Posture Reminder AI

What It Does

Posture Reminder AI is a Mac application that uses on-device computer vision to monitor your posture in real time and send timely alerts when you slouch. Built by Leon Wei, a former Apple machine learning engineer, the app runs entirely on your Mac—keeping all posture data private and local.

Who It's For

Designed for Mac users who spend long hours at a desk, Posture Reminder AI helps developers, knowledge workers, and remote employees combat chronic neck pain, back discomfort, and poor posture habits. Whether you work on a MacBook, use an external monitor, or switch between sitting and standing desks, the app adapts to your setup.

Key Features & Capabilities

• Personalized posture model: Quick two-step setup captures your natural upright posture and typical slouch, tuning alerts to your body and desk configuration
• On-device Edge AI: All computer vision processing happens locally using Apple's machine learning frameworks—no cloud uploads, no recordings, no data resale
• Real-time alerts: Notifications fire as soon as posture drift is detected, helping you correct your position before discomfort sets in
• Depth-aware analysis: Advanced computer vision distinguishes subtle postural changes
• Flexible camera support: Works with built-in Mac cameras, external webcams, or iPhone via Continuity Camera
• Customizable reminder frequency: Adjust alert intervals as your posture habits improve
• Launch at login: Runs automatically in the background when you start your Mac

Typical Workflows & Use Cases

After a one-minute setup, Posture Reminder AI runs silently in the menu bar. When it detects the slouch pattern you trained it to recognize, a notification prompts you to sit up straight. Users report improved posture awareness even away from the computer after consistent use. The app integrates seamlessly with macOS Focus modes and supports Family Sharing for up to five people on the annual plan.

What Differentiates It

Unlike physical posture correctors or generic reminders, Posture Reminder AI learns your specific posture drift and desk setup. Privacy is built in: no video leaves your device, and the app never stores images. Trusted by Mac users worldwide since 2021, it supports both Intel and Apple Silicon Macs running macOS Tahoe or newer.
