You then get a link to the question for your audience, a link to the results, a link to the administration of your poll, and a QR code. The QR code is nice and big in order to display on a screen for even those in the back of the room to scan. When your audience enters their response the results are just about instantaneous and best of all, the developers have said the service is most likely always going to be free.
There is even an FAQ page specifically for educators and some of the features include:
- displays the correct answer after student submits his/her answer
- hides answer while polling, so students are not distracted by others' responses
- requests to make the service better
