OneFlipClockPomodoro Timer
A focus timer with a clock on its other side. Choose a duration, start it, and get on with your work — flip back to the clock whenever you want to know the time.
25 / 5, or your own split
Start from the classic 25-minute work block and 5-minute break, or set any duration down to the minute.
The clock is one flip away
The same object carries a flip clock on its back. Turn it over to check the time; the session keeps running.
The countdown is in the tab
Switch to another tab and the title tracks the remaining time, so you never have to come back just to look.
Flip Clock for Studying
Study with the timer in front of you instead of reaching for your phone. Start a focus block and flip over to the clock: the remaining time stays in view, with no account and no app to install. If the pomodoro rhythm suits you, the 25 / 5 split starts in one click, and a soft chime marks the end of every block.
Frequently asked questions
- Pick a preset or set your own duration, press start, and work until it chimes. 25 minutes of work with a 5-minute break is the classic version; 50 and 10 works just as well if that suits you.
- Yes. The countdown follows the clock rather than how often the browser lets the page run, so it stays correct even after the tab has been hidden for a long time.
- A soft chime plays at zero and the tab title changes. On desktop and Android you can also get a system notification — your browser asks once, the first time you press start. iPhone browsers cannot show them, so keep the tab open and audible there.
- No. Your setup lives in this browser; there is no sign-up and no profile on a server.
