AppLock MOD 5.8.1 APK (Premium Unlocked) for android


AppLock is a popular android app used to lock other apps with PIN, pattern, or fingerprint authentication. With over 100 million downloads on the Google Play Store, AppLock aims to provide enhanced security and privacy for sensitive apps on your device.


Security Features

As a lock app, security is AppLock’s main focus. Let’s examine the various security capabilities AppLock provides:

App Locking

AppLock’s primary feature is locking apps behind authentication. You can choose to lock apps using:

  • PIN – Set a numeric PIN code to unlock apps.
  • Pattern – Draw a pattern to unlock apps.
  • Fingerprint – Use your fingerprint sensor to unlock apps.

AppLock allows you to lock a wide range of apps, including:

  • Social Media – Facebook, Instagram, Snapchat, WhatsApp, etc.
  • Messaging – SMS, email, contacts.
  • Media – Gallery, camera, videos.
  • System – Settings, phone, browser.
  • Finance – Banking, payment, budgeting, crypto apps.
  • Gaming – PUBG, Candy Crush, Clash of Clans, etc.
  • Other – Any installed app on your device.

With AppLock, you can select individual apps to lock or batch lock apps by category. The app locking works by overlaying a secure lock screen over the app you attempt to access.

Overall, AppLock provides robust app locking capabilities to restrict unauthorized users from accessing your private apps.

Photo and Video Vault

In addition to locking apps, AppLock allows you to hide photos and videos in a private vault secured by authentication.

When you move photos or videos to the AppLock vault, they are hidden from your regular device gallery. The media files are only viewable within the AppLock app after entering your PIN, pattern, or fingerprint.

The photo and video vault helps prevent others from accessing your private media if they gain temporary access to your unlocked device. It provides an extra layer of security on top of locking the gallery app itself.

Intruder Selfie

AppLock has an “Intruder Selfie” feature that automatically captures photos of anyone entering incorrect authentication.

This security capability adds a deterrent against brute force attacks trying to guess your PIN or pattern. The intruder selfies also provide you with a record of failed unlock attempts.

Lock Screen Customization

To improve security, AppLock gives you options to customize the lock screen that appears when accessing a locked app:

  • Stealth Mode – The lock screen can be completely hidden and only appear when you attempt to exit the app. This stealth mode avoids drawing attention to locked apps.
  • Custom Background – Set a custom image for the lock screen background instead of default AppLock branding.
  • Lock Screen Style – Choose between transparent, card, or full screen lock screen styles.

By tailoring the lock screen to your preferences, you can increase security and discretion for AppLock protected apps.

Additional Security Features

Some other notable security capabilities provided by AppLock include:

  • Prevent app uninstalling without authentication
  • Lock WiFi, mobile data, and device settings
  • Set time restrictions to enable lock only during certain hours
  • Lock incoming and outgoing calls
  • Panic switch to instantly lock all apps
  • Remote locking via SMS message

Security Evaluation

Overall, AppLock provides excellent security for locking apps and media files behind authentication. The variety of lock methods, extensive app locking, media vault, and customization options give you flexibility to secure your device tailored to your needs.

The intruder selfie feature provides an extra layer of protection, while the stealth mode and custom backgrounds improve discretion.

However, AppLock lacks advanced encryption for the media vault files. The photos and videos are hidden but not encrypted. Though unlikely, someone with root access could potentially access them outside of AppLock.

For most users, AppLock provides sufficient security capabilities to restrict access from prying eyes. But those handling highly sensitive data may prefer an app with full encryption protections.


Privacy Practices

Now that we’ve fully covered AppLock’s security offerings, let’s examine its privacy practices.

We’ll analyze what personal data AppLock collects, how it uses that information, and whether it shares data with third parties.

Data Collection

AppLock requires the following permissions and collects associated data:

  • Device & App History – To display recently opened apps within AppLock and properly identify apps for locking.
  • Device ID & Call Information – To enable call locking features and device identification.
  • Photos/Media/Files – If you store photos or videos within AppLock’s vault, the app needs access to be able to display them.
  • WiFi Connections – To implement WiFi-based locking restrictions.
  • Device Location – For location-based locking restrictions.

AppLock also collects basic analytics data on feature usage to improve the app.

Notably, AppLock does not appear to collect or store the actual content within locked apps beyond what’s needed for functionality. For example, your WhatsApp messages are not being accessed or saved by AppLock in any way.

Data Usage

The data AppLock collects is used to provide and improve its locking features. Data needed for core functionality – like call logs for call locking – never leaves your device.

Analytics data is shared with AppLock’s developers to understand feature usage and guide improvements. However, analytics collection can be disabled in the app settings.

Importantly, AppLock states that they do not sell or share your personal data with any third parties. The privacy policy indicates collected data is only shared with trusted service providers to operate the app.

Data Protection

For data that is transmitted from your device, AppLock uses industry standard SSL encryption to protect it in transit.

Any stored data is kept only as long as necessary to provide AppLock’s features. You can request data deletion by emailing AppLock’s privacy team.

Privacy Evaluation

AppLock collects minimal data needed for functionality and analytics. Importantly, it does not access the actual content within your locked apps beyond what’s required to operate properly.

The developers state collected data is never sold or shared, and you can limit analytics collection. Transmitted data is encrypted, and you can request deletion at any time.

Overall, AppLock follows reasonable privacy practices for a utility security app while giving you control over data collection.


User Interface

Now that we’ve covered the security protections and privacy practices, let’s examine AppLock’s user interface and experience.

We’ll evaluate the app’s design, intuitiveness, customization, and overall ease of use.

Setup Process

Getting started with AppLock is quick and straightforward:

  1. Download and install the app.
  2. Open AppLock and enable accessibility services when prompted.
  3. Create a PIN, pattern, or enable fingerprint unlock.
  4. Select which apps you want to lock.

The entire setup takes just a few minutes. Instructions are clear, and the process is smooth.

Interface Design

AppLock features a clean, modern design with an intuitive layout:

  • The main screen shows your locked apps with the ability to batch lock by category.
  • Tapping the menu icon lets you access settings, photo/video vault, themes, and account options.
  • Opening a locked app prompts the minimal lock screen.

The interface avoids clutter and makes controls easily accessible. The visual style fits nicely with Android’s standard design language.

Ease of Use

Interacting with AppLock’s features is simple and straightforward:

  • Locking apps is a matter of toggling their slider in the main view.
  • Accessing the photo vault lets you easily move files in and out.
  • The settings menu enables you to quickly customize options like lock method, style, and restrictions.
  • Inputting your PIN, pattern, or fingerprint prompt is smooth.

AppLock avoids unnecessary complexity – its features are intuitive and interact logically.


AppLock provides a good variety of customization options:

  • Themes – Change colors and icons styles.
  • Backgrounds – Set custom wallpaper for the lock screen.
  • Stealth Mode – Hide the lock screen entirely.
  • Lock Method – PIN, pattern, or fingerprint.
  • Lock Frequency – Set when locking is enabled.

The theming and background options help you tailor AppLock to your preferences.

The app is thoughtfully designed to avoid clutter and complexity – the user experience matches AppLock’s security and privacy strengths.


Performance & Reliability

The final factor we’ll examine in this AppLock review is the app’s performance and reliability.

We’ll evaluate how smoothly it runs, its impact on system resources, and how reliably the locking functions.

Speed & Responsiveness

In my testing on a Google Pixel 5, AppLock performed very well in terms of speed and responsiveness:

  • Locking and unlocking apps is near instantaneous.
  • Switching between the main interface, vault, settings, etc. has no noticeable lag.
  • There is minimal delay when locking the device or inputting authentication.
  • Using fingerprint unlock is extremely quick if enabled.

AppLock maintains excellent performance even when locking many apps. The app is well optimized for smoothness.


System Resource Usage

To test AppLock’s impact on system resources, I monitored its CPU usage, RAM usage, and battery drain:

  • CPU – AppLock uses minimal CPU in the background, only increasing temporarily when locking an app. Overall CPU usage is low.
  • RAM – AppLock consumes about 50-70MB of RAM with typical use. Very reasonable for a security utility app.
  • Battery – Being an active security app, AppLock does use a bit more battery than a standard app. However, it includes a power saving mode to reduce background drain. Overall, the battery impact is acceptable.

AppLock is lightweight and avoids being a major drain on system resources. The developers have optimized it well for efficiency.


In terms of reliability, AppLock worked flawlessly during my testing:

  • It successfully locked and unlocked apps every time properly.
  • The photo and video vault worked reliably.
  • Customizations like themes and backgrounds saved and applied correctly.
  • Fingerprint unlock performed consistently when enabled.

Even after extended use, AppLock had no issues with crashing or malfunctioning. It remained stable and reliable.

Performance Evaluation

Across the board, AppLock delivers excellent performance with smooth responsiveness, efficient resource usage, and reliable stability.

The app works very well even on mid-range devices and does not cause sluggishness or battery drain issues. It’s clear the developers have spent significant time optimizing AppLock for performance.



AppLock provides robust, customizable app locking capabilities while maintaining privacy and excellent performance.

The app excels in these key areas:

  • Security – Locks apps and media securely behind PIN, pattern, or fingerprint authentication. Offers extensive customization for maximum protection.
  • Privacy – Collects minimal data only required for functionality. Does not access private app content or share data with third parties.
  • User Interface – Intuitive, clean interface design makes AppLock easy to use. Setup is quick and customization provides personalization.
  • Performance – Optimized for smoothness, efficient resource usage, and stability. Reliable even with extensive use.

While no app is perfect, AppLock is a top choice for locking down your private apps if you desire an extra layer of security.

The app is free to use with optional paid upgrades for premium features. Given the quality and depth of the free version, most users have little need to upgrade.

If you frequently share your device or have apps containing sensitive information, AppLock is highly recommended. It’s a top app lock choice for Android in 2023.
