If you spend 8+ hours at a Windows PC, your posture is probably paying the price. You know you should sit up straight. You just forget the moment you start focusing on work.
A posture app for Windows uses your webcam and on-device AI to watch your posture in the background and nudge you when you start to slouch.

Windows-Specific Details
Webcam compatibility: SitApp works with any webcam Windows recognises - built-in laptop cameras, USB webcams, external cameras. If Windows sees it, SitApp can use it.
System tray: SitApp sits in your system tray (bottom-right corner) so it’s always accessible without cluttering your taskbar.
Startup: You can set SitApp to launch at login, so monitoring starts the moment your workday does.
Resource usage: AI inference runs on-device. Most users see less than 5% CPU usage during active monitoring. It’s quiet.
