AppLock6.3.3

AppLock lets you put access controls on selected Android apps and personal content, keeping other people from opening them without the chosen lock. It is designed for private-use situations involving apps such as Facebook, WhatsApp, Gallery, Messenger, Snapchat, Instagram, SMS, Contacts, Gmail, and Settings. Incoming calls can also be locked, and the same protection can be applied to any other app you select.

Its photo and video vault provides a separate place for private media, hiding stored items from the regular Gallery while keeping them viewable inside the vault. A random keyboard disguises the arrangement of passcode keys, while an invisible pattern lock conceals the pattern used to unlock protected content. The interface supports 45 languages, allowing the app to serve users across that language set.

AppLock suits people sharing a phone, lending it to others, or keeping personal conversations, contacts, media, and account-related apps private. It is an Android System Tools release, and the current version is 6.3.3.

In this release, the functions have been optimized and the overall experience improved.

Free to use — a paid version with additional features is also available.
