When I open the Photo App, the album "Camera Roll" contains all the pictures stored on my iPhone, which might include the pictures I took with the camera or I saved from websites. I created another album, say "vacation" that contains some of the pictures but these pictures still show up in "Camera Roll". My goal is to find an app that after you create a new album to store some of the pictures, the same pictures will get deleted from the main "Camera Roll". Therefore, there are no duplicated pictures stored on the iPhone. Please advise if you guys know such apps. Thanks in advance.
