Early in the iOS days I wrote a car lease/loan payment app. Nothing fancy if you knew how to use a business calculator, but it quickly did all the calculations for lease/loan buying. The UI was so-so, but it worked and I had gotten some feedback it was useful. I had only built it for myself and then released it on the App Store b/c why not. The app ended up referenced in a later interview I had and helped land a job doing mobile development. This was very early days of iOS development, so just navigating the mess of getting an app signed and uploaded was sometimes a challenge.
