Wooclap is a real-time polling software that allows instructors to engage with their students and gauge their understanding of the material. Students respond to your questions and polls via a web link on their mobile devices, making this an ideal tool for remote and in-person instruction. Some of the activities offered include multiple-choice, find-a-number, polls, word cloud, and open questions. You can access many features for free but a subscription unlocks more features such as exporting results to a PDF. Free/Paid.
