I am very proud to say that my first functioning app is in the iOS App Store! Learning to code an app was a huge undertaking for someone without any official computer science training, but I enjoyed the challenge. Next step is to keep refining/fixing any bugs and transfer the app to Android. After that, I hope to expand the features of the apps to include daily and monthly planners, grade books, etc.
