Lock N' Learn is a parent-installed iPhone and iPad app. After the child unlocks the device as usual, selected apps stay shielded until they write a Chinese character from 注音.

It does not replace the iOS lock screen. Phone and Emergency SOS stay available. Apple can re-lock shielded apps no sooner than 15 minutes.

No account. No ads. A parent PIN protects settings.

「鎖上學」是給家長安裝的 iPhone / iPad App。孩子用原本的方式解鎖手機後，選定的 App 會先鎖住，看注音、寫出漢字，才能打開。

不會取代 iOS 鎖定畫面。電話和緊急求救永遠可用。Apple 最快 15 分鐘後才會再鎖上。

不用註冊，沒有廣告。家長設定有 4 位密碼保護。
