App Inventor is a program design to make different kinds of apps. I used this program to make this app, which is a small test on United States History, as shown below. The making of the apps was a hard process that requires time and patients in order to make the app function properly and make it look like how when you envisioned it. Some of the challenges I faced with this program was misspelling a word and placing things in the wrong place, these mistakes are the ones that can cause your app not to function properly or change the appearance of the app.
