Dorso

A macOS app that blurs your screen when you slouch.

Dorso monitors your posture in real-time using either your Mac's camera or AirPods motion sensors. When it detects that you're slouching, it progressively blurs your screen to remind you to sit up straight. Maintain good posture, and the blur clears instantly.

Permissions

Camera Mode: Requires camera access. When you first launch the app, macOS will ask for permission.

AirPods Mode: Requires Motion & Fitness Activity permission (macOS 14+). This allows the app to read head motion data from your AirPods.

If you accidentally denied permission, you can grant it later in System Settings > Privacy & Security > Camera or Motion & Fitness Activity.

Usage

Once launched, Dorso appears in your menu bar with a person icon. The app continuously monitors your posture and applies screen blur when slouching is detected.

Menu Bar Controls

Click the menu bar icon to access:

• Status - Shows current state (Monitoring, Slouching, Good Posture, etc.)
• Enabled - Toggle posture monitoring on/off
• Recalibrate - Reset your baseline posture (sit up straight, then click)
