Frequently Asked Questions
Will the alarm work if my computer goes to sleep? +
No. The alarm runs in your browser tab, so the computer must stay awake and the tab must remain open. Adjust your system's sleep settings if you need the alarm to fire unattended.
Can I set more than one alarm at a time? +
Yes. Click Add Alarm as many times as you need. Each alarm has its own time, label, and sound setting. You can enable, disable, or delete each one independently.
How do I stop the alarm once it goes off? +
Click the Dismiss button that appears when an alarm fires. The sound will stop immediately and the alarm will be marked as triggered.
What alarm sounds are available? +
There are four sounds, all generated using the Web Audio API: a classic beeping pattern, a rising tone sweep, a gentle chime, and a rapid pulse. No audio files are downloaded.
