As I was doing the final WeBWorK of the year for my Linear Algebra class, I noticed how sluggish and awkward to use the web interface was from an Android device. The interface was clearly made for a PC, and navigating across problems was a pain.
Inspired, I started to write an Android application, focusing more on the user experience than I usually do in my programs. I picked the Holo Light theme, and organized items in ways following existing apps (GMail, Antenna Pod).
At first I only tested the application on my schools own servers. After recieving complaints from a couple schools, I realize that WeBWorK is considerably fragmented, and each school has its own variation. Although the core app was built in just five days, I spent considerable time providing support and increasing compatibility.
