That was a pretty great summary of the app, but there is a bit more that you need to know. The app itself is free but it needs Plicker Cards to work, but don’t worry because you can print up to 63 of them for FREE. You can print them out one or two per paper. I chose to print two per page and laminate them. I cut each page in half and had 60 laminated Plicker Cards in under 30 minutes! *Although the website says that laminating the cards may cause glare, and prevent them from scanning, I didn’t have a problem.
