Online Alarm Kur: Alarm Clock & Timer

Alarm clock and countdown timer in your browser.

Online Alarm Kur is a browser extension that lets you set an alarm clock or run a countdown timer without opening a website. You can use it for waking up, meeting and medication reminders, study or work sessions, cooking, and workouts. Once you set an alarm or timer, it keeps running in the background. ➤ What you can do • Set one-time, multiple, or repeat alarms with custom labels and sounds. • Choose from timer presets or set custom hours, minutes, and seconds. • Snooze for your chosen duration. • Switch to dark mode, set volume and notifications, or change language. ➤ Why choose Online Alarm Kur? • Set alarms and timers directly from your browser toolbar. • Clean, simple interface focused on alarms and timers. • Supports multiple alarms and works offline. ➤ Where is my data stored? Alarm and timer history and presets are stored locally in your browser. ➤ What if my device goes to sleep? Browser alerts depend on your Chrome settings, system notifications, and your device's volume and power settings. An alert may appear after your device wakes instead of at the exact time. For critical reminders, disable sleep mode.
