Posturr

A macOS app that blurs your screen when you slouch.

Posturr uses your Mac's camera and Apple's Vision framework to monitor your posture in real-time. 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.

Features:

• Real-time posture detection - Uses Apple's Vision framework for body pose and face tracking
• Progressive screen blur - Gentle visual reminder that intensifies with worse posture
• Menu bar controls - Easy access to settings, calibration, and status from the menu bar
• Multi-display support - Works across all connected monitors
• Privacy-focused - All processing happens locally on your Mac
• Lightweight - Runs as a background app with minimal resource usage
• No account required - No signup, no cloud, no tracking
