September 2018 upgrade
Well I have been using Plickers for some time. The use of cards to collect answers from student is great. However with the recent upgrade this app is no longer useable for me as all my questions that I put in are unusable because of the change they made in Live view. From what I can see they limited the number of characters for the questions so my questions are not complete anymore as they do not show fully. They advertise that you have choice of layout in their pro version. I tried it but still getting the same problem. I wrote them an email as soon as I was aware of the problem and still waiting for a reply. Too bad it WAS such a good app.
