A minimalist, browser-based clock designed for exams, interviews, and presentations.
Responsive Exam Clock is a single-file web utility built to display the current time clearly and elegantly on any screen.
Unlike standard system clocks, this tool is optimized for projection and distance reading. It features a Swiss-style analog face paired with a tabular-numeral digital display, ensuring readability whether displayed on a 100-inch projector screen or a 13-inch laptop.
- 🇨🇭 Swiss Design: A clean, distraction-free interface inspired by classic Swiss railway clocks.
- 🌗 Dark & Light Themes: One-click toggle to switch between themes, perfect for dim exam rooms or bright classrooms.
- 📱 True Responsiveness: The canvas redraws itself on window resize, ensuring crisp graphics on Retina/4K displays and correct proportions on any device.
- ⚡ Double-Click Fullscreen: simple gesture control to maximize the display and hide browser UI.
- 🌐 Bilingual Interface: Built-in support for English and Chinese (switchable via UI).
- 🚀 Zero Dependencies: Built with pure Vanilla JS, HTML5 Canvas, and CSS3. No frameworks, no installation required.
