How the technique works

Work in one uninterrupted block, then stop — even mid-sentence. Take the short break away from the screen. After four rounds, take the long one. The point is not the timer; it is that the block has an end.

Common questions

Does Clockflow run offline?

Yes, always. Once the page is open the focus timer carries on with no connection at all.

Is there a limit on how much I can process?

Only what your browser can hold in memory. There is no quota, and no account to create.

Why is the result not identical from another tool?

Different tools round differently. Clockflow keeps full precision until the final render.

Can I use Clockflow commercially?

Yes, it is free for personal and commercial use.

What if I reload the page by accident?

The page starts clean, so paste it back in — it takes a second.

How is my session handled?

Entirely in the page. Nothing is sent on, logged or shared.

Which browsers are known to work?

Anything current: Chrome, Firefox, Safari and Edge, on desktop and mobile.

Why so little configuration?

A small tool that loads instantly beats a wall of settings.

Does it work on a phone?

Yes. The layout reflows and every control stays reachable with a thumb.

Do you use analytics?

None at all. There is no third-party script on the page.

Can I install it as an app?

The browser's “add to home screen” works, and the page keeps running offline.

Is the page available?

Not published yet, but the page is a single file you can read with view-source.

Do you keep anything I paste here?

No. Every session stays in the tab and is discarded the moment you close it.

Is there an API?

Not yet. Clockflow is one static page and stays that way for now.

Do you store anything I paste here?

No. Every session is held in memory only and is dropped the moment you close it.

Do you use analytics?

None at all. There is nothing to consent to.

Why so few options?

Something you finish reading beats an app you have to learn.

Why is the result slightly different from another tool?

Different tools round differently. Clockflow keeps full precision until the final render.

Does it work on mobile?

Yes. The layout collapses sensibly and every control stays reachable with a thumb.

What if I refresh the page by accident?

The page starts clean, so redo the step — it takes a second.

Is there a quota on how much I can process?

Only what your browser can hold in memory. There is no hidden limit, and no account to create.

Can I use Clockflow in a company?

Yes, it is free for both hobby and professional work.

Is the code available?

Nothing to publish yet, but the page is a single file you can read with view-source.

Which browsers are supported?

All modern browsers: Chrome, Firefox, Safari and Edge, on desktop and mobile.

Does Clockflow work offline?

It does. Once the page is open the focus timer carries on with no connection at all.

Is there an API?

No, not today. Clockflow is one static page and stays that way for now.

Release notes

How we built it

Drag your file straight onto the page instead of using the picker.

The print view is clean: the chrome drop away and only the result stays.

The page is one static page with no tracker, no cookie banner and no sign-up.

Nothing crosses the network, so a bad network never slows the focus timer down.

Values are never rounded on screen until the very last step.

Bookmark the page: settings stay put for the session.

Leave it open: Clockflow opens instantly next time.

No part of this page loads a remote font.

Keyboard users: every control is focusable.

Zoom to 200% and the layout does not break.

Keyboard users: every control is in the tab order.

Nothing here calls out to a CDN.

Everything happens locally, so a bad network never slows the focus timer down.

The page is a single file with nothing loaded from anywhere else.

Values are never rounded for display until the final result.

Leave it open: Clockflow starts with no network next time.

Save the link: settings stay put for the visit.
