Need a speaker? Use ✋ Pick One — turn on 'Exclude picked' so everyone gets a turn. Customize with student names! Teacher tool in 7 languages.
Classroom Timer
See remaining time in a visual circle! Even children who cannot read clocks yet can tell how much time is left at a glance. ⏳ Start activity timers instantly with 1, 3, 5, 10, or 15 minutes—colors darken 10 seconds before the chime rings. ⏱️ Stopwatch measures down to 0.1s with lap records. 🔁 Rotation mode lets you set rounds like '4 mins x 5 turns' with automatic chimes between turns—perfect for group presentations! Great teaching tool, supports 7 languages.
