FullCountdown is a massive fullscreen countdown timer that runs entirely in your browser — no ads, no login, no backend.

Configure your timer (time, colors, labels, alarm, loop mode) and share it instantly: every setting is encoded directly in the URL.

Highlights:

• Pick presets or set custom hours/minutes/seconds.
• Toggle a beep alarm, looping, fullscreen, progress bar, title, and more.
• Hide the UI for a clean presentation mode.
• Cycle through themes if you’re bored of the default dark one.
• Use keyboard shortcuts (because who wants to click “play” mid-focus session?).

I’ve been testing it mainly for professional scenarios — stage events, livestream countdowns, conferences, classrooms, and team meetings — basically anywhere you need a huge, crystal-clear countdown visible from across the room. The display automatically scales so the numbers take up as much screen space as physically possible, prioritizing legibility and focus.

⚙️ It’s still experimental / beta — there are rough edges, weird browser quirks, and a UI that could definitely use a designer’s touch. I’m testing different layouts and usability tweaks (like a compact navbar module for time entry).
