Online Digital Flip Clock

OneFlipClock is a full-screen flipclock for your desk, tablet or second monitor. Flip it over and it becomes a focus timer — nothing to install, nothing to sign up for.

• Built to be left on

  Full screen and ad-free. After three seconds of stillness every control and the cursor fade away, and the screen is kept awake.

• Two sides, one object

  A clock on one side, a pomodoro timer on the other, joined by a single flipping motion — no second page, no second app.

• Nothing to install

  It runs in the browser and remembers your theme, mode and last duration locally. Available in 13 languages.

Frequently asked questions

How do I use it as a screensaver?＋

Go full screen and leave it. Controls and the cursor hide after three seconds of no input, and return as soon as you move the mouse.

Will the clock burn into my screen?＋

The numerals drift a few pixels on a slow cycle to spread the wear, and the screen is kept from sleeping. On an OLED panel we still suggest lowering brightness for very long sessions.

Do I need an account?＋

No. Your preferences are stored in this browser only — there is no sign-up and no server-side profile, so clearing site data resets them.

Does it work on a phone or tablet?＋

Yes. The layout adapts to any screen size, and the switch that flips between clock and focus stays within reach.

Are there keyboard shortcuts?＋

Space starts or pauses a timer, F toggles full screen, and T flips between the clock and the focus timer. They are ignored while you type in a field.

Can I see other time zones?＋

Yes — the world clock has its own page: add any city and each card shows its current local time. Your cities are kept for your next visit.
