What is it?

Dorso is a macOS menu bar app that watches your posture in real time. It can use the Mac's camera with Apple's Vision framework to track head and body position, or read head tilt from compatible AirPods (Pro, Max, or 3rd generation and later) without any camera access.

When slouching is detected, the screen blurs progressively, becoming stronger as posture worsens, and clears immediately once you sit up straight. You calibrate a baseline posture first, then adjust sensitivity and a dead zone to control how quickly the blur appears.

Processing happens locally on the Mac, and the app needs no account. It supports multiple displays and can optionally appear in the Dock and Cmd+Tab switcher.
