Hey Product Hunt! I'm Adam.

I spend most of my day at a MacBook, and by evening my back lets me know. I tried a few posture apps, but they all felt bolted on: desktop notifications I learned to ignore, extra windows to minimize, nagging I eventually switched off.

So I built Spino. It lives in the menu bar, watches your posture through the webcam and dims the screen when you slouch. Sit up and it clears. No pop-ups, no dashboards, just a nudge you can't really ignore.

A bit of background: at my day job (RealEye) we build webcam-based eye tracking, so on-device computer vision is home turf for me. Everything runs locally, nothing leaves your Mac.

Pricing: free for 4 hours of monitoring a day. If you want it all day, a lifetime license is 5€ / $6. No subscription.

This isn't my first biohacking side project (RIP my WakeTheFckUp alarm clock), so I'd love honest feedback:

After an hour of use, does the dimming feel helpful or annoying?
Does detection work well with your camera and desk setup?
What would make you keep it running every day?

Thanks for checking it out!
