Presidents / USA 4.0

This app is centered around four main themes:

1. An ordered list of Presidents is presented, providing essential facts about each individual. With an internet connection, users can access more detailed information about each President by directly linking to their Wikipedia biography.

2. Users are encouraged to memorize the order of the Presidents through a challenging game. Presidents are displayed in a random order. By interacting with the "Begin" button, a dynamic interface allows users to adjust the position of each President on the list. Immediate feedback is available by using the "Grade" button, enhancing the learning experience. Additionally, starting at either end of the list and gradually filling it out is recommended. Upon returning to the game, users are greeted with a fresh random list.

3. Explore almost 500 trivia questions related to the Presidents, their First Ladies, accomplishments, hobbies, and unique traits. Users can navigate through questions by utilizing the "Next" or "Previous" buttons. After formulating an answer, users reveal it by tapping on the "Tap to Answer" button. Questions are rearranged in a new random sequence with each session.

4. Engage in a guessing game with a collection of portrait photographs. Users can guess the identity portrayed in each image and then reveal their name along with a picture of them and their First Lady during their younger years. The images are presented in a different random order each time users begin the challenge.

This app caters to individuals interested in presidential history. It functions as a universal app compatible with both iPhone (in portrait mode) and iPad (in portrait or landscape mode) devices running iOS versions 13 or 14.
