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
Step 1: open the clock
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.
Step 2: set the format
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.
Step 3: place it on screen
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.
Features
Seconds, 12/24h, and date
The flip clock with seconds shows hours, minutes, and seconds as three folding pairs. Switch between 12 hour time with an AM/PM badge and 24 hour time from 00 to 23. A date line under the digits shows the weekday and month, and each element can be toggled on its own so the display fits the room.
Skins
Eight skins restyle the cards, digit font, corner radius, and background in one tap. Choices range from classic black and paper cream to neon, glass, mono, and terminal. Open the aesthetic flip clock gallery to preview each style on a live clock, then pick an accent color and an optional background to finish the look.
Fullscreen and keep awake
Fullscreen fills the display and hides browser chrome, which suits classrooms, presentations, and streaming overlays. The keep awake option asks the browser to hold a screen wake lock while the clock is visible. For all day use, also set a longer display sleep delay on the computer and keep the device plugged in.
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, enter fullscreen, and turn on the keep awake option. Adjust the display sleep setting to a longer delay 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. Turn on keep awake and set the display sleep delay longer for the session. 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.

FAQ
What do you call a clock where the numbers flip?
It is called a flip clock, sometimes written as flipclock or clock flip. 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. Our online version recreates that motion with large digital flip cards in your browser, so you get the retro look without buying a physical clock. You can switch skins anytime on the aesthetic page.
Is there a flip clock with seconds?
Yes, this flip clock includes an optional seconds display. The seconds appear as a third pair of flip cards next to hours and minutes, and each card folds with the same animation as the rest of the clock. Open Settings and turn the Seconds switch on or off to match your preference. The date and AM/PM badge can be toggled the same way, so the display stays as simple or as detailed as you like.
How do I get a retro flip clock screensaver on Mac?
This site is a full screen browser display, not a system screensaver, but it works well in the same role. Open the clock, press F to enter fullscreen, and pick a retro skin such as Retro Wood on the aesthetic page for the vintage look. If you want the display to stay visible, turn on the keep awake option and set your Mac display sleep to a longer delay. Press Escape to exit when you are done.

Does the flip clock work on MacBook Air and MacBook Pro?
Yes, it works on both MacBook Air and MacBook Pro. The clock runs in any modern browser such as Safari, Chrome, or Firefox, so the specific MacBook model does not matter. Digits scale to fit the screen, from the smaller Air display to larger external monitors. Fullscreen mode and the optional seconds display work the same way on both machines.
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 using your device clock, and the tab title stays in sync on timer and stopwatch pages. For a cleaner desk setup, install the site as an app so it lives in its own window instead of a tab. If your computer sleeps, the clock resumes correctly when it wakes.
How do I make the flip clock full screen?
Press the F key or click the Fullscreen button under the digits. The clock fills the entire screen and the browser interface hides away, which suits presentations, classrooms, and desk displays.

How do I stop my screen from turning off?
Use the keep awake option on the clock page to ask the browser to hold a screen wake lock while the clock is visible. This works in supporting browsers on desktop and mobile. For longer sessions, also adjust your computer display sleep setting to a longer delay. Note that low power modes and closed lids can still pause the display, so keep the device plugged in for all day use.
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 you have in mind or one of its authorized retailers. This site is the free browser alternative: it recreates the flipping digits on any screen with no purchase, shipping, or maintenance.
When was the flip clock invented?
Flip clocks became popular in the mid-20th century, when electromechanical split flap displays started appearing in public places such as stations and airports. The exact inventor depends on which mechanism you mean, since several designers refined the flap idea over the years. What matters for this site is the look: large folding digits that remain 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. If you clear site data, settings return to defaults, but the tools keep working.
Does it work offline?
Yes, after your first visit the clock shell loads offline. The pages are cached by a service worker, so reopening the site without a connection still shows the clock, timer, stopwatch, and pomodoro tools. The world clock city search needs fresh zone data on first use, but pinned cities keep working. For best results, visit each page once while online.
Does it store my data?
Your settings stay on your own device and are never sent to our servers. Theme, format, skins, and session counts live in browser local storage, and an optional custom background image stays in local or session storage. 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 and choose the 24 hour option. Hours then run from 00 to 23 instead of repeating 1 to 12 with an AM/PM badge. The change applies instantly to the main display and is saved on the device. World clock cards keep their own format toggle, so you can mix a 24 hour main clock with 12 hour city cards if you prefer.
