Guides
Practical ways to use timers — written by the people who build them, with real test data behind the advice.
Study Timers: How to Time Your Revision
Pomodoro focus blocks, timed past papers, spaced review — with a sample timed study session you can copy tonight.
Read the guide →How accurate is a browser stopwatch?
We measured setInterval drift, the 4 ms clamp and background-tab throttling in a real browser.
Read guide →What happens to timers in background tabs?
We hid a page and measured it: 1-second and 100 ms timers clamped when the tab went to the background.
Read guide →Cooking Timers: Doneness You Can Trust
Timing tables for eggs, steak, pasta and roasts, carryover cooking, and how to chain multiple timers without burning anything.
Read the guide →Workout Timers: Intervals Done Right
Tabata, HIIT and EMOM structures, rest ratios that actually match your goal, and programming a session in the interval timer.
Read the guide →Why your phone alarm fails
Silent switch, Focus mode and battery limits on phones - and why web timers share the same wake-up problem.
Read guide →Does requestAnimationFrame keep time?
We measured rAF vs setInterval for timer displays - frame-rate drift and what happens when the tab is hidden.

We're expanding the guides with the engineering side of timing: how browser timers stay accurate (and why most don't), what happens to timers in background tabs, measured clock drift across devices, and how alarm sounds work on iOS. If there's a timing topic you want covered, tell us.
