AppLock Pro - App Lock & Guard

App-level privacy controls

AppLock Pro - App Lock & Guard adds a separate lock to the apps you choose, making it useful for anyone who shares a phone or wants extra control over private content. You can protect messaging, social, gallery, settings and other apps with a PIN, pattern, KnockCode or fingerprint where the device supports it.

More than a basic lock screen

The app can hide notifications from protected apps, re-lock them after a short period and pause locking during selected hours. It can also show a fake error message instead of a normal lock prompt. These options are practical when you want privacy without constantly entering a code during routine phone use.

Alerts for failed access

For stronger monitoring, AppLock Pro can sound an alarm after repeated incorrect attempts and use the front camera to capture a photo of a suspected snooper. The app also includes controls for locking recent apps, warning about newly installed apps and adjusting vibration. Custom backgrounds and themes change the appearance, but the main purpose remains access control.

Widely used productivity utility

Developed by App Lock LLC, AppLock Pro is listed in Productivity and has a 4.34 rating from more than 1.9 million reviews, with 100,000,000+ installs. It suits people who need a straightforward way to put another barrier around selected apps and media, rather than a full device-security suite.
