About

Chain Scroll

You quit smoking. You can quit scrolling. Chain Scroll treats your phone like a pack of cigarettes. Pick the apps you open without thinking and every time you “light one up” it buys you a 3-minute scroll break like your old smoke break. When it's out, the app locks back up and the pack shows one less scroll. HOW IT WORKS • Built on Apple's Screen Time. Chain Scroll never watches you • Each open of a trigger app = one light-up from today's pack • A light-up lasts 3 minutes then re-locks (though you can set the duration of your choice) THE RITUAL • Home Screen widget • Dynamic Island countdown • The Carton Review: your week in packs • Blends: reskin your pack • Lighter Mode: pair an NFC sticker as your physical “lighter” and tap it to light up PRIVATE BY DESIGN No account. No analytics. No server. Apple's privacy design means we can't even see which apps you pick. Everything stays on your device. FREE AND PAID Free: the full core mechanic on one app, plus both widgets. Or try everything free for 30 days and keep it all with a single one-time purchase. No subscription, ever.
