Glance Switch: Focus follows your eyes: look at a screen, window, or pane

Hey Product Hunt 👋 I work on 2–3 monitors, and I kept typing into the wrong window because focus stayed on the screen I'd just left. Clicking before every switch got old, so I built Glance Switch. It uses the Mac's camera and Apple's Vision framework to work out which screen you're facing, then gives focus to the last window you used there. It does this without a synthetic click, so split panes in editors and terminals keep their focus. A quick calibration sets it up, and it keeps adjusting if you move your chair or your screens. Privacy: frames are processed in memory only. Nothing is recorded or uploaded. It's $5 one-time for 1st 100 licenses with a 14-day refund. I'd love feedback on how accurate it is with your setup!
