AppLock

There are plenty of iPhone apps that can hide certain data such as photos and videos behind password protection, but what if you don't want to deal with a brand new third-party app just to view hidden content?

AppLock is a terrific Android utility that can protect a wide range of standard Android apps by requiring users to enter a password before accessing them. This password is in addition to the standard PIN or passcode people might use to secure their Android devices.
