“These timers make me happy and help me focus.” — Filbert Ephraim Wu, maker · MIT ’28
radialtimers.com is a free timer site with a minimalist design that helps you focus and destimulate. Time here is drawn as twenty concentric rings that empty as it passes: one glance tells you how much remains, and the exact count sits below the dial.
The timers do more than count down: there are cycle timers for pomodoro and intervals, shared rooms that put a whole group on one countdown, a competitive leaderboard with live challenges, video export, and much more. Everything works in twelve languages, too.
Together, people here have destimulated 0 hours. The stats are public.
We hope you find many uses for these timers, from schoolwork to cooking. Signing in with Google unlocks more, starting with the leaderboard: your hours follow you across devices, and you compete with everyone else who keeps time here.
Invite two friends or sign in with a school address and you become a supporter, with a badge by your name on the leaderboard. Supporters keep the site free for everyone.
That will not change: the promise is in writing on Free forever.
New here? The guides are the longer reads: what a radial timer is, how to start with the pomodoro technique, study sessions that stick, and more. What changed on the site, and when, is in News.

The rings began as videos. The same timers run on PHCuber, and a timer here with a matching video can play it right on the card, with Show video one tap away.
