Online Timer

The timer in the top right stays visible on every screen — MEMODULE, Calduo and Dayplot — so you can keep working without opening another tool. Beyond a plain countdown, the SET MENU lets you build an interval workout with a countdown, work and rest phases.

The simple timer

How it works

  1. Click the ⚙ (gear) to open the settings panel
  2. Set the time with the three sliders: Hours / Minutes / Seconds. Each row also has a CLEAR button and +1 / +5 / +10 buttons, so you can adjust one unit at a time
  3. The main display updates as you adjust it, so you can set it by eye
  4. Press ▶ to start
  5. While running, ▶ becomes ⏸ (pause)
  6. ↺ resets to the time you set

Expand, at the top of the settings panel, switches to a large full-screen display on desktop. On a phone's narrower screen, Expand keeps the same compact display and settings panel instead. On the expanded surface, END TIMER ends the Timer session and returns you to the tool underneath (compact Timer).

When time is up

  • With a sound chosen, the display shows 00:00:00 while it blinks and the sound repeats. A red stop button appears next to the digits
  • Press the red stop button to stop the sound and blink; the display returns to the time you set
  • With the sound set to None, there is no sound or blinking — it returns quietly to the time you set
  • After stopping, you can press Play again from the same duration without reopening settings

Building a workout with SET MENU

  1. Press ADD SET MENU in the settings panel
  2. A title is optional — you can save without one
  3. Pick one of three rows — Work out, Interval or Count down — then use the sliders to set that row's duration
  4. Count down (the lead-in before the workout starts) only uses seconds; Hours and Minutes are not used for it
  5. Use the SET ▴▾ buttons to change the number of sets
  6. The three buttons on the right handle ▶ (start the workout), save and delete

Saved set menus appear in a list in the settings panel. Selecting one loads it back into the editor, and the save button then updates that preset instead of creating a new one. Delete only removes the preset currently selected in the list. Starting a workout from a saved preset clears that selection highlight once it begins — the saved preset itself is not removed.

Phases run in this order:

  1. Count down (the lead-in, once)
  2. Work out
  3. Interval (rest between sets — skipped if it's set to 0 seconds)
  4. FINISH

On the expanded display, the circular face draws its progress arc in gray during Count down and Interval, and in blue during Work out.

While a workout is active, use Pause / Resume, ↺ (Reset) and END WORKOUT. Ending a workout returns you to the plain expanded countdown display. From there, use END TIMER to return to the tool.

Pausing a workout enables Gear. From Gear you can open SET MENU and edit the current plan. Pressing Start replaces the paused run and begins again from the start (including Count down when set). Closing without Start returns you to the same paused workout and does not resume it automatically.

A running or paused workout only exists while the page stays open. Reloading the page loses that in-progress workout, and you would start it again from scratch. Your saved SET MENU presets, however, stay in this browser.

Flip (desktop only)

While a workout is running on desktop, the expanded display shows INSIDE OUT and Upside down buttons.

  • INSIDE OUT — mirrors the display horizontally
  • Upside down — rotates the display 180 degrees
  • Both can be turned on at the same time

It's a visual effect only — it does not change timing or what gets saved. It is not available on mobile.

Finish sounds

Choose one under FINISH SOUND in the settings panel, and preview it once with the speaker icon next to each row.

  • Beep — a short electronic tone
  • Chime — two soft notes
  • Bell — a bell with a long tail
  • None — silent; no blink; returns to the time you set

The sound you choose is used for both the simple timer and a workout's FINISH. Sounds only play while the DESKBIBO tab stays open in your browser. If the browser is fully closed, no sound plays, and there is no OS-level push notification either.

Storage and privacy

The simple timer's settings and any saved SET MENU presets are both stored in this browser (localStorage). There is no account and nothing syncs to a cloud service.

A backup file from Export, at the bottom of the page, includes the timer's settings and saved SET MENU presets alongside the other tools' data, in the same format. Import restores them on another browser or device.

FAQ

Q. Is an account required?

A. No. There is no sign-up, and nothing is synced to a server.

Q. What happens to the timer when I reload the page?

A. The simple timer counts from a target end time, so the remaining time stays correct after a reload. A running or paused workout, however, only exists while the page is open, so reloading loses it (your saved SET MENU presets are not affected).

Q. Will the alarm sound if the browser is closed when time is up?

A. No. The alarm needs the page to be open to play. If time runs out while the browser is closed, the next time you open it, the display is already back at the time you set — with no sound or blinking.

Q. Can I use a saved SET MENU on another device?

A. Not automatically. Use Export to save a backup file, then Import it on the other device — your saved SET MENU presets move across with everything else.
