If you spend 8+ hours at a Windows PC, your posture is probably paying the price. You know you should sit up straight. The problem is you forget about it the moment you start focusing on work.
A posture app for Windows can solve that by using your webcam and AI to watch your posture in the background and alert you when you slouch.
