What is a flip clock?
A flip clock shows the time on split cards that fold down to reveal the next digit. The style comes from electromechanical departure boards once common in stations and airports, where each flap snapped into place with a soft clack. People search for it under many names, including flipclock, flip flop clock, and clock flip, but they all describe the same folding digit motion.
This page is a digital flip clock that recreates that motion in your browser. There is nothing to wind and no motor to wear out. Open the page and the current time appears on large cards with the familiar top and bottom split. If you like the classic station look, try a vintage flip clock skin. If you prefer a cleaner desk display, the standard retro flip clock cards work well in both dark and light themes.
How to use it in 3 steps
Flip Clock AI needs no setup: it reads your device clock and shows the current time the moment the page loads. The whole tour is open, set, and place:
- Open this page on any device with a modern browser. The clock reads your device time zone automatically, so there is no setup and no location permission involved. Leave seconds on for a full six digit display or hide them for a calmer four digit look.
- Open Settings and choose 12 or 24 hour time, then toggle seconds, date, and the AM/PM badge. Digit size follows the screen by default, with fixed sizes from S to XL if you want manual control. Every change saves on the device and applies instantly.
- Keep the clock in a tab, install it as an app, or press F for fullscreen on a second monitor. Use the share button to copy a link that carries your format and size choices to another device. Keyboard shortcuts cover fullscreen, settings, hiding controls, and theme.

Where people use it
Study desk
Students keep the clock in a corner of the screen or on a tablet to mark study blocks. Large digits are readable at a glance without breaking focus, and the optional seconds display makes short drills easy to pace.
Streaming overlay
Streamers place the fullscreen clock on a second display or capture the window as a timer backdrop. Solid dark skins read well on video, and hidden controls leave nothing but digits on screen.
Classroom
Teachers project the clock during timed exercises and exams. The date line confirms the day at a glance, and 24 hour mode matches school timetables in many countries.
Presentations
Speakers use fullscreen mode as a silent timekeeper behind a laptop. The high contrast digits stay legible from the back of a room without distracting the audience.
Second monitor
Office workers park the clock on a vertical monitor or an old laptop as a glanceable time source. Because it runs as a page, it shares the screen with dashboards and chat without extra software.
Use it as a flip clock screensaver
This site is a full screen browser display rather than a system screensaver file, but it fills the same role on a desk or a media PC. Open the clock, press F for fullscreen, and choose a retro skin for the vintage flap look. The animation keeps moving every second, so the screen never looks frozen.
Mac
Open the clock in your browser and press F for fullscreen. While fullscreen is active, modern browsers hold the screen awake automatically, so the panel stays lit during the session. Install the page as an app from the browser menu and keep it in the Dock for one click access. Press Escape to exit fullscreen when you return.
Windows
Open the clock in Edge or Chrome and press F for fullscreen. The screen stays awake automatically while fullscreen is active on recent versions of both browsers. Install the page as an app from the browser menu and pin it to the taskbar. The clock resumes correctly after sleep, so an overnight desk display picks up the right time in the morning.
How it keeps accurate time
The display reads your device clock and redraws every second, aligned to the second boundary. There is no tick counter to drift, so background tabs and brief sleep pauses self correct on the next update. World clock pages use the same device zone database for daylight saving. If the minutes look wrong, check the computer date and time setting first, since the page can only be as accurate as the device.
Privacy: it runs in your browser
There is no account and nothing to sign up for. Theme, format, skins, and session counts live in your browser storage on your own device. A custom background image stays in local or session storage and is never uploaded. Clearing site data resets preferences to defaults. See the privacy policy for details.

Frequently asked questions
What do you call a clock where the numbers flip?
It is called a flip clock. The name comes from the split flaps that fold down to reveal the next digit, the same mechanism used in classic railway and airport departure boards. Flip Clock AI recreates that motion with large digital flip cards in your browser, so you get the retro look without buying a physical clock.
Is there a flip clock with seconds?
Yes, Flip Clock AI includes an optional seconds display. The seconds appear as a third pair of flip cards next to the hours and minutes, folding with the same animation. Open Settings and toggle the Seconds switch to show or hide them. The date line and AM/PM badge can be toggled the same way.
How do I get a retro flip clock screensaver on Mac?
Flip Clock AI is a fullscreen browser display rather than a system screensaver file, and it fills the same role. Open the clock, press F to enter fullscreen, and pick a retro skin such as Retro Wood for the vintage look. Fullscreen automatically keeps the screen awake in supporting browsers. Press Escape to exit when you are done.
How do I install a flip clock on Mac?
You can install Flip Clock AI as an app from your browser. In Chrome or Edge, click the install icon in the address bar or use the browser menu install option. On Safari 17 or newer, use the File menu and Add to Dock. The clock then opens in its own window, with settings saved on that Mac.
How do I add a flip clock to Windows?
Install Flip Clock AI as an app on Windows through your browser. Open the site in Chrome or Edge, click the install icon in the address bar or use the install option in the browser menu, and confirm. The clock gets its own window and Start menu entry, and you can pin the taskbar icon for one click access.
Does the flip clock work on MacBook Air and MacBook Pro?
Yes, Flip Clock AI works on any MacBook Air or MacBook Pro. The clock runs in a modern browser such as Safari, Chrome, or Firefox, so the model does not matter. Digits scale to fit the screen, from the smaller Air display to large external monitors, and fullscreen, seconds, and skins behave exactly the same on both machines.
Can I use the flip clock on a second monitor or TV?
Yes, open Flip Clock AI in the browser on the screen you want and press F. On a second monitor it becomes a glanceable desk clock that shares the screen with dashboards. On a TV, open the site in its browser and pick a solid skin such as Classic Black so the large digits read from across the room.
Does it work on phones and tablets?
Yes, Flip Clock AI runs in mobile browsers such as Chrome and Safari on phones and tablets. Digits scale to fit the display, and fullscreen grows them to full size for bedside or desk use. The settings open the same way with a tap, and you can install the site as an app to keep it one tap away.
Can I keep the clock open in a browser tab?
Yes, you can leave the clock open in a tab all day. The time updates every second from your device clock, and the tab title stays in sync on the timer and stopwatch pages. If the computer sleeps, Flip Clock AI resumes correctly when it wakes. For a cleaner setup, install the site so it lives in its own window.
How do I make the flip clock full screen?
Press the F key or click the Fullscreen button under the digits on any Flip Clock AI page. The clock fills the screen and the browser interface fades, which suits presentations, classrooms, and desk displays. Press Escape or move the mouse to bring the controls back and exit. Your format and skin settings stay exactly as you left them.
How do I stop my screen from turning off?
While Flip Clock AI runs fullscreen it automatically holds a screen wake lock in supporting browsers, so the display stays on with no separate toggle. For non fullscreen sessions, extend the display sleep timer in your device settings and keep the device plugged in for all day use. Low power modes and closed lids can still pause the display.
Can I change the size of the digits?
Yes, open Settings and pick a digit size. Auto fit chooses the largest size that fits your display, and fixed sizes S, M, L, and XL override it for a consistent look. Set a smaller fixed size to snap the flip clock beside other apps, or switch back to auto fit before going fullscreen. Your choice saves on the device.
Can I install the flip clock as an app?
Yes, Flip Clock AI is an installable web app with no download. In Chrome or Edge, click the install icon in the address bar, and on Safari 17 or newer use the File menu and Add to Dock. It then runs in its own window without tabs, keeps your settings on that device, and works offline after the first visit.
Is this the same as a Twemco flip clock, and where can I buy one?
No, Flip Clock AI is an independent online clock and is not affiliated with any physical clock maker. If you want a physical flip clock for your desk or wall, check the official website of the maker or its authorized retailers. This site is the free browser alternative, with no purchase, shipping, or maintenance involved.
When was the flip clock invented?
Flip Clock AI is a modern remake, but the flip clock itself became popular in the mid-20th century, when electromechanical split flap displays appeared in stations, airports, and hotel lobbies. Several designers refined the mechanism over the years, so the exact inventor depends on which design you mean. The key idea is large folding digits readable from across a room.
Is Flip Clock AI free, and do I need an account?
Yes, every tool on this site is free and there is no account system. Open the clock, timer, stopwatch, pomodoro, or world clock and use it immediately with no sign up and no email. Your preferences live in your own browser storage, not on our servers, and the tools keep working after you clear site data.
Does it work offline?
Yes, Flip Clock AI keeps working offline after your first visit. A service worker caches the pages, so reopening the site without a connection still shows the clock, timer, stopwatch, and pomodoro tools. The world clock city search prefers fresh zone data, but pinned cities keep working. Visit each page once while online for full coverage.
Does it store my data?
Flip Clock AI stores only your own preferences, and only on your device. Theme, format, skins, and session counts stay in browser local storage, and an optional custom background image stays in local or session storage rather than uploading anywhere. There are no accounts and no tracking cookies in this build. Clearing your browser site data removes these preferences permanently.
Can I switch to 24-hour time?
Yes, open Settings on Flip Clock AI and choose the 24 hour option. Hours then run from 00 to 23 instead of cycling 1 to 12 with an AM/PM badge. The change applies instantly and is saved on the device. World clock cards keep their own format toggle, so you can mix both styles in the same viewing session.
