Live Poll Room
Ask a question, share a link, and watch the bars move as votes land.
IntermediateWeb appSocial8–16hAI-buildable 4/5needs backend
A live polling app where results animate in as people vote. The satisfying part is the moment of shared attention — everyone watching the same bars grow. Underneath, it's a good exercise in optimistic updates and in preventing one enthusiastic person from voting fifty times.
