It has happened that you will pass your phone to someone to see a photo and still see the other ?
Yes? So this application is to prevent such undesirable times when someone sees a picture you do not want anyone to see.
It provides a simple and intuitive interface where you select the photos you want others to see and can only see that person or those photos and sounds an alarm if they try to go beyond what you owe.
