For a long time now I have been looking for a tool that enables instant polling in the classroom or in the lecture room. I specifically wanted something that; doesn't require registration (especially from the people I'm polling), updates very quickly, works on any platform from computers to mobile devices
It looks like I have finally found what I've been looking for and best of all it's free. The tool that I have found is Mentimeter and it does all of the above.
