Zoom breakout timer for teachers
CrowdTimer for teachers
Small-group work that starts and ends on time
Breakout discussions and group tasks eat class time when every group runs on its own clock. CrowdTimer puts the same countdown in front of each group, so a think-pair-share or a problem set wraps together and you reclaim the minutes usually lost to herding students back.
Students can ask for a little more time
When a group is close to a breakthrough, a student taps +1 minute instead of waiting silently or rushing. You stay in charge of the lesson: CrowdTimer shows how many extensions remain so the activity stays inside the period.
See which groups have finished
Groups mark their room done when they have completed the task, giving you a live view of progress across the class. You can move on when groups are ready and check in with the ones that need a hand.
Works for students on any device
Students who join class from a phone browser can still follow the same timer — they enter a name, choose their group, and see the same countdown, so no one is left out of the activity.
Frequently asked questions
Do students need to install anything?
No. Students open CrowdTimer inside the Zoom class, and anyone on a phone browser just opens a link. Only you, as host, add CrowdTimer once from the Zoom Marketplace.
Does CrowdTimer see student names, audio, or video?
CrowdTimer does not access meeting audio, video, or chat. It uses only the limited meeting and timer data needed to run shared countdowns, and meeting-scoped data is purged within about 24 hours.
Can I keep a group from running over the activity time?
Yes. Students can request +1 minute, but you see how many extensions remain, so group work stays inside the lesson plan.
What if a student joins from their phone?
They scan a QR code, enter a name, choose their breakout group, and follow the same shared timer from the browser — no app required.
