Presentation Timer with Bells

A free presentation timer that rings a desk-bell "ding" for the first, second and third bell — once, twice and three times. Set each bell as minutes before or after the end of the talk, or pick a preset: a 12-minute conference talk with 3 minutes of Q&A, a 5-minute lightning talk, a 20-minute seminar or a 1-minute interview pitch. The time left fills the screen, the background changes green → yellow → red with a text label for each stage, and overtime shows as "+1:23".

How to use

1. Open Settings (top left) and pick a preset such as a 12-minute talk + 3-minute Q&A, or enter the talk length and bell times
2. Press Start (or Space) when the talk begins. The time left fills the screen and a desk-bell sound rings at each bell time
3. Bell 1 turns the screen yellow (wrap up), and the end of the talk turns it red with overtime such as "+1:23". If a bell comes after the end, it shows "Q&A" until the last bell, then "Time's up" (with no later bell, "Time's up" starts at the end of the talk)
4. Reset before the next speaker. While the timer runs, Reset needs two presses so a slip doesn't erase the time

Features

• Bells 1, 2 and 3 ring once, twice and three times with a desk-bell "ding" synthesized on the spot with Web Audio. Volume control and mute included
• Set each bell as minutes and seconds before or after the end of the talk. One-tap presets for lightning talks, conferences, seminars and interviews, with the time from the start shown next to each bell
• The background changes green → yellow → red, and each stage is also written out — Speaking, Wrap up, Q&A, Time's up — so it works without relying on color
• Switch between time left and time elapsed. Overtime shows as "+1:23", and the numbers blink once the last bell has passed. ±1 minute buttons for quick adjustments
• Fullscreen and a Zen mode that hides the buttons. Keeps the screen awake while running (in supporting browsers)
• Timing is based on the clock, so it stays accurate in a background tab. Settings are saved in your browser and can be shared by URL
