Online Alarm Kur lets you set an alarm or countdown timer from your browser.
Click the toolbar icon, pick a time or a duration, and close the popup. When it goes off, you get a sound and a desktop notification.
You can have multiple alarms, each with its own label (like "Take medicine" or "Meeting"), set to repeat daily or fire just once. The timer works for cooking, study sessions, workouts, or breaks.
- This extension can create rich notifications and display them to you in the system tray.
