The inspiration for Squid started when Andrew Hughes was a Computer Engineering student at Cal Poly in San Luis Obispo. He wanted to take digital handwritten notes in classes so he wasn’t limited by paper or notebook size, so he could save, backup, and share his notes, and so he could carry all his notes with him on a single device. Unfortunately, the technology of the day wasn’t up to the task. Tablet PCs left a lot to be desired.

Then came Android. Andrew enrolled in the first Android course offered at Cal Poly by David Janzen in January 2010. Andrew carried his ideas forward in his Master’s thesis where he added active pen support to Android.
