Free online 60 minute timer
A 60 minute timer that scores your hour
One hour, one task. TimerDuel splits your 60 between two clocks — focus and break. Tap to switch when your mind drifts. At the buzzer, you know exactly how much of that hour was real work, and how much was you pretending.
Why 60 minutes is the default work block
An hour is the unit your calendar already speaks. It's a long-enough chunk to ship something real, short enough to do three or four times a day without burning out. The trick isn't fitting work into the hour — it's measuring what fraction of that hour was real focus.
FAQ
Is 60 minutes a good focus length?
Yes — 60 is the natural unit of work for most adults. One full hour, one task, one focus block. It matches calendar slots, ultradian rhythms, and how meetings are scheduled.
Is the 60 minute timer free?
Yes — free, no signup, no install. Works in any browser.
How long should the break after 60 minutes be?
10–15 minutes. Get away from your screen entirely. Real recovery is what makes the next 60 possible.
Won't my focus drop after 45?
It might — that's exactly why TimerDuel measures it. If your focus rate tanks in the last 15, you'll see it. Then you know whether to stick with 60 or drop to 45 next time.
Can I run it in the background?
Yes. Open in a tab, switch away, it keeps running. When time's up you get a notification. The chess-clock keeps counting even if you minimize the window.
