# Visualizing the tesseract

Have you ever had problem visualizing the fourth dimension? I have found this app - The Fourth Dimensional App - which helps you visualize the tesseract. (A tesseract is the four dimensional analog of a cube.)

The Fourth Dimension is a 30-page interactive book that explains a single mathematical idea in language that anyone can understand.

Instead of static images or canned videos, this app employs a unique 3D touch interface that lets you literally grasp the concept of the fourth dimension with your own hands.

This amazing app is free for a limited time. Download it now! Visit http://fourthdimensionapp.com

Note: It is only available for iOS devices.

If you search this app on Google, it shows \$2.99 in the search result, but if you open it in the App Store or on the iTunes website, you will see it is free (as of 5pm IST 28 Feb 2015).
