Custom Visual Countdown Timer

Visual countdown timer with smooth radial sweep, custom styles, and infinite colour options. Features full screen display, millisecond precision, acoustic Tibetan singing bowl chimes, and an always-on-top floating Picture-in-Picture window. 100% free to use with no paywalls, no popups, and no accounts required.

How to Use the Custom Timer

  1. Set Any Duration: Tap the Custom button or click directly on the time readout numbers to open the duration picker. Type your desired minutes and seconds and click Set Duration.
  2. Fine-Tune with Keyboard or Wheel: Press + or − on your keyboard, click the stacked arrow buttons in the stepper cluster, or simply roll your mouse wheel over the watch face to add or subtract minutes without resetting your clock.
  3. Start & Track Visual Progress: Tap Space or click START. The outer arc sweeps clockwise smoothly, giving you an instantaneous peripheral visual sense of remaining time.
  4. Float with Picture-in-Picture: Press P or click the floating window icon to keep the dial visible on top of your desktop apps while taking notes, writing code, or presenting slides.
  5. Acoustic Zen Chime: When the countdown reaches zero, a harmonic Tibetan singing bowl chime plays, signaling your transition gently without jarring buzzers.

Frequently Asked Questions

How do I set a custom countdown duration?

Click the "Custom" pill above the dial, or click directly on the time readout numbers (e.g. 05:00). A clean modal will appear where you can enter any minutes and seconds from 10 seconds up to 99 minutes. You can also scroll your mouse wheel over the dial to quickly add or subtract minutes on the fly.

Can I keep the timer on top while working in other tabs or applications?

Yes! Tap the Picture-in-Picture icon (or press the P key). This pops the live countdown dial into a native, resizable floating window that stays on top of your browser windows, word processors, spreadsheets, code editors, and video calls.

Does this timer stay accurate if I switch tabs?

Yes. oTimers calculates elapsed time using high-resolution hardware timestamps (performance.now()). Even when your operating system or browser aggressively throttles inactive background tabs, the countdown remains accurate down to the millisecond.

What sound plays when the countdown completes?

Instead of an abrasive digital buzzer, oTimers generates an acoustic Tibetan singing bowl / Zen gong chime directly using the browser native Web Audio API. You can mute the sound at any time by pressing M or toggling the speaker icon in the top navigation.

Can I change the timer colour and visual style?

Yes. Click the palette icon in the top right to customize your countdown face. Choose between Electric Cyan, Ocean Blue, Emerald Green, Amber Gold, Crimson Red, or High-Contrast Monochrome.

Are there keyboard shortcuts for hands-free control?

Yes. Press Space to Start or Pause, R to Reset, + or - to add or subtract 1 minute, F for distraction-free Fullscreen, P for Picture-in-Picture, and M to mute audio.
