⏱️ Online Countdown Timer

No, the timer requires the browser tab to remain open to continue counting down. However, you don't need to keep the tab visible or in focus – you can switch to other tabs, minimize the browser, or even lock your screen. When the timer completes, you'll receive both a visual alert and an audible notification (if you've enabled browser notifications). For best reliability, we recommend keeping the browser window open rather than closing it entirely.

Yes! Simply open multiple browser tabs or windows of Clock7 and set different timers in each one. This is incredibly useful for complex activities requiring multiple timing elements – for example, when cooking a multi-course meal, running circuit workouts with different interval durations, or managing several time-sensitive tasks simultaneously. Each timer operates independently, so one finishing doesn't affect the others.

You can set timers up to 99 hours, 59 minutes, and 59 seconds – that's nearly 100 hours or more than 4 full days. This generous maximum accommodates virtually any timing need, from marathon cooking projects to lengthy fermentation processes, extended work sessions, multi-day experiments, or any other long-duration timing requirement. Most users never approach this limit, but it's there when you need it.

Absolutely! The timer is fully responsive and works beautifully on smartphones and tablets of all sizes. The interface automatically adapts to smaller screens while maintaining full functionality. You can even add Clock7 to your phone's home screen for quick access (tap the share/menu button in your browser and select "Add to Home Screen"). This creates an app-like experience without consuming precious phone storage.

Yes! Check the "Loop timer" option before starting your countdown. When enabled, the timer will automatically restart with the same duration after reaching zero. This feature is perfect for interval training (repeated work/rest cycles), meditation practice with regular bells, cooking tasks requiring multiple identical timing intervals, or any repetitive activity where consistent time intervals are crucial. The loop continues until you manually stop it.

Yes! Before starting your timer, click the "Alert Sound" dropdown to choose from Bell, Chime, Alarm, or Notification sounds. Each offers a distinct auditory character – Bell is gentle and classic, Chime is melodious and pleasant, Alarm is urgent and attention-grabbing, and Notification is subtle and modern. Pick the sound that best matches your environment and timing purpose. Your sound preference is saved for future timers.

No account required! We believe time management tools should be instantly accessible without barriers. Simply visit the website and start timing immediately – no registration, no email verification, no password to remember. Your recent timers and preferences are saved locally in your browser using localStorage technology, providing personalization without compromising your privacy through account systems.

Yes! When your timer reaches zero, you'll receive both visual and audible alerts. The page displays a prominent completion message, plays your selected alert sound, and (if you've granted permission) sends a browser notification that appears even if you're using other tabs or applications. These multi-layered notifications ensure you don't miss your timing cue, regardless of what you're doing.

Absolutely! Once your timer is running, a Pause button appears. Click it to freeze the countdown at any moment – the timer remembers exactly where you stopped. When you're ready to continue, click Resume and the countdown picks up from the paused time. This flexibility is invaluable when interruptions occur or when you need to temporarily halt a timed activity without starting over from scratch.

Recent Timers automatically saves your recently used timer durations for quick access. If you frequently use a 15-minute timer for coffee brewing or a 45-minute timer for focused work sessions, those durations appear in your Recent Timers list. Simply click a saved timer to instantly set up the same duration again – no need to manually enter the time. This feature dramatically speeds up your workflow for repetitive timing tasks.

Yes! Thanks to Progressive Web App (PWA) technology, once you've loaded Clock7 in your browser, the timer continues functioning even if you lose internet connection. The countdown operates entirely in your browser using JavaScript, requiring no server communication once the page has loaded. This offline capability ensures reliability in any environment – home, office, outdoors, or anywhere connectivity might be unreliable.

Yes, completely free with no limitations! All features – quick timers, custom durations up to 99 hours, looping, custom sounds, recent timers, offline support – are available at no cost, forever. No hidden premium tier, no feature restrictions, no ads (currently), and no payment required. We believe essential productivity tools should be universally accessible. Quality time management shouldn't depend on your budget.
