For me it was to scratch the itch of creation. I live for the buzz of creation. There was also a degree of wanting to see how it was to create an app using the latest tools that I don't normally use, I link to a tweet where I suddenly decide to try and make this app, a flash of inspiration that it should be possible. If it had been more difficult, I would have surely given up and the app would not exist. But it was "easy" enough, and here we are. Plus, the original app has been stuck in my brain for a long time and I remembered it fondly. So, there are many factors... but adding things to my resume is not one of them.
