Lock App - Smart App Locker for Android

Compact mobile app protector (Lock App — Smart App Locker)

Lock App — Smart App Locker is a lightweight, free productivity tool for Android created by Anuj Tenani. It serves as an application locker that prevents unauthorized access to apps and games by enforcing entry controls. The utility is designed to be simple, fast, and unobtrusive, offering multiple ways to protect your installed software.

Protection methods available

Choose from several authentication options to secure individual apps:

• Pattern lock
• PIN code
• Password
• Fingerprint (biometric) support

You can apply any one of these methods to each app you want to protect. In addition to locking, the app lets you hide its own icon so it won’t appear in the device’s app list.

Interface and how to use it

The layout is straightforward and tab-driven. Two main tabs organize the app:

• Locked Apps — shows which applications currently have protection enabled
• All Apps — lists every installed app so you can pick which ones to lock

Select an app from the All Apps tab, then assign your preferred lock type (pattern, PIN, password, or fingerprint) to secure it. The interface is designed to be intuitive so setup is quick even for first-time users.

Performance notes and limitations

Overall the app runs smoothly and is light on system resources. One minor issue to be aware of: some locked applications may display brief graphical glitches the first time they are opened after locking. Apart from that occasional visual hiccup, functionality is stable and reliable.

Conclusion

If you want a no-frills app locker that does what it promises, Lock App — Smart App Locker is a solid choice. It’s easy to use, quick to configure, and completely free without advertising interruptions, making it a convenient option for protecting your privacy.
