Description by Chang Jhih Yeh (from the App Store)

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.
