About this app

Safeguard your privacy, lock contacts, messengers & other apps with AppLock

Packed with powerful functionality and slick UI, AppLock is the top locking app that enables you to protect your data and lock apps from intruders in a matter of few clicks.

How does AppLock work?

Having configured the basic AppLock settings upon the first sign-in, you only need to open AppLock and tap the app - to switch on the app lock protection.

Key features:
• Powerful Message Locker
Lock Facebook Messenger, WhatsApp, Viber, Snapchat, WeChat, Hangouts, Skype, Slack and other messenger apps with AppLock to ensure your conversations with family, friends, and colleagues stay protected.
• Advanced AppLock for System Apps
Lock contacts, calendar and other system applications in a flash - using AppLock.
• Broad Range of App Lock Options
AppLock enables you to select the best lock option for your apps, i.e. lock apps with fingerprint, password or pattern you set up.
• Random Keyboard
Switch on a “Random Keyboard” feature in AppLock to hide your password from prying eyes.
• Intruder Selfie
Turn on the “Intruder Selfie” mode in AppLock and track who’s made unauthorized attempts to snoop into your phone.
• Optimized Battery Power Usage
AppLock is optimized for the minimum battery power consumption, by default.
• Real-time App Lock Protection
AppLock will notify you of the new app/s on a device, available for locking.
• Customizable Themes
Personalize your experience with AppLock by selecting a Light (Default), or a Dark theme.

AppLock requires the following app permissions:
• App Usage - used to retrieve the list of installed apps, available for locking, and manage their lock status.
• Overlay (Run over other apps) - enables the lock screen display. Note! The “Overlay” permission is mandatory for Android 10 smartphones and tablets - otherwise, AppLock won’t work on the device.
• Camera - used to make an intruder selfie.

Getting Started with AppLock:
AppLock enables you to configure a broad range of settings right away - the first time you’re using the app. Let’s see how it works.
• Open AppLock.
• Grant the required “App Usage” and “Overlay” app permissions.
• Sign in the app using your Google account. Note! Sign-in is required to enable recovering access to locked apps in case you forget your AppLock lock password or pattern.
• Select & configure the app lock option you’d like to apply. Tip! If you’re using the Password (PIN) lock, it’s also possible to switch on the “Random Keyboard” feature right away.

Configure a number of extra stability and security features:
• Enable advanced app lock protection - set AppLock as a device administrator to prevent the app from authorized uninstall attempts.
• Disable battery optimization - switch on this feature to prevent AppLock from sleeping and ensure stable app lock protection.
• Set Fingerprint App Unlock - enable unlocking apps instantly, with a fingerprint.
• Switch on “Intruder Selfie”- turn on the feature to enable the app to take photos using the front camera on your device, in case the incorrect AppLock Password (PIN) or Pattern is entered.

App is designed very attentive But I found a problem that when pattern or pin is displayed to unlock an app then I am stucked on that as I can't go back via back button There remains only option is either go to Home screen or open tasks that leads to closing the running application.. and this irritated me more I hope you understand..

The AppLock only has limited amount of apps that you can lock it doesn't matter what apps though but I installed it and it said go premium which made no sense because all the other app blocks that I've tried are way better than this because there is not limited app that you can lock. Do not recommend unless you are origin willing to pay $99 a year.
