Ink is a mobile notebook application. The goal of Ink is to make categorizing and taking notes as simple as possible. I wanted a way to quickly add new notes and organize them in the simplest way possible. Many Android notebook apps at the time treated notes like pure information. On the contrary, I wanted to treat notes like they are physical papers. I wanted a singular "home" button that made me clear where to look at when I want to see all of them. I wanted to swipe the screen as if I am physically swiping through a pile of notes. I wanted a singular way of organizing my notes so that I know exactly where to go to find them. In other words, I wanted to be spatially aware of my notes. I made Ink to do just that.
