Speedy Timer

Use quick select buttons (+30s, +1m, +5m) or adjustment buttons (-1m, -30s, +30s, +1m) to modify time.

Enter time in any of these formats:

Simple number: Enter a whole or decimal number (e.g., 5 or 2.5 for minutes)
Clock format: Use colons (5:30 for 5m 30s, 1:30:00 for 1h 30m)
Shorthand: Use h/m/s (1h30m, 90s, 2h30m15s)
Mixed: Combine formats freely (1:30:15 or 1h30m15s)

The timer continues in the background even if you switch tabs.

A sound will play when the timer ends - choose between single or repeating sound in Settings.

The page title will update to show remaining time and notify when finished.

Toggle sound and theme using the buttons below the timer.

Select from different color themes in Settings.

Use fullscreen mode from Settings for better visibility.
