Protecting an app with a password is the most affordable way to protect your privacy. This article contains the best app locker for Android, which allows you to protect the user’s data from unauthorized users.

What is an application lock?

Application lock is the function of setting a password on selected programs through the control application. You must enter a numeric, graphic, or another type of key to access the locked programs. The function helps block access to applications with confidential information: gallery, messages, phone book, call log, mobile banking, etc.

However, the app lock function via a control program isn’t a complete solution. Such a feature is only in addition to the screen lock and helps protect against curious children or friends who decide to look into a particular application. At the same time, the lock function doesn’t save your vulnerable information in the case of software hacking, phone theft, or technically competent intruders. Therefore, it is better to use the system’s built-in locking methods when it is available.

Avira Security Antivirus & VPN is an antivirus with comprehensive protection, including an app blocking function. To activate the blocking, you need to give the program permission from your device’s administrator and register to be able to reset the blocking.

Three blocking options are available for each blocked app:

– Always – the app is blocked permanently.

– By location – block access to the application in the locations specified on the map.

– By time – block access at a specified time and day.

If you select “always”, you have to enter the specified pattern key each time to access the blocked apps.

The “by location” method locks the selected applications when you visit a specific location, for example, at work or a guest’s place. And it is allowed to set several places on the map.

The option “by the time” sets the time interval of blocking in the specified days of the week. You do not need to drive the key to unlock it on other days.

Additional locking settings are available for permanent locking:

– Lock option – graphic key and pin code.

– Automatic lock – locks the app immediately after the screen is turned off and after a particular interval.

– Advanced settings – prompt to lock new apps and show a fake crash. If you set a “fake glitch”, the screen will show a message about stopping the application and a button to exit. To open the key entry menu, you will need to hold the button for a few seconds.

Main advantages:

– 3 locking options: always, time and place.

Final score:

Avira Security Antivirus & VPN contains three application blocking options. The blocking can be active at all times, activated in certain places, or at certain times. And the presence of a “fake failure demonstration” feature helps make it more difficult for an unauthorized user to access a blocked application.

AppLock

Advanced application blocker.

Features and system requirements:

  • Main features: blocking applications and settings sections, private browser.
  • Blocking options: permanent blocking, in certain locations and by time interval.
  • Pricing: free with aggressive advertising, plans without ads cost 5.14 USD for 3 months and 12.12 USD for 12 months.
  • Android version required: 4.1.
  • Installation space required: 62 Mb.
  • RAM usage: 401 Mb.
  • Application version: 3.7.1.
  • Latest update: December 3, 2021.

The AppLock application locks installed applications, device settings, notifications, and the system interface. The first time you start the app, you need to set a graphic key to unlock it and provide it with permission for “Access to usage history”. The application is available for free but contains aggressive ads: 2-3 full-screen ads with no skip option.

The “Privacy” tab displays the locking applications, and the settings and other locking settings are set in the “Protect” tab. In particular, you can change the initial graphical key or switch to a numeric password. To recover a forgotten password, you can specify an additional question and email. In addition, the function of shooting the front camera in case of incorrect password entry is supported.

In AppLock, permanent locking, time-based locking, and location-based locking are available. When using location binding, you can select a trusted access point. If the phone is connected to the home Wi-Fi network, applications are not blocked. Otherwise, access to the program is automatically blocked.

To make it harder to access a locked application, you can change the AppLock icon in the application menu to a calculator or compass. A “Fake crash demonstration” is supported, where an application error is displayed instead of an unlocked offer and random button placement when entering a numeric password.

Main advantages:

– Availability of permanent locking by time and location binding.

– Application icon masking.

– Capturing the user when he fails to enter the password.

– Availability of a “fake app failure demonstration” function.

Main disadvantages:

– Overly aggressive ads after each action.

– High RAM consumption.

– Requirement to activate an overlay on other windows used to show ads.

– Requirement to provide “Access to usage history” permission.

Final score:

AppLock is a functional app with increased protection for locked apps. The fake malfunction demonstration is a convincing distraction, and taking selfies when you fail to enter your password will help you find out who tried to access the app. That said, AppLock is excessively cluttered with ads, popping up after every action. Requested permissions are used to show ads and collect personal information. And high system resource consumption does not allow using AppLock on low-powered devices.

Perfect App Lock

Application blocker with uninstalls protection.

Features and system requirements:

  • Blocking options: permanent blocking, time interval, blocking when connected to Wi-Fi.
  • Pricing: free with ads, a PRO plan without ads is 2.76 USD.

In Perfect App Lock, applications are locked with a digital password. As an additional security measure, a “Fictitious Fingerprint Scanner” window that appears in front of the password entry window is available for activation. In case a forgotten password is recovered, there is a reset via a pre-registered email.

Perfect App Lock allows you to use a permanent lock, time-based and tethered to a trusted access point. Wi-Fi tethered lock is activated when your device connects to any Wi-Fi access point other than your home network. And time-based locking is active on a set day of the week and time. If you select more than one lock type, “permanent lock” has the highest priority, followed by “Wi-Fi tethering”.

To prevent Perfect App Lock from being uninstalled and to disable the protection, administration activation is provided in the settings. As long as the application is not excluded from the administration list, you can not remove the program. And it is obligatory to manually open the administration menu in the settings.

There is also a watchdog mechanism in Perfect App Lock. After the 3rd unsuccessful attempt to enter a password, the front camera takes a picture of the user trying to access the application.

Perfect App Lock

Main advantages:

– Permanent locking, by time, and by Wi-Fi connection.

– Protection to prevent deletion of the program controlling the blocking.

– Availability of a dummy window for additional protection.

– Shooting front camera in case of unsuccessful password entry.

Main disadvantages:

– Presence of ads.

– Requirement to activate an overlay on other windows used to show ads.

– Requirement to provide “Access to usage history” permission.

Final score:

Perfect App Lock effectively locks applications and prevents you from bypassing the lock by uninstalling the program. In doing so, Perfect App Lock requires granting many permissions, including an administration option that compromises privacy issues.
