AppLock

Lock apps and hide private photos with smart security

AppLock by DoMobile is a focused, privacy-first tool designed to keep curious eyes away from your personal content. Instead of trying to do everything, it concentrates on a single job—locking what matters—and performs it with impressive reliability.

The core feature is app locking. You can protect social networks, messaging tools, email, gallery, calls, and practically any other app with a PIN, pattern, or fingerprint (on supported devices). Once locked, these apps simply won’t open without your chosen code, which is ideal if you often lend your device to friends, kids, or colleagues.

For photos and videos, AppLock offers a private vault. Items moved here disappear from the standard gallery and can only be viewed inside AppLock itself. This is particularly useful for hiding sensitive images or work-related media without cluttering your main photo feed.

Security touches are thoughtfully implemented. The random keyboard and invisible pattern options make it much harder for someone nearby to memorize your code. There’s also a stealth mode that hides the AppLock icon and lets you access it through clever shortcuts like widgets, dialer codes, or from within the gallery, making it less obvious that you’re using extra protection.

In everyday use, AppLock runs quietly in the background and is light on resources, though aggressive battery savers can occasionally interfere with its persistence. As with any app-level lock, someone with full physical access and technical know-how may still attempt workarounds, so it’s best seen as a strong privacy layer rather than an unbreakable shield.

Overall, AppLock is a mature, feature-rich choice for users who want simple, effective control over who sees which parts of their device.
