Silent Brainstorm Timer

Runs a silent idea-writing sprint, then a per-person share round built from your participant list, then a dot-vote reminder. A tap counter tallies ideas live and phase chimes mark every handoff. Works offline.

How to play

  1. List participants for the share round, one name per line, and set minutes for silent writing, each person's share turn, and the dot-vote reminder.
  2. Tap Start Brainstorm. The room goes silent first for solo idea-writing, tracked by a live counter with a plus-one button for tallying ideas as they come.
  3. The tool automatically moves into a share round with one timed turn per participant, in the order you listed them, chiming at each handoff.
  4. A final dot-vote reminder phase prompts the group to place their votes, and the session ends with your total idea count on screen.

List your participants, set minutes for silent writing, per-person sharing, and the dot-vote reminder, then tap Start Brainstorm. The room goes silent first while everyone writes ideas alone with no discussion, then the tool moves automatically into a share round with one timed turn for every name on your list in order, and finally into a dot-vote reminder phase to prompt the group toward picking favorites. A soft chime marks every phase change so nobody has to watch a clock. A live idea counter sits on screen the whole time with a simple plus-one button — tap it as fast as ideas land, since every single tap is counted with nothing held back or ignored. Pausing at any point keeps your exact phase and remaining time intact.

Frequently asked questions

How is this different from the Think-Pair-Share Runner tool?
Think-Pair-Share Runner is a classroom routine of silent thinking, then a single paired discussion phase with partners auto-assigned, then a group share cue — it has no idea tally. This tool is a professional brainstorm: silent writing, then a full share round with one timed turn per named participant in sequence, then a dedicated dot-vote reminder phase, plus a live undebounced idea counter that Think-Pair-Share Runner does not have.
Can I tap the idea counter as fast as I want without losing taps?
Yes. The counter has no rate limit or debounce of any kind — every single tap registers immediately and adds exactly one to the total, so it keeps up even during a rapid burst of ideas.
What happens if I don't list any participants for the share round?
The share round is simply skipped and the session moves straight from silent writing into the dot-vote reminder phase — leaving the participant list empty is not an error, it just means there's no per-person share step to run.
