About
RepeatingTimer.com is a free online tool that runs repeating countdown timers in your browser. It was built around a simple goal: provide a fast, distraction-free timer that loops automatically — without forcing you to download an app, sign up, or watch ads in the middle of your workout.
What it does
The site offers a customizable timer on the homepage and a growing library of one-click presets for popular use cases — Pomodoro, Tabata, HIIT, meditation, stretching, boxing rounds, EMOMs, study sprints, and more. Each preset is a permanent URL you can bookmark.
How it's built
The site is plain HTML, CSS, and JavaScript — no tracking, no analytics beyond what's standard, and no data collection. The timer engine uses real-time deltas, so it stays accurate even when the tab is in the background, and on mobile it requests a wake lock so your screen doesn't sleep mid-workout.
