Free online timer with alarm

Tickline's online timer lets you set any duration, start it with one click, and hear a looping alarm when time is up. It runs entirely in your browser, works offline as a Progressive Web App, and stays accurate even when the tab is in the background.

How to use the online timer

  1. Go to the custom timer and enter your minutes and seconds.
  2. Press Start — or hit the Space bar.
  3. When the countdown hits zero, the alarm plays and a popup appears with quick actions.

Why it beats a phone timer

  • No app install — it works in any browser.
  • The alarm loops until dismissed, unlike most default phone timers.
  • Background-tab accuracy means switching apps won't drift the finish time.
  • Keyboard shortcuts (Space, R, F) make it fast to control from a laptop.

Can I set a custom duration?

Yes. Use the main timer at tickline.app to enter any minutes and seconds, or pick one of the preset timers.

Does the alarm loop until I dismiss it?

Yes. The alarm keeps playing until you close the time-up popup, so you won't miss it across a room.
