## What is 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.


## Version history (last 5 releases)

### 1.6.5 — 2026-08-16

Fixed temporary access for category blocks: notifications and the cooling-off period now appear correctly, and the category is blocked again when the usage allowance ends. When a daily limit has been reached, returning to PlainLock now confirms that the block is still active.

### 1.6.4 — 2026-08-13

• Added Traditional Chinese, English, Japanese, and Spanish interfaces, with localized status, diagnostics, and version history.
• Groups now support up to 50 apps, with a clear message when the limit is exceeded.
• Fixed cooling-off notifications: the Shield closes first, then the alert appears one second later to reduce delays and system-interface freezes.

### 1.5.1 — 2026-08-08

修正時段封鎖偶爾看似正常、實際卻沒有擋住 App 的問題。

 - 如果系統排程仍在，但封鎖狀態意外消失，回到 PlainLock 時會自動補回目前該生效的封鎖。
 - 補回封鎖時，已完成冷靜期取得的暫時開放不會被提早收回。
 - 讓「我明明設好了，怎麼還是滑得進去」少一個發生的機會。

### 1.5.0 — 2026-08-03

規則列表新增「今日狀態」，現在可以直接查看每日額度約剩多少分鐘、額度是否已用完，以及時段封鎖何時開始或結束。
同時強化排程對帳、跨日重設與暫時開放的穩定性。

### 1.4.2 — 2026-08-02

這次更新加強暫時開放與重新上鎖流程的穩定性。

如果系統狀態異常，PlainLock 會優先維持封鎖，避免規則意外失效。App 回到前景與系統排程觸發時，也會更確實確認
封鎖規則是否已套用。狀態檢查頁也補強了診斷資訊，遇到問題時更容易排查。
