Frequently Asked Questions
Can I set a custom time that is not one of the presets?▼
Yes. Enter any combination of hours (0–23), minutes (0–59), and seconds (0–59) directly in the input fields. The presets are a shortcut, not a requirement.
Will the alarm play if I switch to another browser tab?▼
The alarm sound may be blocked by some browsers when the tab is not active. For reliable background alerts, enable browser notifications — you will receive a push notification when the timer ends, even if the tab is backgrounded.
How do I enable browser notifications?▼
The timer will automatically request notification permission the first time you open it. If you dismissed the prompt, re-enable it in your browser's site settings — click the lock icon in the address bar and look for 'Notifications'.
Does the timer keep running if I close the browser tab?▼
No. This is a browser-based timer and requires the tab to remain open to continue counting. For background timers, use your device's built-in clock or timer app.
Can I use this as a Pomodoro timer?▼
Yes. Set 25 minutes for a standard Pomodoro work session, then use the 5-minute preset for a short break. The alarm and browser notification will signal when each interval ends.
What is the maximum time I can set?▼
You can set up to 23 hours, 59 minutes, and 59 seconds — nearly a full day of countdown time.
