30 Minute Countdown Timer

Click Start to run a 30 Minute Countdown Timer. It’s pre-set to 30:00, plays a clear alarm at zero, and works smoothly on phone or desktop.

How it works

• Start to begin

• Stop to pause, Start to resume

• Reset returns to 30:00

• Edit to change sound, volume, loop, or switch to a target date & time

• With Edit, you can also set any custom duration (hours, minutes, seconds)

• Optionally, set a specific date & time countdown instead of a fixed duration

Shortcuts

• Space = start/pause, E = edit, S = stop, R = reset

Keep this tab open while it runs. On mobile, avoid locking the screen for uninterrupted timing.

Great for

Pomodoro focus sessions, study blocks, lesson transitions, quick meetings, writing sprints, and light workout sets.
