Every phone in the room,
interacting with you live
An interaction tool for corporate trainers, speakers and teachers. Your audience scans a QR code to vote, ask and answer quizzes; as you move through your slides, their phones follow along. No app needed!
Sign in with Google and create your first session in a minute.
One session, one QR code, every interaction
Everything below is a real Ripple screen.
The audience upvotes; cover the hot topics first
List your topics and the audience upvotes the ones they want to hear more about, or suggests their own. The most upvoted rise to the surface. Click one when you've covered it and it sinks back into the sea.


Watch the results grow live
Single or multiple choice, shown as bars, a donut or a word cloud; switch anytime. Or keep results hidden until you reveal them.


Countdown, reveal, leaderboard
Faster correct answers score more. Each question ends with the answer, and the final leaderboard gets the whole room going. Anyone who skips the nickname still gets a fun one.


Right on your slides
Insert Ripple into a slide and send it to the back: reactions, comments and the understanding meter happen behind your content. Your clicker works as usual and phones switch automatically. Works on Windows and Mac.
