App Lock

App Lock is an app that aims to lock other apps and prevent unauthorized access. To protect an app, you can choose between a pattern, a four-digit PIN, or a six-digit PIN.

Lock all kinds of apps

App Lock allows you to lock all kinds of apps on your device, including social media apps, such as Instagram, TikTok, or Facebook, or messaging apps, such as WhatsApp, Telegram, Signal, or LINE. You can also protect other system apps like Gallery, Contacts, or Messages.

Enter a PIN or pattern to open an app

Locking an app with App Lock means that whenever you open it, you'll immediately see a lock screen where you must enter a pattern or PIN. After entering it correctly, you'll be able to access the app. App Lock also protects your apps from being uninstalled, as someone could try to uninstall and reinstall them without any protection to access them with your account.

Get intruder selfies

If you want to protect your privacy even more, App Lock has a feature that takes a picture whenever someone unsuccessfully tries to access an app. If they make a mistake when entering the PIN or pattern, the front camera takes a photo saved in the app. Thanks to this, you can find out who tried to access your apps if you have left your Android device unattended for a while.

Hide the app

To stop people from knowing that you have App Lock installed, you can hide the app and replace the icon with another generic app, confusing anyone using your device without your permission.

Remove junk files

Finally, App Lock has additional features, such as deleting accumulated junk files on your device and also customizing the app's theme.
