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.

Why this alarm is great for productivity

  • Repeat patterns: daily, Monday–Friday, or custom days for class schedules, stand-ups, and recurring meetings.
  • Snooze options: quick 5/10/15/30-minute snoozes to stay on track without losing momentum.
  • Fullscreen mode: a large, clean countdown you can see from across the room.
  • Client-side privacy: all settings are stored locally; calculations and audio run in your browser.
  • No sign-up, no download: works instantly on desktop and mobile with modern browsers.

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.
