AppLock
AppLock allows you to set passwords or unlock patterns for specific apps or areas of your smartphone, which is great if you don't want to lock your home screen but want to keep specific data safe.You will find a list of all the apps on the device in the AppLock main menu. Here you can decide which apps should be password protected and which should not.
AppLock is extremely quick and easy to set up, and you will
be able to restrict access to important items in no time at all. There
are also many customization options, such as the ability to lock off
certain phone features like accepting calls or accessing the settings.
Some of the advanced features are reserved for the premium (paid)
version of the app.Andrognito
This app is not only useful, but also pretty, thanks to its modern, flat design. Andrognito password protects your content and does it in a stealthy manner.Andrognito itself is secured by a four-digit PIN, with files being bound in three layers of encryption. You can use it to hide pictures, documents, videos, apps and more; data hidden by Andrognito will never appear in the recent apps list.
The Andrognito app itself does appear in the app drawer, but
you can change this by activating stealth mode in the app settings. Once
stealth mode is activated, you will only be able to open the app
by entering your PIN on the dial of the phone app and pressing call.Smart Hide Calculator
While the aforementioned apps will either encrypt or hide data, Smart Hide Calculator takes security a step further. When you open the app, Smart Hide Calculator masquerades as an unobtrusive, fully functional... yes, you guessed it, calculator.Upon first opening the app you will be asked to enter a number on the calculator screen: this will then act as your password. To access your data after this point, all you will need to do is type in that number and press the equals button.
