A clock that stays out of the way

Flip Clock is a free online flip clock at flipclock.bond. It runs entirely in your browser — no signup, no download, no account.

It started from a simple need: a large, calm, readable clock for a desk, a second monitor, a classroom wall or a focus session. So the clock is the page, not a widget inside a marketing site.

Everything is client-side. Your settings live in localStorage on your device, uploaded photos never leave your browser, and the timer engine measures against the system clock so it stays accurate in background tabs.

How Flip Clock is different

• One shared flip engine on every page — clock, timer, stopwatch, Pomodoro, world and aesthetic views all flip the same way.
• Real tool controls: fullscreen, hide-controls, keep-awake, OLED night mode, tick volume, shareable settings URL.
• Installable PWA with offline support; accurate timers via requestAnimationFrame against Date.now.
• Dark-first design with a real light mode, keyboard shortcuts, and reduced-motion support.
