There are numerous apps that are useful for college students. I think the most useful apps are those that allow students to access files in the cloud and edit documents. One such well-known cloud service that supports this time of productivity is Google Drive. Another great app is one that allows you to access e-books. Two such apps are IBooks and Kindle. I purchase as many college books as I can through Kindle so that I have access to my textbooks no matter where I am.
