How to use the TimerFlip online timers

Pick a tool. Press Start. Get back to work.

One site, six tools: a countdown, a Pomodoro timer, a classroom timer, a stage timer, a stopwatch and an interval timer. Pick one below to see how it runs, then read on for the float, the big-screen modes and the shortcuts they all share.

Pick a tool

How each one runs, step by step, and what its own controls do.

The main page: a single countdown from a preset or a length of your own.

Open the timer
  1. Pick a duration

    Tap one of the six presets, or set your own length.

    • Presets cover 5, 10, 15, 20, 30, and 60 minutes. The cube turns to that face, or the digital display shows the time.
    • Open Set a custom time for anything else: whole minutes and seconds, from one second up to 24 hours.
    • Picking a new duration resets the clock, so you always start from the full length.
  2. Start the countdown

    Press Start, or hit the spacebar anywhere on the page.

    • The clock counts down second by second, with a progress bar that empties as time runs out.
    • Pause and resume as often as you need. Reset puts the clock back to the full duration.
    • On a computer, Start also opens a small floating timer that stays on top of your other apps.
  3. Finish on time

    At zero the display says Time's up and the alarm chimes.

    • The chime repeats for about 25 seconds, then stops by itself.
    • Press Stop alarm, or the spacebar, to silence it early. Then Restart runs the same length again, or pick a new one.
    • Prefer silence? Turn off Sound when timer ends and the finish is visual only.

Controls

  • Custom time

    Minutes and seconds fields with their own Start button. Invalid lengths are flagged before anything starts.

  • Sound when timer ends

    A switch for the chime. Your choice is remembered on this device for next time.

  • Cube or Digital

    Switch between the 3D cube and a plain digital display. Both show the same clock; the view you pick is remembered.

Show it on a bigger screen

Every tool has both buttons, so a workout, a lesson or a meeting can run on the projector.

Full screen

Fills the screen with the clock on every tool. The control bar at the bottom keeps the main buttons in reach and hides itself a few seconds into a run. Press Escape or Exit full screen to leave. On a phone it turns sideways.

Second screen

Opens the clock alone in a new window. Drag it onto the projector or TV and click it to fill that screen. The buttons stay on your laptop, and what you press there shows on the big screen at once. It needs the projector set up as an extended display, not a mirror. On a stage, it is how the speaker gets a clock of their own.

Keyboard shortcuts

The same keys work on every tool. Shortcuts pause while you are typing in a field.

Space
Start, pause, or resume any tool. While an alarm rings, it stops the alarm.
L
Record a lap on the stopwatch.
R
Reset the tool you are on.
Esc
Leave full screen.

Your settings stay put

The sound switch, your Cube or Digital choice on the main timer, your Pomodoro lengths and your last interval plan are saved in this browser, so each tool opens the way you left it. There is no account and nothing is sent to a server.

Sound is one setting for the whole site: turning off Beeps and alarm on the interval timer also silences the countdown chime. Clearing site data resets everything. Details are in the privacy policy.

Accurate in a background tab

Browsers slow down timers in hidden tabs, so a clock that adds up one-second ticks drifts. TimerFlip stores the moment a countdown should end, or the moment the stopwatch started, and shows the difference from now. Interval beeps are queued on the audio clock when you press Start, so they land on time even behind other windows.

Floating timer in each browser

Keep any tool in view while you work in another app. It looks the same everywhere; the controls differ.

  • Chrome and Edge

    A real mini window with the clock, a progress bar, and its own Start, Pause, Resume, Stop, and Hide buttons.

  • Firefox

    Opens as picture-in-picture. The play and pause control pauses the timer; pause or mute stops the alarm.

  • Safari

    Opens as picture-in-picture. The pause control pauses the timer and stops the alarm. Closing it keeps the timer running.

  • Phones

    Float is a computer feature, so the button is hidden. Use full screen instead: it turns sideways and fills the screen with the clock.
