private

All motion analysis runs locally on your Mac. No camera used, no account required, no data ever leaves your device. Not even to us.

Menu Bar Native

Lives quietly in your Mac menu bar. No Dock icon clutter. One click to check your posture state, adjust settings, or pause monitoring.

Fully Customizable

Tune sensitivity, alert duration, and cooldown to fit your work style. Go strict for focused sessions, or gentle for casual days.

How it works

Up and running
in under a minute.

SitTall - Fix Your Posture is designed to get out of the way. Calibrate once, then forget about it - until you slouch.

  1. Calibrate once

    Sit up in your best posture and tap "Capture good posture." Then slouch naturally and tap "Capture bad posture." SitTall - Fix Your Posture now knows your personal range.

  2. Wear your AirPods

    Work normally. SitTall - Fix Your Posture watches silently from the menu bar, tracking forward drift, side tilt, and gradual collapse with the sensors already in your ears.

  3. Sit up when reminded

    After a configurable period of bad posture, you'll get a gentle nudge. Dismiss, snooze, or just sit up - posture corrected, back to work.

Privacy

Your data never
leaves your Mac.

Built with privacy as a first principle. No account. No posture servers. No in-app analytics. Just a posture app that works quietly and disappears.

No account required

Download and use immediately. No email, no sign-up, no subscription ever.

No camera, ever

Detection uses only AirPods motion sensors. Your camera is never accessed or requested.

No cloud, no sync

All processing happens on-device. Nothing is transmitted, stored externally, or shared.

App Sandbox

Runs in macOS App Sandbox with minimal permissions. Cannot access your files or network.
