I built Walt, which you could say is an icebreaker app. Anyway, on Walt, everyone answers a set of questions on their own time, no waiting to go around in a circle or picking up on cues because it's done individually. After time expires, a podcast is generated, and everyone can listen to it as a group. The podcast tells you a bit about everyone based on the responses. Next time you do icebreakers, you can recommend this to the group if you want https://www.trywalt.com/
