Third Party Google Apps

An app I found appealing on Google Drive is Cloud ePub Reader.  I found this appealing because it seemed like a good idea because reading is well liked and enjoyed by everyone.  This seems like it would be a very successful app because people could use it on the go and be used by people of all ages.  Another app I found appealing is Cloud Coloring Book.  This is a very fun app that can be fun for all ages.  It saves paper and money for colors and coloring books.  This is a very entertaining app!
