I was at the MIT-Vienna-Conference and they had a pretty nice App-System (Superevent), where Questions to the Speaker could be asked per the Superevent-app, upvoted from others and finally answered by the speaker, all without hand-raising, etc.

I now would like to try to implement that sort of "Guerilla" in my University for Lectures, since the Professors will never agree to use something like this in the near future. Therefore i also don´t have the money to buy a Conference App. Most of them are restricted to 25-75 people in the free plan, but we normally have 150-200 people sitting in a lecture.

So here´s my question: Does anybody know of free solutions of this?

My primal need is: Question to speaker-App for Android and iOS

My wish would be: An own "Help-area" for each lecture, possibility to provide resource-links, up and downvote(Evaluation) of lecture.

I could get my hand around some money by asking the student committee, but most of the conference apps work on a plan per conference, which would be way to expensive for all the lectures in my study.

    May I ask why?

    Perhaps this system might work well at a conference. But I do not think it would translate well to a normal lecture class (as I assume the OP is talking about). Distracting students en mass by encouraging them to faff about with smartphones, whilst the lecturer carries on talking, sounds like a terrible idea. If it's really interesting or important, you may interrupt the lecture. Otherwise, save it until the end.

    i understand what you mean, but that´s actually not the point. In my studies even if students have questions they don´t want to ask them in front of everybody or forget them until the end and for sure not ask something that would start a discussion. They are shy. It´s an austrian thing maybe. Let´s just say, the normal "Are there any questions?" at the end doesn´t work. That´s why it would be nice to have a system, where you can ask questions anonymously. The answering should for sure happen at the end. I was very surprised at the conference how good it worked.

  • I use TodaysMeet. It's a tweeter-like forum for students to ask questions and I usually follow up online during break or after the lecture. You don't need a Tweeter account to operate it. I do not like having a rating function with your suggested service. The high/low rating can be so conflated and I am not sure about its usefulness. Mar 27, 2015 at 19:58

This free guide - the Event App Bible - lists lots of conference/event apps. I believe there are a mixture of free and paid-for systems included. You should look at the "Audience Response Systems" to id apps that offer this type of functionality, and cross reference that against the pricing table. Hopefully you can find something that works for you. (The guide comes from the Event Manager Blog and was updated recently (2015))


If you don't find a proper open source implementation, you could use Twitter with retweet counts as upvotes and hashtags for each course. I've seen it used by conferences as a question suggestion mechanism.

  • Problem is, that the people need a twitter account, which is not very common in austria

    @mordondro: True, but signing up for an anonymous twitter account isn't any harder than installing a special-purpose app and setting it up for your courses. (They are both easy but take a minute or two and some instructions.) Mar 27, 2015 at 20:33
