App Lock - Lock & Unlock Apps is a free utility tool developed by Lara Pollar. This app locker lets users employ security measures to prevent access to their apps by other people. It supports virtually all apps ranging from productivity to social media, and others.

Similar to other solutions like Lock App - Smart App Locker or Pop Locker - Hide Secret App, App Lock - Lock & Unlock Apps boasts a simple and user-friendly interface. It offers multiple locking methods to keep applications secure and other handy extra features that users can take advantage of.

Access control

App Lock - Lock & Unlock Apps starts with the app locker that can be utilized in three ways. The first is enabling notification protection to prevent alerts from appearing. Second is the intruder function that lets you camouflage applications with custom icons and names. Thirdly, you can enable the intruder mode to have the app take a photo of someone trying to open an app.

The second core feature is the Vault, which is a section where you can store sensitive data that you don't want anyone else to see. It covers all kinds of media, from audio to video and photos. What's more, it supports regular files like documents, so they can be kept secure and prevent them from being opened and viewed by others.

As a bonus feature, the app also has a built-in browser especially made for private web browsing to keep your online identity, traffic, and location anonymous. As for setting up locks, you can choose from the standard PIN, pattern, or fingerprint authentication to gain access to your locked applications. One major concern, though, is that the app tends to randomly close in the background.

Secure apps and more

All in all, App Lock - Lock & Unlock Apps is a handy utility tool that not only lets you secure your favorite app from others but also lets you store your sensitive data for safekeeping. It looks clean, is easy to use, and offers plenty of utility for what it is. A slight setback is that it will randomly close in the background. Still, it's worth giving it a try and test its features for yourself.
