Lock Apps - AppLock Master

App lock for everything on your phone that should stay yours. Choose the apps you want kept private and AppLock Master holds them behind a PIN, a pattern or your fingerprint, so your messages, your photos and your banking apps open for you and for nobody else.

Lock apps in about thirty seconds. Tick the apps you want protected, set a passcode, and the app lock does the rest from then on.

🔒 Lock Apps
Put an app lock on WhatsApp, Instagram, your gallery, messages, email, settings and banking apps — on anything you have installed. Pick a password lock, a pattern lock or a fingerprint lock, and change your mind whenever you like. Switch on auto-lock and every app you install from that moment arrives already locked.

🔔 Notification History
Notifications you have already dismissed are still readable. AppLock Master keeps a history of what arrived, so the message you swiped away by mistake is waiting for you instead of gone. Look back through the day and see what came in while your phone was in your pocket.

🚫 Notification Blocker
Choose apps whose notifications never reach the shade at all. Nothing previews on your lock screen, nothing lights up while your phone is face-up on a table, and the content is readable only inside the app lock, where your passcode is the way in.

🌐 Private Browser
Browse in a private browser with an ad blocker built in. No history is kept, closing a tab leaves nothing behind, and ads and trackers are blocked as the page loads — so pages come up faster and use less of your data.

📸 Intruder Selfie
When someone gets the passcode wrong, the front camera takes a quiet photo and stamps it with the time. You come back to your phone knowing who picked it up, and when they tried.

🛡️ Uninstall Protection
Nobody takes the app lock off behind your back. Your passcode is asked for before the uninstall screen opens and before the permission screens can be changed.

🎭 Icon Camouflage
Change the launcher icon and the name it appears under. The app lock can sit on your home screen looking like a calculator rather than announcing what it is.

🎨 Lock Screen Themes
Choose a theme, a colour and a background for the unlock screen. Hide the pattern lines as you draw them, and decide how quickly the app lock closes again once the screen goes dark.

Why AppLock Master
• Lock apps, notification history, notification blocker and a private browser in one app
• Password lock, pattern lock and fingerprint lock, whichever suits you
• Ad blocker for faster browsing that leaves no trace
• Light, quick and easy on the battery
• Your data stays on your device

📱 What you can lock
WhatsApp lock, Instagram lock, Facebook and Messenger, gallery lock, messages, email, banking and payment apps, settings, Play Store, camera and file manager. Nothing is left off the list: every app on your phone can be given an app lock.

🔐 Password, pattern or fingerprint
All three open the app lock, and you can move between them at any time. If you use a pattern lock, hide the lines so nobody reads them over your shoulder. On supported devices a fingerprint opens the app lock with a single touch. Forget your passcode and a security question gets you back in.

⚡ Light and fast
The app lock runs quietly in the background. It does not slow your phone down, it does not drain the battery, and the unlock screen appears the instant you open a protected app.

Privacy and permissions
The app lock needs Usage Access and permission to display over other apps in order to work at all. Notification access is requested for notification history and the notification blocker. Camera permission is used only while Intruder Selfie is switched on. Biometric unlock depends on your device and your Android version.
