Cairn
Read full descriptionHide full description
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.

CTRL is a focus timer, app blocker, and habit builder in one. The rule is simple: you earn credits by focusing, and you spend them to open the apps that steal your hours. Run out, and the scroll stops until you put in the work. It turns willpower into an economy so you don't have to rely on willpower at all. WHY CTRL WORKS WHEN OTHER FOCUS APPS DON'T Most productivity and screen time apps just block apps and hope you don't switch them off. CTRL doesn't fight your dopamine it puts a price on it. Every distraction costs credits you can only earn through real focused work. That's what makes the habit stick. FOCUS TO EARN • Run focus sessions (25, 50, or 90 minutes) and bank credits • Keep your phone face-down during a session for a +50% bonus • Longer, distraction-free deep work pays the most • Build a daily focus habit and track your time like a pro BLOCK THE APPS THAT EAT YOUR TIME • Shield TikTok, Instagram, YouTube, Reddit, X and more using Apple Screen Time • Block distracting websites too, so Safari can't reopen the same feeds (Pro) • The most addictive apps cost the most credits to open PAY TO OPEN — EVERY TIME • Before a blocked app opens, CTRL asks why and charges you credits • Every "I'm bored" tap is logged, so you get a real distraction tracker for your worst habits • See your triggers and take back control of your attention RECOVERY MODE FOR THE HARD DAYS • Binge patterns automatically trigger a fairer economy: earn more, spend less • Miss a day and a freeze covers your streak — built to catch the spiral, not punish it HONEST BY DESIGN • Credits are earned by focusing never bought with money • Your Screen Time data never leaves your device. CTRL can't see which apps you use. • No ads. No tracking. No account or login required. MADE FOR Anyone fighting phone addiction, doomscrolling, and procrastination students, founders, writers, remote workers, and anyone who wants focus, productivity, and self-control on their own terms. A focus app, app blocker, screen time limiter, distraction blocker, and habit tracker rolled into one. CTRL PRO Upgrade to block unlimited apps and websites, schedule unlimited unlock windows, and more. Monthly or annual, with a 7-day free trial on the annual plan. Use it, but pay for it.
