FAQ

Common Questions

Everything you need to know about using the timer

Does the timer work if I close my browser tab?

The timer will pause if you close the tab, but your settings are saved. When you return, you can resume or restart. For uninterrupted timing, keep the tab open or use fullscreen mode.

What's the longest timer I can set?

You can set timers up to 24 hours - perfect for all-day events, long work sessions, or overnight reminders. Most people use it for shorter periods like 25-minute focus blocks or cooking timers.

Will the alarm work if my phone is on silent?

Sound alerts respect your device's volume settings. If your phone is on silent, you won't hear the alarm. The timer will still show a visual notification when time is up.

Can I change the alarm sound?

Absolutely! We have several sound options - from subtle chimes that won't disturb others, to more noticeable alerts for noisy environments. You can also turn off sounds completely for silent timing.

Does it work well on phones and tablets?

Yes, it's designed to work great on all devices. The interface automatically adjusts to your screen size, and touch controls are optimized for mobile use. Many people use it on their phones for cooking and workouts.

Can I use multiple timers at once?

Each browser tab runs one timer, so you can open multiple tabs for different timers. This is handy for tracking different activities or having backup timers running.

Are my timer preferences saved?

Yes, your sound preferences and other settings are remembered between sessions. You don't need to set them up each time you visit.
