Online Alarm Kur：闹钟与计时器 作者： Burak Ozdemir

Online Alarm Kur lets you set an alarm or countdown timer from your browser.

To use it, click the toolbar icon, pick a time or a duration, and close the popup. When it goes off, you get a sound. You can have multiple alarms, each with its own label (like "Standup"), set to repeat daily or fire just once.

You can use it for:

• Study or work sessions
• Medication reminders
• Meeting reminders
• Wake-up alarms
• Cooking

The extension works offline and remembers your choices.
