For everyone who can't stop saying "just one more scroll." AcornLock is a self-control app that uses Apple's official Screen Time API to genuinely block the apps you choose. What makes it different from typical app blockers? There's a real cost to unlocking. When you crave the apps you've locked, just shake your phone. They'll unlock for a set time—but at a price. The acorns your squirrel has been quietly collecting? Some of them vanish at random. "Wait, did I just lose my rare one…?" That moment of loss puts a gentle brake on your impulses. Tired of apps that only ask you to grit your teeth and resist? AcornLock turns the time you don't spend on your phone into something worth collecting. Built for people who: ・Lose hours to Instagram, TikTok, X, or YouTube ・Want to change habits through gameplay, not pure willpower ・Love collecting cute things CORE FEATURES ■ Real blocking with Screen Time control Powered by Apple's official Family Controls API, your chosen apps are blocked the moment you hit your limit. No relying on willpower alone. ■ A squirrel that collects for you While your selected apps are under restriction, a squirrel quietly gathers acorns in the background. They pile up while you live your life. ■ Shake to unlock = lose your acorns To unlock, just shake your phone. But 50% of your unjarred acorns vanish at random. ■ Collect acorns From everyday brown acorns to legendary rainbow ones, every drop is a small surprise. ■ Seal them in jars for permanent safekeeping Reach 50 acorns and you can seal them in a jar. Jarred acorns are safe forever, even when you shake to unlock. ■ A wooden shelf of your wins Completed jars line up on your wooden shelf, a visible record of your self-discipline. One jar = about a week of staying strong. REWARDS FOR STICKING WITH IT ・Streaks: Every day you stay under the limit adds to your streak ・Tier 0 to 5: Climb the tiers as your streak grows, boosting your odds of rare acorns FLEXIBLE LIMIT SETTINGS ・Pick multiple apps and categories with Apple's Family Activity Picker ・Set your daily time limit however you want ・Adjust how long the unlock lasts before the block returns ・Choose between Shake or Scratch unlock methods PREMIUM For people serious about changing: ・Hard Mode: Triple the unlock barrier. Lose 100% of your unjarred acorns on every unlock. ・Streak Protection: Auto-saves your streak once a month if you slip ・Larger Acorn Stock: Hold up to 500 acorns instead of the free 50 ・Unlimited Shelf Display: See every jar you've ever made ・Choose from three plans: weekly, yearly, or one-time purchase MORE FEATURES Keep an eye on your acorn count and streak right from your Home Screen widget. Take back the distance between you and your phone, one acorn at a time.

About

PlainLock

Features
Read full description

PlainLock is a deliberately simple screen-time self-control tool. TWO WAYS TO SET A LIMIT • Schedule blocks: choose days and times, then the selected apps are blocked. • Daily limits: after the minutes you set are used, the apps stay blocked until tomorrow. • Shared group limits: put distracting apps in one group so switching apps cannot bypass the limit. • Group app limit: each group supports up to 50 apps, with a clear message when the limit is exceeded. • Cooling-off period: when you really need temporary access, wait 5 seconds, then unlock for the short duration you chose. LANGUAGES • Available in Traditional Chinese, English, Japanese, and Spanish. READ BEFORE YOU BUY • One purchase. No subscription. No in-app purchases. • Every rule stays on your device. The app makes no network requests and collects no app data. • This is a self-control tool, not a security tool. You can always remove restrictions by disabling its Screen Time permission in Settings. • Applying or clearing a block depends on iOS scheduling and can take one to two minutes. • Requires iOS 17.0 or later. Only iOS versions tested at release are supported; future compatibility and continuing updates are not guaranteed.
