I have seen iclicker develop from a physical clicker to a software with a mobile app. This software can be used for attendance, surveys and quizzes. I like that it allows individuals to discretely answer questions and have their opinions heard. The nice thing is, they can instantly see results, which helps with quizzes. Registration is quick and easy.

On the spot learning, engagement with others, real time answers.

I liked that iclicker provided instant feedback for professors to gauge how their students were learning material they were lecturing on
