What is it? is an audience interaction platform that allows you to host real-time online conversations as you present, as well as deliver quick polls/surveys. It is an easy to use audience participation tool that enables you to pose questions to your audience that they can answer using their mobile devices. Alternativey, your audience can use to ask you questions or contibute ideas during the presentation.

What can it do?

A free account enables you to:

  • Create polls or surveys in advance to ask your audience during a presentation
  • Make live polls on the fly to receive instant feedback
  • Collect and curate ideas from your audience
  • Display poll results and questions onscreen to the audience
  • View and export analytics for your event

It allows your audience to:

  • Ask questions from any device connected to the internet
  • Upvote the questions they like the most
  • Contribute ideas to the presenter

The free version offers presenters the opportunity for interaction with up to 1000 participants. Questions are anonymous and the audience can upvote (like) each other’s questions, allowing you to see the key questions during the Q&A period.

A paid account offers more features, including the ability to embed in a presentation and to share documents (.pdf and .ppt) with your audience in real-time. It also allows you to monitor and check questions before you display them to your audience.

Download the App

Note: The App is free to download for Android and iOS. However, is a web service so the mobile website works very well and I would recommend it for one time users.

Tips for getting the most out of

Using in teaching and learning can be used in both small and large group teaching sessions. It is especially useful in large lecture theatres, where it may be difficult to hear students’ questions clearly or where students are reticent to ask a question in front of their peers. See Alistair Cohen’s light-hearted review of the App here:

Teaching scenarios where can be used:

Ice-breakers – start your class with a warm-up question to encourage interaction from your students from the very beginning of the lecture.

Check for understanding – make sure that your students are keeping up with the lesson and your points are getting through to them by asking quiz questions at intervals throughout your lecture.

Crowd-source ideas – generate ideas for research projects or approaches to solving a research question or simply use this feature to kick-start discussion about a topic.

Groupwork and collaboration – rather than vote individually, ask your students to form small groups to discuss a problem or statement in more depth. Explain that they will use to report back the prevailing view of the group. The call to vote from the lecturer should help groups to arrive at a collective decision. This is an effective technique to encourage discussion even when it would be possible for everyone to vote individually. It is also particularly useful when not every student has a suitable device to access
