Getting Started
Which AirPods work with SitTall?
SitTall works with AirPods Pro 2nd generation and AirPods 4 ANC. These models include the head motion sensors required for posture tracking. Earlier models and standard AirPods 4 (without ANC) do not have head motion capability.
What Mac do I need?
SitTall requires macOS 14 Sonoma or later. It runs natively on both Apple Silicon and Intel Macs. There are no other hardware requirements beyond supported AirPods.
How do I calibrate SitTall?
Click the SitTall icon in the menu bar and start monitoring. 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. You only need to do this once — calibration is saved between sessions.
Does SitTall start automatically?
Yes. If you enable "Start at Login" in Settings, SitTall will launch automatically when you log in and begin monitoring as soon as your AirPods connect.
Troubleshooting
SitTall says my AirPods are unavailable. What do I do?
Make sure your AirPods are connected to your Mac via Bluetooth, not your iPhone or iPad. Open System Settings → Bluetooth and confirm they appear as "Connected." If they're connected to another device, you may need to manually switch them by holding the AirPods case button near your Mac.
The posture detection feels inaccurate. How do I fix it?
Try recalibrating. Click the SitTall 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 can detect drift. You can also reduce the sensitivity threshold in Settings.
I'm not receiving notifications. Why?
Check that SitTall has notification permission: open System Settings → Notifications → SitTall and ensure notifications are enabled. Also check that you haven't accidentally set a very long alert duration in Settings (default is 5 minutes of bad posture before alerting).
SitTall alerts me too often / not enough.
Open Settings from the SitTall 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.
How do I recalibrate SitTall?
Click the SitTall icon in the menu bar and select Recalibrate. This clears your current calibration and starts the two-step capture process fresh. Your settings are not affected.
Privacy & Data
Does SitTall collect any data about me?
No. SitTall collects zero data. Your motion data is processed entirely in memory on your Mac and is never written to disk or transmitted anywhere. See our full Privacy Policy.
Does SitTall use my camera?
No. SitTall never accesses your camera. Posture detection uses only the head motion sensors in your AirPods.
Does SitTall require an internet connection?
No. SitTall works entirely offline. It makes no network requests and has no cloud component. It runs in the macOS App Sandbox and cannot access the internet.
