Editorial policy

What we publish

• Tools. Free timers, clocks and calculators that run in your browser.
• Tool guides. The explanatory text under each tool: how the tool works, which settings it has, reference tables and practical advice for the task it is used for.
• Articles. Longer explainers in our guides section on sleep, focus, cooking times, training intervals and time keeping.

Alarm Click is an independent project run by a single developer. It has no sponsors and publishes no paid or sponsored content.

How tool guides are checked

Every statement a guide makes about a tool, such as its presets, ranges, sounds, warnings or what it saves on your device, is checked against the tool's actual code. If a guide and a tool disagree, we change the text to describe what the tool really does; we do not describe features that are only planned. The full set of guides was re-checked this way in October 2026, and a guide is updated whenever the tool it describes changes.

How articles are researched

• Numbers and research findings come from published sources: government and health agencies, universities, standards bodies and peer-reviewed studies. Each article lists the sources it relies on at the end.
• Where the evidence is weak or mixed, the article says so instead of overstating it.
• Each article shows the date it was last updated.

Health and safety topics

Some tools and articles touch on sleep, exercise, blood pressure or pregnancy. That content is general information, not medical advice, and it is not a substitute for a doctor, midwife or pharmacist. Health-related calculators give estimates, and their pages say when to ask a professional.

AI tools and translations

We use AI writing and translation tools to help draft and translate text. They do not decide what is published: every page is reviewed before release, statements about the tools are checked against the tools themselves, and facts are checked against the sources described above. Translated pages are kept consistent with the English original and with the tool's interface in that language. We would rather offer fewer languages than publish half-translated pages.

Advertising

The site is funded by display advertising. Advertisers have no say in what we write, and ads are never placed so they look like part of a tool or a guide. How advertising cookies work is explained in our privacy policy.
