Half an hour, on the clock
Thirty minutes is a classic block of time: a lesson segment, a workout, a meeting or a solid stretch of homework. This page opens with the timer at 30:00, so there's nothing to set up.
Use it for a run or walk, a yoga session, a study block with a break after it, practising an instrument, cooking pasta sauce or rice, limiting screen time, a quick team meeting, or a timed exam section. The ring empties as the time passes, so anyone glancing over can see how much is left.
Working with longer timers
Keep the tab open and the title shows the time left even while you work in another window. The screen stays awake while it runs on supported devices. Tick Repeat for back-to-back half hours, or use Copy link to send the timer to someone else. Want more structure? The Pomodoro timer breaks work into focus and rest, and the 1 hour timer covers longer sessions.
Frequently asked questions
Will my phone go to sleep during 30 minutes?
On most modern browsers the page asks your device to keep the screen on while the timer runs. If yours doesn't support it, the countdown still keeps accurate time.
Is 30 minutes enough for a workout?
Yes. Thirty minutes of moderate activity on most days is a common health guideline. For intervals, try the workout timer.
Will it keep running if I switch tabs or lock my screen?
Yes. The timer works from your device clock, so it stays accurate in a background tab, and the tab title shows the time left. If your phone locks, the countdown carries on, but some phones delay sound until you unlock, so keep the screen on for anything important.
