Online alarm clock — repeating alarms with built-in tones
Use this free online alarm clock to schedule precise reminders directly in your browser. Create one-time alarms or repeating alarms (daily, weekdays, or custom days), choose a built-in beep (sine, square, or sawtooth), set the volume, and snooze with a single click. For better focus, switch to the fullscreen display and keep the next alarm visible at a distance.

Tips & best practices
- Click Enable notifications to allow a native browser alert when the tab is in the background.
- Use Use now + to schedule a quick alarm (e.g., 10 minutes) for Pomodoro sessions or breaks.
- Choose the tone that cuts through your environment (square is sharper; sine is softer) and adjust the volume to taste.
- Keep the tab open so audio can play reliably. Some browsers restrict sound in inactive tabs without prior interaction.
