A break reminder for when you've been staring at a screen too long.
Gently interrupting the “just five more minutes” spiral.
SpellBreak watches for specific apps you tend to disappear into, using Android's Accessibility Service, and gently overlays a break prompt after a while spent in them. Tap “just browsing” and it backs off for a cooldown period — but it has to actually stay off, which turned out to be the hard part.
The “just five more minutes” spiral is real, and easy to lose an evening to. SpellBreak's whole job is to notice it happening and interrupt it gently — but a prompt that fires at the wrong moment (or reappears right after you've left) trains people to ignore it, which is exactly what the recent exit-echo fix was protecting against.
Built directly on Android's Accessibility Service, in Java.
