The ToolWizAppLock
Setting up a security is necessary for your device privacy and your files, account and even your life's safety. Such compromise might be dangerous enough to anyone or the files itself to be hacked.
In this app, you can secure your downloaded or bloatware apps and even incrypts data such as Images, Video, Audio and any other files from a physical intruder.
Here, you can see the choices of apps you can lock and the vault of incrypted files.
Which is pretty convenient.
Suggestion
For added security detail, my suggestion is to have the pattern itself be invisible. Because the security itself is obvious.
It's importance is that if it is visible it can be easily track by an intruder. By making it invisible chances of the bad guys acquiring your pattern password will be minimal. It also prevents memorization of other people who would open your smart phone.
My other suggestion is to include a pin lock (which composed of several desired number) , a voice recognition and a thumbmark password. By which the user of this app can choose what security features that suits them most.
That's all. . .
