When this split works
Use it for revision, inbox cleanup, or any task you keep postponing.
The classic 25/5 split is the version most people meet first, and it is a good default for studying, admin work and creative tasks. Twenty-five minutes is long enough to make real progress and short enough that starting feels cheap. The five-minute break is deliberately small: stand up, drink water, look out of a window.
Resist opening a feed, because a short break that turns into twenty minutes breaks the rhythm the method depends on. After four focus rounds the timer offers a fifteen-minute long break, which is enough to eat something or take a short walk before the next set.
How to use this timer
Press start and leave the tab open. The timer uses absolute end times, so it stays correct after sleep, tab switching or a throttled background tab.
- Choose a preset or set your own focus, short-break and long-break lengths in the settings panel.
- Start the focus block and work on one task. Press Space to pause, S to skip and R to reset.
- Take the break the timer offers. Enable auto-start if you want the next block to begin on its own.
