Countdown, Pomodoro cycles, or long focus blocks — with ambient sound and a gentle bell.
A free online timer sounds like a solved problem, but most timer apps interrupt you with
ads, require a signup, or default to a jarring alarm. This one doesn't. It's a no-signup
countdown, Pomodoro, and Focus Block timer that pairs quietly with ambient background
sound and ends sessions with a gentle bell instead of a shock. Pick a Quick Template
(Study 25/5, Deep Work 50/10, Rest 10, or Flow 90), choose a plain countdown, or switch to
Pomodoro mode for structured work/break cycles with automatic long breaks after a set number
of rounds.
It's built for anyone who wants a Pomodoro timer without installing an app — students
timing study blocks, remote workers structuring a deep-work session, or anyone who just
wants a simple countdown with a calming background sound (rainfall, brown noise, a Tibetan
bowl) instead of silence. Everything runs in your browser: no account, no tracking, and
your settings (bell sound, auto-restart, long-break length) are remembered locally between
visits.

Ambient Timer — Frequently Asked Questions
Is this timer really free with no signup?
Yes. There's no account, no app install, and no ads — it runs entirely in your browser, and your last-used settings (bell sound, duration, auto-restart) are saved locally so you don't have to reconfigure it each visit.
What's the difference between Countdown, Pomodoro, and Focus Block modes?
Countdown is a plain single timer for any duration. Pomodoro mode runs 25-minute work intervals with 5-minute breaks, with an optional longer break after a set number of rounds. Focus Block mode uses a 50/10 split, better suited to people who find 25 minutes too short for getting into deep work.
Can I use a custom duration instead of the presets?
Yes — switch to Countdown mode and set any duration from 1 to 240 minutes in the Duration field, or start from one of the Quick Templates (Study 25/5, Deep Work 50/10, Rest 10, Flow 90) and adjust from there.
Does the timer keep running if I switch tabs or lock my screen?
Yes, the countdown continues in the background and the bell still plays when the session ends, so you can switch to another app or lock your phone without losing track of time.
Why pair a timer with ambient background sound?
Consistent background sound — rainfall, brown noise, or a soft Tibetan bowl loop — helps mask sudden environmental noises that break concentration, and many people find a steady ambient layer makes long focus or study blocks feel less mentally fatiguing than working in silence.
Can I choose a different bell sound for when the timer ends?
Yes — pick from several bell/chime options in the timer settings. Your choice is saved locally so it stays selected the next time you open the page.
What does auto-restart do in Pomodoro mode?
When enabled, the timer automatically starts the next work or break interval as soon as the current one ends, so you can run several Pomodoro cycles back to back without manually restarting each one.
Is my timer history or settings data sent anywhere?
No. Your last-used duration, mode, and bell choice are saved only in your browser's local storage — nothing is uploaded to a server, and there's no account involved.
How is this different from Focus Mode's built-in timer?
This page is a focused, standalone timer with Pomodoro and Focus Block presets built in. Focus Mode's timer is part of a fuller immersive session that also includes a fullscreen visual and optional breathing guide layered on top.
Do I need to sign up or install anything to use this timer?
No — it runs entirely in your browser with no account, no download, and no payment. It also works offline once the page has loaded, since ASMR Sanctuary is a Progressive Web App.
