ABCD Cards is an educational app developed by Western Washington University (WWU). It serves as a convenient polling and Q&A tool, replacing the traditional paper ABCD card method. With a simple interface, this app allows students to display their answers to instructors' questions without the need for physical cards.

By clicking on a letter or color, the screen is filled with the selected option, allowing the instructor to easily gauge the students' responses. Clicking again brings the user back to the main screen.

ABCD Cards is designed to be user-friendly and paper-free, making it an eco-friendly choice for educational settings. It offers a practical alternative to the traditional ABCD card method, providing instructors and students with a more efficient way to engage in interactive learning experiences.
