PlainLock

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.
