One Swiss Knife in the exact shape of your life.

Focus Timer

A private focus timer in one HTML file on your machine: no account, no cloud, no server to talk to.

Live · runs in your browser · no network

This is not a screenshot. It's the real tool, running right here: go on, put something in it.

Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.

You sat down to work at nine, and at nine-forty you were reading about lighthouse keepers. Focus Timer is the old kitchen-timer trick, kept in a browser tab: pick a stretch of honest work, start it, and stay with it until it's done. The timer isn't strict with you. It's just present, which turns out to be enough.

Standing facts

In ten years

Whatever you put in stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of focus timer entries is a decade of your own handwriting, kept in a document you can back up like any other.

If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.

Getting your data out

Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.

Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.

Who else sees this

Nobody. Your entries never leave the file on your own disk. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Productivity tools →

Questions people ask

01

How do I use the Focus Timer?

Start a work stretch, work until it ends, take the break you've earned, repeat. It's the pomodoro idea without the app-store clutter — one tab, one timer, back to work.

02

Is the Focus Timer good for studying?

It's ideal for it. Students, writers, and anyone doing long-form desk work tend to get the most from working in timed stretches — the timer holds the boundary so your willpower doesn't have to.

03

Does the Focus Timer work offline?

Yes, completely. It's a single HTML file that runs in your browser with no account and no connection needed — nothing about your work sessions leaves the page, and the file is yours to keep. Try the live demo on this page; it's the real thing.
