Artkive

Have you heard of this app?  If you have children and you think each thing that they make is precious but seriously your refrigerator is only so big...you should get this app.  The app allows you to take a picture of each piece of art and date it as well as add any notes you would like.  You have the option of sharing your artkive with others and also of making a book of the pictures of their artwork.  If you have more than one child making art it allows you to have separate artkives for each child. 

What apps do you have that I need to know about?
