Everybody is concerned about his/her privacy. Apple only allows you to password protect your iOS device, but what if you want to protect individual apps like Photos, Facebook or the Messages app? By default iOS does not allow you to password protect specific apps. But once you jailbreak your iOS device there are endless possibilities.
The newly released iAppLock tweak allows you to do what Apple didn’t. Using this tweak you can lock your Photos, Videos, Contacts, Facebook or any app you like. Simply set a passcode and add the apps you want to lock to the lock list, and no one will be able to access your protected apps.
iAppLock places an icon on the homescreen that is a downside of this tweak but of course you can get rid of that by placing it in a folder. The UI of the app has been nicely design that makes it look like an App Store application, which is pretty cool. It also lacks the ability to add password protection to folders, which can easily be done with Lockdown Pro.
iAppLock is available for free at Cydia under BigBoss repo and requires iOS 7. However the free version limits the number of apps that can be locked to five. A Pro Version is under progress and that will get you rid of this limit. Until then you can enjoy the free version.
