30-minute timer
A half hour of focus, already set. Press start.
Thirty minutes is the round number most people actually reach for: a half-hour block that maps cleanly onto a calendar and gives you a few more minutes of runway than a classic Pomodoro.
The timer above is set to 30 minutes with a 5-minute break behind it. Press start; nothing to install.
What it is for
When a 30-minute timer helps.
Time-blocking a calendar
Half-hour blocks line up with how calendars are already carved, so focus time can be booked like anything else.
Work with a warm-up cost
Thirty minutes gets you past the setup tax — opening the file, remembering where you were — with real working time left over.
Fitting focus into gaps
Long enough to be worth protecting, short enough that two of them fit in a lunch break or a gap between meetings.
Keeping the streak visible
Every completed 30 minutes grows a plant, so the day's focus is visible as a field rather than a number.
Questions
30-minute timer, answered.
- How do I start a 30-minute timer?
- Press start — the timer above is already set to 30 minutes. It runs in your browser and stays accurate if you switch tabs or lock your screen.
- Is this 30-minute timer free?
- Yes, free and with no account needed. Signing in only saves your garden and history across devices.
- Why use 30 minutes instead of 25?
- It slots into a calendar without arithmetic, and the extra five minutes over a classic Pomodoro is often exactly the runway a piece of work needs to get past setup.
- What break follows the 30 minutes?
- A 5-minute break follows by default, and then the next 30-minute block. You can change either length in the timer settings.
