Top 5 Android Apps That Can Help You Lock Your Apps

Android is the most popular smartphone OS as it boasts the user-friendly features. The security of your Android Smartphone is something you should take very seriously.

Even though the Android phones come with several screen locking features that would let you add a password to lock the phone screen, you probably have several apps installed on your Android Smartphone that hold private and sensitive data that you may want to protect.

However, you cannot effectively protect your apps if you simply enable the default security password or pattern lock because this will merely prevent unauthorized individuals from accessing your Smartphone.

This can also be somewhat of a hassle and an inconvenience. So, how to secure the sensitive information that stored in your Android phone from falling into wrong hands?

A much more convenient, foolproof way to lock and password protect specific, individual apps on your Android Smartphone is to use one of the following apps:

1. LEO Privacy Guard

LEO Privacy Guard will provide you three different ways to ensure privacy, namely Dot/Pattern Lock, Passcode and Touch ID that will recognize your fingerprint.

Besides, this exciting app will also provide you a Private Camera option, so any personal/private photos you want to keep hidden/locked will be automatically stored in a private album. You can also store sensitive personal information, such as credit card info, in the app’s Safe Box. Download this app from Google play.

It has a device monitor to watch your data usage and supports Apple watch as well.

2. AppLock

Unlike all of the apps reviewed above, Visidon Applock App will use facial recognition technology to lock your apps. An alternative password also has to be set up for instance where facial recognition fails. However, in most instances this app successfully recognizes the registered face.

Adding the app to Device Administrators will also ensure that no one is able to delete it. You can even purchase its paid version, which happens to be free of advertisements. So, I would say that it a cool app to enhance the safety of your private phone apps.


The usage of smartphone has increased a lot as we have started utilizing it to surf the net, shop online, pay bills, bank transactions and much more. You might have personal data in the Gallery, Message and Mail on your Android phone that needs protection.

You can conveniently download these apps from the Google App Store for free and start protecting your phone apps.

  • Hi Atish,
    Yet another post on Android phones.
    Yes, the use of these phones are increasing day by day and the security too is a big problem.
    The different apps mentioned in this post is really a handy one for who uses many different apps on their phones.
    But Atish, in relation to locking the screen there are several inbuilt screen locking features that would let add a password to lock the phone screen, but i think that is a danger though it gives some privacy security, in an emergency case if someone want to inform about the owner of the phone it is a difficult thing to unlock the system. so it is better not to lock the screen, but in the case of App I feel it gives more protection.
    Thanks a lot for providing a good number of app lock apps!
    Keep sharing
    Have a great week ahead
    Best Regards
