QANDR offers advanced tools to merge results from multiple sessions in the same project. In this way you can create a visualisations that is showing the combined results of all sessions.
This powerful feature can be used on archived sessions, but you can also use it during a live event where several sessions run simultaneously. You can read more about this feature in a case study about two evenings with four break-out rooms each, where in the closing plenary session all the results were merged.
We are working on functionalities for post-session analysis. A beta version of an export function for quantitative data is already available. This contains poll results, rating results and the submitted words and their frequency in a word cloud.
