Pros & Cons

  • Supports multiple unlock methods (PIN, Pattern, Fingerprint, KnockCode) for flexible security.
  • Includes Spy Camera Protection and Spy Alarm to deter intruders.
  • Fake Error Message and Hide Notifications enhance privacy in daily use.
  • Lightweight, with Smart Settings for battery and RAM efficiency.
  • Competitors emphasize features like privacy-focused vaults, videos, or files; AppLock Pro does not highlight a dedicated vault or media-specific privacy vaulting.
  • Some competitors cover broader privacy controls (e.g., privacy, videos, files) that AppLock Pro does not prominently feature.
  • The app requests a broad set of permissions, including overlay and accessibility services, which may raise privacy considerations for some users; transparency is provided in the Developer Accessibility disclosure.

Accessibility Service disclosure

AppLock's Website Blocker feature uses Android's Accessibility Service to block the websites you choose. When you turn on Website Blocker and grant the permission, the service reads only the web address (URL) shown in your browser's address bar in supported browsers (Google Chrome and Samsung Internet) to detect when you open a site or category you've chosen to block, and then shows a block screen instead of the page.

• It is used only for the Website Blocker feature, and only after you enable it and grant the permission.
• It reads only the address bar (the site's web address). It does not read page content, capture what you type, read your passwords, or record your screen.
• Android does not offer another way for an app to detect the page a browser is showing, so this permission is required for the feature to work.
• You can turn Website Blocker off at any time in the app, or revoke the permission at any time in Android Settings > Accessibility, which stops the service completely.

โ˜…โ˜…โ˜…โ˜…โ˜† Ashraful Islam ยท Oct 27, 2026
It's free and easy to use. Really worth keeping. But most of the time out of nowhere when I want to use any apps there is something happened, my phone stay black app lock pro isn't responding, so I have to close the app, and it's literally disturbing, and I uninstall this app for this reason, and again I am installing it, cause, it's really worth keeping so
โ˜…โ˜…โ˜…โ˜…โ˜… Fred Alarcon ยท Oct 27, 2026
I think ๐Ÿ’ฌ ๐Ÿค” I must have lock apps to prevent my Browser safe specially in ads and viruses, scam, and it might be legal attacks in cyberspace
โ˜…โ˜…โ˜…โ˜…โ˜… Donna Carridice ยท Oct 15, 2026
I like my privacy and this app give me just that
โ˜…โ˜…โ˜…โ˜…โ˜† Tapan Debnath ยท Oct 21, 2026
This app is good. But if it takes you to google Play and you have put a lock on it, you have to use the pin or fingerprint to open it again. Then, if you go back to the original app you were using, you have to unlock it again. That is why I gave 4 stars.
โ˜…โ˜…โ˜†โ˜†โ˜† Foaad Arif ยท Oct 15, 2026
This app was easy to use, but there is a problem in the important time this app show too many ads.......some time. I am fro stated.....
โ˜…โ˜†โ˜†โ˜†โ˜† bejeta ยท Oct 15, 2026
This app prevents the uninstallation of ALL apps, despite advertising being able to lock individual apps. Its own article says that unlocking Settings fixes this, but it does not. Even having only one app locked prevented any app from being uninstalled
โ˜…โ˜†โ˜†โ˜†โ˜† ABHISHEK PATHAK ยท Oct 16, 2026
Just because of why you guys are providing app lock that means you will go to prompt your ad even after locking screen till the lock scren I can understand but what is the meaning after lock screen
