AppLock Fingerprint App Locker

AppLock is a fast, lightweight app locker for Android that lets you lock apps with fingerprint, PIN, pattern or password. Protect WhatsApp, Instagram, Facebook, Gallery, banking apps and any other app on your phone, hide private photos and videos in an encrypted photo vault, catch intruders with a selfie, and lock new apps automatically. App Lock keeps your personal information safe from anyone who picks up your phone, whether it's a friend, family member or child.

LOCK ANY APP
Choose exactly which apps to lock. Use WhatsApp lock to keep your chats private, and protect Messenger, Telegram and Signal the same way. Lock social media apps like Instagram, Facebook, Snapchat, TikTok and X. Gallery lock keeps your photos and videos away from prying eyes, and you can lock banking apps, payment apps, Gmail and Messages with a fingerprint or PIN. Lock Settings to prevent unwanted changes and lock the Play Store to stop kids making accidental purchases.

FINGERPRINT, PIN, PATTERN OR PASSWORD
- Fingerprint lock for fast, secure unlocking on supported devices
- PIN lock with a randomized keypad to prevent shoulder surfing
- Pattern lock with the option to hide the pattern while you draw
- Password lock for an alphanumeric code

INTRUDER SELFIE
When someone enters the wrong PIN, pattern or password, App Lock silently takes a photo with the front camera so you know who tried to break into your apps.

PHOTO VAULT
Hide photos and hide videos in a secure, encrypted vault. Files moved to the vault are removed from Gallery and can only be viewed inside App Lock with your fingerprint or PIN.

UNINSTALL PROTECTION
Prevent anyone from uninstalling App Lock without your PIN, pattern or password, so your app lock cannot be bypassed.

FAKE CRASH COVER
Show a fake "app has stopped" error on top of a locked app instead of a lock screen. Nobody knows the app is locked, and only you know how to dismiss the fake crash dialog and open it.

DISGUISE ICON
Change the AppLock icon to look like a calculator or another everyday app so nobody realises you are using an app locker.

MORE FEATURES
- Lock new apps automatically with one tap when they are installed
- Over 100 lock screen themes to customise your app lock
- Password recovery so you are never locked out of your own apps
