Application Locker

Tablets and phones are meant to be personal devices.

Tablets and phones are meant to be personal devices but they rarely stay that way. They get handed around to show off photos, to watch videos, or to play games. With AppLock (free), you can take a little of stress out of parting with your Android by keeping certain apps locked up and others freely accessible. It should be a slam dunk, but this app is held up by some odd quirks.
