Question Queuer is a question queueing tool for use in classrooms.
Sometimes there are just too many students asking the teacher questions or for help, forming a "queue" that is hard to keep track mentally.
With Question Queuer, students can connect to a teacher via MultipeerConnectivity, and join the queue with the press of a button on their devices. The teacher has full control over the queue, being able to add, remove, and reorder students!
