About ClassroomTimers
ClassroomTimers is a free set of browser-based timing tools built for teaching, presenting, and focused learning.
Who we are
We are a small independent team focused on practical classroom productivity tools. We believe simple, well-designed timers and clocks can make everyday teaching clearer without requiring accounts, installs, or complicated setup.
Our story
ClassroomTimers started with a straightforward need: teachers often want a large, reliable countdown on a projector or spare screen within seconds—without fighting ads, tiny digits, or app downloads.
From that classroom timer core we added a world clock for cross-time-zone classes, flip and digital clocks for shared time displays, and a stopwatch for drills and practice—keeping the same calm, readable visual language across tools.
Key features
- Classroom Timer: large countdown presets, clear finish warning, and projector-friendly display
- Fullscreen mode: hide chrome so time stays dominant on classroom screens and TVs
- Keep screen awake: optional wake lock for long lessons and always-on displays
- World Clock: compare cities with map context, offsets, and day-night cues
- Flip Clock & Digital Clock: styles, backgrounds, seconds, and date options for desks and boards
- Stopwatch: lap timing with adjustable precision for drills and study tracking
- No account required: preferences stay in your browser; classroom labels are not uploaded
- Works on desktop, tablet, and phone with the same core tools
Our tools
- Classroom Timer — free online countdown for lessons, activities, and exams
- World Clock — fullscreen multi-city times with a live day-night map
- Flip Clock — mechanical-style flip display for shared screens
- Digital Clock — high-contrast digital time with styles and backgrounds
- Stopwatch — online stopwatch with laps for classroom and study use
Future plans
We plan to keep expanding ClassroomTimers for real classrooms. Upcoming directions include:
- More background options for clocks and timer stages
- Dynamic backgrounds that stay calm enough for teaching screens
- More languages beyond English and Simplified Chinese
- Classroom whiteboard tools that work alongside timers and clocks
- Other teaching workflows shaped by teacher feedback
If a feature would help your classroom, we want to hear it. Feedback shapes what we build next.
