Managing Multiple Timers
One of Clock7's most powerful features is the ability to run multiple countdown timers simultaneously. This is perfect for complex tasks that require tracking several durations at once.
Setting Multiple Timers

Managing Individual Timers
Each timer can be controlled independently:

Pro Tips for Maximum Effectiveness
⏱️ Preset Common Durations
Keep a list of your frequently-used durations handy. For example: 5 min (coffee), 20 min (workout), 45 min (deep work). This saves time when setting timers.
🔊 Test Volume First
Before setting an important timer, test the alarm sound at your current volume level. Make sure it's loud enough to hear from where you'll be.
🔔 Enable Notifications
Always click "Allow" when your browser asks for notification permission. This ensures you'll be alerted even if the tab is in the background.
📱 Keep Tab Open
Don't close the browser tab while timers are running. Minimize or switch tabs is fine, but closing the tab will stop all timers.
🎯 Be Specific
When using multiple timers, be very specific about durations. Round numbers (5, 10, 15 min) are easier to track than odd numbers.
🔄 Use Reset for Repeats
If you're doing repetitive timed tasks (like interval training), use the Reset button rather than setting a new timer each time. It's much faster!
⚠️ Common Mistakes to Avoid
- Closing the browser tab (timers will stop)
- Setting device to Do Not Disturb (you won't hear the alarm)
- Muting your device audio
- Not testing the alarm volume beforehand
- Letting your device go to sleep during long timers
- Relying solely on browser timer for critical tasks (always have backup)
