AppLock: Lock Apps with PIN

AppLock protects the apps you choose: chats, photos, gallery, social, email or any other app. When someone tries to open them, the unlock screen appears first.

For each app you choose how it unlocks:
• PIN: the AppLock master PIN, with a round keypad
• Password: a secret word you choose
• Fingerprint: with the phone's sensor, and the PIN as a backup
• Math: solve a sum to get in (easy, medium or hard)
• Time window: during the hours you choose (for example 10 pm to 7 am) the app does not open at all

Also:
• After unlocking, the app stays open until you switch to another app or turn off the screen
• AppLock itself is protected by the master PIN
• After 5 wrong attempts there is a 30-second pause
• PIN and password are never stored in plain text
• Dark or light theme, 10 languages

Free: up to 3 locked apps. Watch a short video to lock as many apps as you like and remove ads for 24 hours. The unlock screen shows a small banner, away from the keys.

AppLock uses the Android accessibility service only to know which app is opening and show the unlock screen. It does not read screen content or what you type. No account and no server: your rules stay on your phone.

AppLock cannot stop the phone's owner from uninstalling it or turning off the service in the settings.
