App Locker

Looking for a simple way to lock your apps and protect your privacy?

App Locker by Mongolian Lab is a lightweight, no-nonsense security tool designed to help you lock down any app on your Android device in just a few taps. Whether you want to keep your messages private, hide your gallery, or prevent kids from opening certain apps, this app gives you full control without the bloat.

How It Works

The core workflow is refreshingly straightforward. After installation, you set a master password — choose a simple PIN or a complex alphanumeric code, whatever suits your security needs. Once your password is active, you simply select the apps you want to protect from your installed list. From that moment on, anyone trying to open a locked app will be prompted to enter the password.

You can also protect specific videos directly from within the app. No need to dig through folders or third-party file managers — just add video files to the lock list and manage them all in one place.
