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
- Go to the custom timer and enter your minutes and seconds.
- Press Start — or hit the Space bar.
- 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.
Frequently asked questions
Is Tickline's online timer free?
Yes — every timer on Tickline is free, requires no account, and works in any modern browser.
Does it work if I switch tabs?
Yes. The countdown is anchored to a real end-timestamp, so background tabs stay accurate to the millisecond.
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.
