Plickers lets you poll your class for free, without the need for student devices. Just give each student a card (a “paper clicker”), and use your iPhone/iPad to scan them to do instant checks-for-understanding, exit tickets, and impromptu polls. Best of all, your data is automatically saved, student-by-student, at plickers.com.

With the free version of Plickers, you can: 

• Add up to 5 Questions to each Set (you can make as many Sets or individual Questions as you’d like)
• Enter answer choices for Graded mode, True/False mode, or mark a Question as a Survey (with no correct answer choices) 
• Rearrange the order of Questions in a Set
• Edit the layout 
• Upload images 
• Duplicate Questions 

With Plickers Pro, you can access additional features to help you create high-quality content: 

• Add images quickly, using Plickers’ built-in image search
• Add an unlimited number of Questions to each Set
