I developed this app in about 2 hours. I found the most interesting part was how easy it was to add more colors. I also found it interesting that there are so many variables as options to customize the app. I found the most difficult part was making sure all the variables were added/connected correctly. I customized this app in several ways. I chose a different background, I added two more colors, and the line size is the same as the dot size. I also added the shake to clear option and changed the button from “wipe” to “clear”. I plan to try to figure out how to add a slider so that the size of the line can have more options than the two mine have. This app was definitely more challenging than HelloPurr, but I still enjoyed it.
