Based on the technique of asking students to raise one to five fingers, Fist-to-Five is a real-time web app that allows groups to give feedback on questions and offer opinions.
For example, a teacher can ask "How well do you feel you understand JavaScript promises?" or simply make a statement: "The sides of an isoceles triangle have equal length," choose a scale, and allow participants to vote. The teacher can instantly determine whether to review or move on to the next topic.
