Some of The Best Educational Apps for Undergraduate and Graduate Students

As a a full time doctoral student, iPad is my number 1 companion. I use it for a wide variety of educational purposes but mainly for reading. I have been experimenting with various apps and the visual below features what I believe are some of the most useful apps university/ college students should definitely try. I arranged these apps into 10 categories and for each of these categories I cited two apps that go with it. I have also included a table below the visual where you will find links to the featured apps.
This visual is also available for free download in PDF format.
