Frequently Asked Questions
Quick answers about TimerHub's free timing tools.
Frequently Asked Questions
Is TimerHub really free?+
Yes. Every tool on TimerHub is free, with no account, no download, and no trial. The site is supported by unobtrusive ads.
Do I need to create an account?+
No. Open any tool and start using it immediately. Nothing is saved to our servers.
Will the timer keep running if I switch tabs?+
Yes. All timers use your device's clock rather than simple interval counting, so they stay accurate even when the tab is in the background.
Why doesn't the alarm sound on mobile?+
Mobile browsers block audio until you interact with the page. Tap the start button at least once before backgrounding the tab. Keeping the page open also helps reliability.
What keyboard shortcuts are available on the stopwatch?+
Press Space to start or stop, L to record a lap, and R to reset.
How accurate is the stopwatch?+
TimerHub measures to millisecond precision using your browser's high-resolution clock. It is more than accurate enough for workouts, cooking, study sessions, and general use.
Does TimerHub work offline?+
Once a tool is loaded, the timing itself runs entirely in your browser and continues to work even if your connection drops.
How do I report a bug or request a feature?+
Email contact@timerhub.org. We read every message and usually reply within two business days.
