This app is built around four main themes:

1. First, an ordered list of Presidents is presented which will display the important facts about each person. If you have an internet connection, you can see even more in-depth information about each President by linking directly to his biography on Wikipedia.

2. Second, you are encouraged to memorize the order of the Presidents through a small game. The Presidents are presented in a random list. When you push the "Begin" button, each row gains a set of bars at the right end. If you press and hold the bars for an instant, you can then move each President higher or lower on the list. You can get some feedback by pressing the "Grade" button and then resume moving. It is best to begin either at the top or bottom of the list and then fill it in. If you leave the list and return, you are presented with a whole new random ordered list.

3. Third, there are nearly 500 trivia type questions about the Presidents, their First Ladies, and some of their accomplishments, hobbies, and idiosyncrasies. By pressing the "Next" or "Previous" button a question is presented. After you think you know the answer, press the "Tap to Answer" button and the answer will appear. These questions will appear in a new random order each time you begin.

4. Fourth, in "Who Am I," a collection of portraits and photographs appears. Once you think you know who it is, click on the image – you will see his name as well as a picture of him and his First Lady when they were younger. These pictures will appear in a new random order each time you begin.

The app is targeted at anyone interested in presidential history. It is a universal app and will run on an iPhone (in portrait mode only) or an iPad running (in portrait or landscape mode) IOS version 13 or 14. The background art work is both from WikiCommons as well as the White House website.
