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.
