Android: If you don't have a problem letting your buddy browse the web on your Android device but you don't want him reading your email or messing with the settings, Android Protector password protects individual applications without locking down the whole phone.
There's a myriad of reasons you might want to only lock down part of your Android device: you want to let a friend use it without them getting into your personal stuff, your kid wants to play games but you don't want them screwing up the settings, or you want to make sure nobody knows your comic book reader is filled with Sailor Moon manga.
Android Protector is a lightweight Android application that secures applications on a user-defined list with a simple PIN code. Install the app, run it and set your PIN, and then flag the applications you want to secure. You can toggle Android Protection on and off from the notification bar — having it on all the time would be an enormous pain — so your apps are only locked down when you need them to be.
The free version of Android Protector allows you to lock down up to 10 applications — more than enough for things like Settings, Messaging, Gmail and the like. You can purchase the premium version for $1.02 and enjoy unlimited application locking.
