If you are familiar with Go Launcher, Apex Launcher should not be any different.

Tech reviewers agree that Applock by DoMobile Lab is one of the notable app lockers in the market today. It integrates two features; one, it locks apps that you otherwise wouldn’t want others to have access to. And second, it also acts as a vault-app, locking your private photos and videos in a private folder. Access can only be granted by providing a master lock pattern and biometrics. But what we love about this app is its ability to lock even incoming calls, uninstalling apps that you otherwise didn’t authorize, and is 100% free to download on Google Play Store.

It has the ability to lock both system apps and social apps. On top of that, it is also powerful in locking Android Pay, Samsung Pay, Paypal, and so on.

Malware Issues: Are App Locks Safe?

Reports have emerged detailing how hacks and digital theft have been conducted in recent years. While privacy vault apps and app lock apps are there to offer a blanket of security from hackers, some offer the complete opposite. A number of these apps do resemble how Trojan and malware viruses operate — they spy on you and sell your data to state actors.

So, are app lockers safe? The answer is somewhere in the middle. It also boils down to one question: Why do you need an app lock app? Privacy concerns are a valid reason. But there are other safer alternatives to address this concern. Try backing up your data on Google Drive and delete the data on your phone. Saving files to external hard drives is another alternative if you wish to keep private files from prying eyes.

Whatever our reasons might be for getting an app lock app, it is important to put other users’ reviews into consideration and how well the app is fairing in the market. A little research will do us no harm.



App lockers surely do give our smartphones a sense of leverage against those who try to break into our personal space. Luckily, Android app developers found a solution and have given us a number of options to choose from. We hope this article gave you insights into what app lockers really are, what they do, as well as their pros and cons. Now, go arm your phones with this security feature and let us know which app did the best trick for you!
