Visual Timer for Classroom Activities

Research shows that visual timers help students manage their time and reduce anxiety during timed tasks. EventTimer displays a large, easy-to-read countdown that the entire classroom can see on a smartboard, projector, or TV. The color-coded progress. Green for plenty of time, yellow for a heads-up, red for wrapping up, gives students a clear visual cue without the teacher needing to interrupt. Use it for reading time, journal writing, art projects, math sprints, or any timed activity that benefits from a shared visual reference.

• Color-coded time warnings (green → yellow → red)
• Large digits readable from the back of the room
• Works on smartboards, projectors, and TVs
• No app install, runs in any browser

Classroom Clock for Exams & Tests

Give every student a fair, clearly visible countdown during exams and quizzes. Project EventTimer on the classroom screen so students can pace themselves without constantly asking "how much time is left?" The fullscreen mode removes all distractions, showing only the remaining time. Set preset durations for common test lengths like 10 minutes for a quiz, 30 minutes for a mid-term, 60 minutes for a final, and save them as bookmarks for instant reuse throughout the year.

• Fullscreen exam countdown
• Preset durations for quick setup
• Silent mode. No sounds to disturb test-takers
• Bookmark presets for reuse

Transition Timer & Group Work Timer

Smooth transitions save precious classroom minutes. Set a 2-minute transition timer between activities so students know exactly how long they have to pack up, move seats, or get materials ready. For group work, assign a 10- or 15-minute timer so every group stays focused and finishes on time. The timer's flexible duration input lets you type any number of minutes and seconds, so you're never locked into preset increments. Teachers who use visual timers for transitions report saving up to 15 minutes of instructional time per day.

• Any custom duration, seconds to hours
• Quick-start presets (2 min, 5 min, 10 min)
• Count-up mode to track elapsed time
• Shareable link for hybrid/remote classrooms
