Hand-Raise Queue

Tap a student's name the moment their hand goes up and they lock into a numbered, fair queue. No forgotten kids, no arguing about who was first — just a visible answering order.

How to play

  1. Type or paste your class roster, one name per line, then tap Start Class.
  2. As hands go up, tap each student's name in the roster grid — they're added to the numbered queue in the order tapped.
  3. Work down the queue by tapping Answered (moves them to the answered list) or Skip (removes them without counting an answer).
  4. Tap Clear Queue to reset for the next question while keeping the same roster, or New Roster to start over completely.

Type your class roster once, then hand the screen to the front of the room or project it. The instant a hand goes up, tap that student's name and they lock into a numbered queue in the exact order they raised — no more "I had my hand up first" arguments. Work through the line by marking each student Answered or Skip, and both the queue and the roster update instantly so everyone can see who's next. It's built for fast, repeated tapping during a real discussion, so no raise is ever dropped even when several hands go up at once. Clear the queue between questions while keeping your roster loaded, or start fresh with a new class list anytime.

Frequently asked questions

What happens if two students raise their hands at almost the same time?
Each tap is recorded the instant it happens and appended to the queue in order, so simultaneous or rapid-fire raises are never dropped or merged — everyone gets their own numbered spot.
Can a student accidentally get added to the queue twice?
No. Once a name is in the queue it's dimmed and marked with a checkmark in the roster, and tapping it again does nothing until they're resolved with Answered or Skip.
Does clearing the queue erase my class roster too?
No. Clear Queue only empties the current line of raised hands and the answered list — your roster stays loaded so you can immediately start queuing for the next question.
