A timer cube for the tab you already have open.
TimerFlip is a free countdown timer shaped like a timer cube. It is meant to feel as direct as the physical one: choose a face, start working, come back when the time is up. The same clock also runs a Pomodoro cycle, a classroom timer, a stopwatch and interval workouts.
A timer cube puts a few durations on one object. You pick a face and start the countdown. TimerFlip is that object in the browser: a virtual timer cube for study, work, and short focus blocks. Nothing to install, and no account to create.
Use it as a study timer, a focus timer with an alarm, or a plain free online timer when you already have a tab open.
Students, people blocking time at work, teachers running a lesson from the projector, event hosts keeping speakers to time, coaches and anyone doing HIIT at home, parents who want a simple visual countdown, and anyone who needs a timer without another account. The page is the product. There is no login and no backend.
Choose 5, 10, 15, 20, 30, or 60 minutes. The cube turns to that face, and the countdown begins when you press Start. Pause and resume when you need to, or reset to the full duration. For any other length, enter minutes and seconds up to 24 hours.
The countdown is calculated from timestamps, not from a chain of one-second delays. Switch tabs, or leave the phone locked, and the time left is still right when you come back. The stopwatch works the same way, and interval beeps are queued ahead on the audio clock. Your sound and view choices, Pomodoro lengths and last interval plan stay on this device.
The same clock, set up for five other jobs. Each one has its own page.
Twenty-five minute focus blocks with breaks that start by themselves, and a long break after every fourth. The cube shows the next block on its side face.
Opens in the digital view with a thick bar that slides from green to red. One button puts it on the board for the whole room.
Digits that turn amber, then red, and keep counting past zero, so a speaker and the host both see how far over a talk has run. The host can send short notes to the stage screen too.
Counts up in hundredths, with lap times, the fastest and slowest marked, and a button that copies the lot into a spreadsheet.
Work and rest rounds for HIIT and Tabata, with a 3-2-1 beep before every switch and colours you can read mid-burpee.
Six faces, six kinds of work. Pick the one that matches the task.
A short burst. Review a few flashcards, clear a desk, or start the task you have been putting off. Five minutes is small enough that starting is the whole point.
A compact block of reading, practice, or inbox clearing before a longer session. Useful for warm-ups and for younger students who do better with a visible finish.
A quarter hour. Long enough to draft something or finish a short lesson, short enough to see the end from the start. This is the time on the top face.
A focused block for practice, email, or a meeting prep. Twenty minutes sits between a warm-up and a full half hour.
A standard focus block, five minutes longer than a Pomodoro, with a little time left afterward to stand up. This is the face the cube shows when you first open the page.
A deep-work hour for writing, revision, or a class activity. The display switches to hours only when a custom timer runs past 99 minutes.
Leave the alarm on for a short chime at zero, or turn it off for a silent finish. Stop the sound without resetting the clock. Browsers sometimes block audio until you have clicked or typed on the page. If that happens, the cube still says Time's up, and a tap plays the chime.
Full screen shows only the countdown, as large as the screen allows. A slim bar along the bottom keeps the presets, pause, reset, sound, and the Cube or Digital view within reach, and fades away while the timer runs. Move the mouse or tap to bring it back, and press Escape to leave. On a phone, full screen turns sideways.
On a computer, a small floating timer stays on top of your other apps, so the clock is visible while you work somewhere else. Closing it leaves the timer running on the page. On the stopwatch it keeps the hundredths.
Put the clock alone on a projector or TV while the buttons stay on your laptop. Press Second screen, drag the new window onto the big display and click it to fill that screen. Every tool has it, so a lesson, a race or a workout can run on the wall while you control it from your desk. Point it at a monitor facing the stage and it becomes a speaker's confidence clock.
A plastic cube is the right tool when you want the phone in another room. This one is there when a browser is already open. You get the same move - pick a duration, start working - plus pause, a custom length, digits you can read from across a desk, and a stopwatch and interval timer on the side. It does not sync an account or keep a history of your sessions, and it does not need to.
There are no accounts, no syncing between devices and no history: Pomodoro rounds and stopwatch laps clear when you reload, so copy your laps if you need them. There is no team dashboard either.
