How does SitTall - Fix Your Posture work?

How do I calibrate SitTall - Fix Your Posture?

You'll be prompted to sit up straight and tap "Capture good posture," then slouch naturally and tap "Capture bad posture." The whole process takes about 10 seconds.

Does SitTall - Fix Your Posture start automatically?

SitTall - Fix Your Posture says my AirPods are unavailable. What do I do?

The posture detection feels inaccurate. How do I fix it?

Try recalibrating. Click the SitTall - Fix Your Posture menu bar icon → Recalibrate. When capturing your good posture, sit in your most upright, comfortable position. When capturing bad posture, show your most common slouch. The bigger the difference between the two positions, the more reliably SitTall - Fix Your Posture can detect drift. You can also reduce the sensitivity threshold in Settings.

I'm not receiving notifications. Why?

Check that SitTall - Fix Your Posture has notification permission: open System Settings → Notifications → SitTall - Fix Your Posture and ensure notifications are enabled.

SitTall - Fix Your Posture alerts me too often / not enough.

Open Settings from the SitTall - Fix Your Posture menu bar icon. Increase the Alert Duration to wait longer before triggering a notification, or increase the Cooldown to prevent back-to-back alerts. Adjusting the Sensitivity threshold changes how far from your good posture baseline triggers a warning.
