StopSlouching - Your webcam notices when you slouch

I’m the maker of StopSlouching. The product is easiest to explain by trying it: calibrate your seated position, deliberately slouch for a few seconds, and see the alert fire. It uses an on-device pose model, so webcam frames aren’t uploaded. The reminder responds to your posture relative to your calibration rather than a timer. The free web demo needs a computer with a webcam and no account. Chrome and Edge are the best starting point. Pro keeps the reminders running during your workday; one subscription covers the web app, Chrome extension, and Windows desktop app. Monthly is $2.99, yearly is $24.99, and there’s a $39.99 one-time option. Every plan has a 14-day money-back guarantee. What would help you decide whether to keep this running at your desk: a longer demo, more control over reminders, or clearer setup guidance?
