About Timerjoy
Timerjoy is a free, no-signup web app for every kind of countdown, timer, and date calculation. No accounts, no popups. The whole site loads in under a second on a slow connection and works offline once you have it open.
Why this site exists
In early 2026 I was timing pasta and needed an online timer. Every result I found had a cookie banner, a newsletter modal, three banner ads, and a countdown that drifted because the page was busy rendering tracking scripts. I closed the tab and built this instead.
The goal: every timer or calculator should load in under a second, work on any device, and do exactly one job extremely well. The countdown uses the browser's monotonic clock so it stays accurate even when the tab is in the background. The alarm plays through. There is no signup. There never will be.
Who built it
Hi — I'm Kirill Yevdokimov, a Senior Product Designer with 10+ years building tools used by hundreds of thousands of people. My main work is on Uxion.ai, an AI design-research platform. Timerjoy is a side project built to scratch a personal itch and grew into a small ecosystem of 1,400+ free utility pages.
The visual design follows the Dieter Rams / Braun tradition: every element earns its place. No decorative noise, no skeuomorphic shadows, no attention-seeking animations. The interface should fade out so the timer and your task stay in focus.

How content is researched and written
Most tool pages ship per-slug context written specifically for that timer, technique, or calculation — not generic aggregator copy. Some clusters (chess time controls, boxing rounds, egg cooking, breathing exercises) are hand-curated entry by entry. Larger clusters (calendars, age calculators, days-from-today) use content generators with hand-coded branching by month, generation, or duration band — so each page reads differently from its neighbors, but the underlying logic is mine, not LLM-generated.
Where standards bodies exist, content cites them directly: ADA for tooth-brushing, AIBA / WBC for boxing rounds, FIDE for chess time controls, NASA / US Naval Observatory for astronomy timing, IANA tzdata for time-zone rules.
For health-adjacent topics — caffeine half-life, breathing exercises, contraction tracking, prayer times — content cites the relevant clinical or religious authority where one exists. We do not publish medical, legal, or financial advice; for those, see a qualified professional.

Privacy
- ·No accounts, no login, no personal-profile creation.
- ·Tool input — birth dates you type into the age calculator, contraction times, fasting windows, caffeine doses — stays in your browser and is never sent to a Timerjoy server.
- ·Site uses Google Analytics for aggregate traffic counts (page views per URL, country-level geography, referrer source). GA does set a cookie and observes your IP to count uniques — that is standard for GA, but it is not "no tracking." If you block GA in your browser, the site works fine.
- ·See the Privacy Policy for the technical details.
Honest note: the source code is currently in a private GitHub repo, so the data-handling claims above can't be independently verified today. If trust matters to you, block GA in your browser and the input-stays-local claim becomes verifiable from the network panel.
