10+ Best App Lockers in Google Play Store

Android is an operating system developed by Google and Open Hand Alliance written in Java (UI) and C++ programming language. The model of operation is open source meaning its source code is made available with a license in which the copyright holder provides the rights to study, change and distribute the software to anyone and for any purpose.

Its marketing target is smartphones, tablets, computers and other android utilities such as Android TV and Android Wear such as Android smart watch.

It offers lots of exclusive features that are user friendly thereby making it the more popular with a large variety of people compared to other operating systems in this space such as iOS and Windows. Some of the features include:

However cool or cheap android phones are, they are losing when it comes to security and protection of user privacy. This gives an upper edge to other operating systems such as iOS over it thus driving the large market of people who value security and privacy away from it.

Even though android has in built security options such as capability to add passcodes to lock the screen, fingerprint password to unlock the phone and built-in encryption; these are but basic and nowhere near to being complex or matching other more advanced ones in the market.

Security and privacy is one of the many aspects people look for while buying a phone. One checks whether it has passcodes and the variety of styles of the passcode. Many people also like to feel secure when they hand their phone to other people thus bringing in the issue of ability of the phone to lock several apps that they feel have more sensitive and private information. Many of the sensitive apps that people love to keep private is Messaging, WhatsApp and Gallery.

Here is a list of the 10 Best App Lockers operational in android that will enable you to pick the one most suitable to your needs:
