What AppLock is for

AppLock is an Android app lock. It puts a PIN or pattern in front of apps you pick, and it can also hide photos and videos. The listing aims it at people who share a phone with family, coworkers or children, and at anyone who wants private messages and pictures kept out of sight.

The listing also describes it for stopping a child from changing Settings or sending messages, and for keeping a friend from opening a phone's games and paying in them. The developer lists 45 languages for the interface.

Locking apps such as WhatsApp, Gmail and Settings

The listing names a set of apps that AppLock can lock: Facebook, WhatsApp, Gallery, Messenger, Snapchat, Instagram, SMS, Contacts, Gmail and Settings. It can also lock incoming calls and any other app you choose.

Locking Gallery and Settings covers two common cases on a shared phone: someone scrolling through your photos, or someone changing system settings. Locking SMS and Contacts covers messages and numbers.

Hiding photos and videos in a vault

Pictures and videos you hide are removed from Gallery. They are only visible in the photo and video vault, which AppLock opens behind its own lock.

The listing presents this as a way to keep personal photos and videos away from anyone who picks up the phone and opens Gallery.

Unlock methods: random keyboard and invisible pattern

AppLock offers a random-layout keyboard for entering the PIN, so the digits you tap are not in a fixed place on screen. It also offers an invisible pattern lock as a second unlock method. The developer's stated reason for both is to stop people nearby from seeing the PIN or pattern.

To change the password, open AppLock, go to the Protect tab and choose Unlock Settings.
