AppLock Master - Protect App for Android

Overview

AppLock Master is a free Android utility focused on strengthening privacy for apps and personal files. It helps prevent unauthorized access to messaging, social, and finance apps, and provides tools to keep sensitive media out of sight.

Notable capabilities

• Intruder selfie: automatically snaps a picture when someone fails to unlock a protected app.
• App locking methods: supports PINs and pattern locks to block access to apps such as WhatsApp, Instagram and banking software.
• Hidden icon mode: lets the app masquerade as an innocuous program (for example, a calculator) to avoid drawing attention.
• Private media vault: stores photos and videos in a concealed area separate from the main gallery.

Camouflage options

AppLock Master can disguise itself so its presence is less obvious on the device. By changing its appearance to a harmless utility, it reduces the chance that others will try to open it or discover protected content.

Protecting photos and videos

The built-in vault isolates selected images and clips from the phone’s gallery. Media placed in the vault won’t appear alongside regular photos and must be accessed through the app’s protection mechanisms.

Intrusion alerts

When someone attempts to bypass protections, the app can record the event and capture an image of the person who tried to unlock the app, giving you visibility into unauthorized attempts.
