Stop doomscrolling before another hour disappears. Most blockers just lock you out and get bypassed in seconds. SmartScroll is different: when your limit is reached on Tiktok, Reels, Shorts, or any endless feed, it interrupts the loop and replaces it with quick knowledge cards. Something better to do, right at the moment your brain wants "one more video." Why people use SmartScroll: - Interrupt doomscrolling before it spirals - Block TikTok, Instagram, YouTube Shorts, X, and more after daily limits are reached - Replace mindless scrolling with bite-sized knowledge you’ll actually remember - Add friction when automatic scrolling takes over - Visualize wasted screen time with Life Grid - Build healthier phone habits without deleting social media Core features: - Automatic app blocking after your limits are reached - Smart interruption flow that breaks scrolling momentum - Bite-sized knowledge cards for quick, useful learning - Custom app limits and schedules - Life Grid to visualize time lost and time reclaimed SmartScroll is for people who: - Open social media without thinking - Lose an hour checking “one thing” - Feel mentally drained after short-form videos - Have tried timers, willpower, or basic blockers without success • Want healthier phone habits without quitting social media Your apps are not the problem. The automatic scrolling loop is. SmartScroll helps you break it. Download SmartScroll for free. Premium features require an in-app purchase.

About

Cairn

Stack before you scroll. Cairn helps you stop scrolling by adding one small pause before distracting apps open. Choose the apps you want to protect. When you reach for one, iOS shows a Screen Time shield. Open Cairn, build the requested stone structure, and earn a short window to continue. It is enough to break the reflex. Often, that is all you needed. What's in Cairn - Stack: balance stones into target structures before the app opens. - Short unlock windows: earn a few intentional minutes, then the shield returns. - Multiple rituals: Stack, Breath, Trace, Walk, and Untie. - Stone styles: granite, basalt, riverstone, obsidian, marble, moss, and moonstone. - Sunday reflection: save a private weekly reflection about the pauses you kept. - Lock Screen widget: see minutes reclaimed today at a glance. Built for focus - Uses Apple's Screen Time controls for app blocking. - No account. - No cloud. - No ads. - Your watched-app list stays on your device. - Haptics, sound, and calm visual design built around one idea: interrupt the reach before it becomes a scroll. Free Cairn includes core blocking and daily stack rituals. Cairn Pro unlocks deeper rituals, stone styles, custom unlock windows, weekly reflection, and more ways to hold the trail. Cairn is not a dashboard for judging your phone use. It is a small threshold between impulse and action.
