Want to take a picture, but you don't want it on your main camera roll? Other Roll solves your problem. Other roll saves its pictures in its own folder, where PhotoStream, iPhoto, and your standard camera roll can't access it. Only Other Roll has access to your Other Roll photos.

Have pictures you want to keep but don't want your kids or nosy colleagues looking at? Other Roll is PIN protected, so even if someone has your phone and launches Other Roll they can't see your other roll without your PIN.

Note: Other Roll does not encrypt your photos. It stores them in a sandbox-protected folder that other applications do not have access to. With physical access to your phone or backups, a security expert could conceivably pull these pictures off of your phone. Other Roll should not be used for illegal purposes.
