5 Android App Lockers That Easily Take the Cake

When it comes to security, Android has frequently drawn criticism not only from the market experts, but also from its users. Its security features are often compared to that of iPhone, which has let it known time and time again that it takes the privacy and security of its users very seriously. Lacking faith in Android’s built-in security features, users turn to third-party solutions like lockers to keep their private data from falling into the wrong hands. So far, this seems to be working really well for them.

What is an App Locker?

App lockers are apps that are specially designed to lock different apps in order to prevent unsolicited access to personal data on mobile device. These apps are also commonly used by users to increase the security of their smartphones. Most of these apps are available free of cost, though some need to be purchased. App lockers use password, pin, pattern or gestures to lock different apps like SMS, Contacts, Gallery, Facebook, WhatsApp, Skype, Emails, etc.

What to Expect from a Great App Locker

There are a large number of app lockers available on Google Play Store and other app stores, but not all of them are worth using.

Lock SMS and Contacts

Nobody is comfortable with others going through their SMS or contact list as it’s something really private. App lockers offer a peace of mind by blocking access to them.

Lock Calls

People, especially kids, can often grab the phone and make or attend calls even though they are not allowed to do so. App lockers can also restrict access to the Call app.

Lock Gallery

App lockers can block access to gallery, thus guarding the private pictures and videos of users.

Multiple Lock Options

Some app lockers allow users to secure device and data by offering multiple lock options such as password, pin, gesture, or a pattern.

User-Friendly Interface

A user-friendly interface is particularly important for users who are not very tech-savvy. A simple interface makes the app locker more accessible.


There are various versions of Android available in the market. Therefore, it is important to check the compatibility of an app locker before investing in one.

Uninstallation Prevention

Some app lockers come with uninstallation prevention so that kids or snoops can’t remove them from the device to gain access to protected data.
