Biggest Challenge
A constant problem making my app was doing the code because there is so many things you could get wrong that could malfunction your app. Also, it's easy to find what you want to accomplish or update or fix, but hard to actually do it. For example, there's a way you can make your magic feature change sizes too, but it was pretty hard for me to figure out at first. Turns out, it was easy, but it won't always be easy. Sometimes I had duplicate code in my app and didn't find it until i stumbled on the code while checking all of my apps. Coding is really hard sometimes and can give you many errors and failures that can cause you to give up, and that's the real challenge.
