App Lock – Fingerprint Pin and Pattern – Fingerprint Password – Lock Apps – LOCKit – AppLock Master

App Lock lets you lock individual apps to prevent unauthorized access. Anyone who wants to open Facebook, WhatsApp, photo galleries, SMS messages, emails from your email app, must have your private password, pattern key or fingerprint to unlock the apps.
You often lend your phone to relatives or friends but you are worried because you don’t want others to see some photos, videos, or files. Or maybe there are some applications on your smartphone you want to be more secure and need a private key for those.
