Someone borrows your phone to make a call or look at a photo. AppLocker keeps everything else shut: your chats, gallery and banking ask for your PIN or pattern. It doesn't use Accessibility, the permission that can read your whole screen and that most app lockers ask for. No account, and your PIN never leaves the phone. If someone guesses wrong, Pro quietly takes their photo and shows the code they tried. Kids Mode leaves only the apps you allow. Free for 3 apps (with ads).
