One long block for work that needs a warm-up: writing, coding, design, research. Ninety minutes of focus, then a proper twenty-minute break.
Attention tends to run in cycles of roughly an hour and a half; sleep researchers call the same rhythm the ultradian cycle. Whether or not you take the science literally, most people who do creative or technical work recognise the pattern: the first fifteen minutes are spent loading the problem into your head, the middle hour is where the good work happens, and after about ninety minutes the quality drops sharply. A 90-minute block with a real break afterwards fits that curve. A 25-minute block ends just as you have finished loading.
It is not for admin, email or memorisation. Those belong in 25-minute blocks.
Ninety minutes only works if it is genuinely uninterrupted. Before you press play: phone in another room or face-down on silent, tabs you do not need closed, the one task written in the tasks drawer. PomoSpot's "deep focus" music mode plays minimal, lyric-free tracks chosen for long sessions, and ambient layers such as rain or fire mask background noise. If you prefer your own playlist, Spotify and Apple Music both connect inside the timer.
After ninety minutes you need more than a stretch. Eat something, walk outside, lie down for ten minutes if you can. The break is part of the method, not a reward for finishing it. Two 90/20 blocks make a very productive half-day; three is a full one.
| Rhythm | Blocks per day | Best for |
|---|---|---|
| 25 / 5 | 6 to 12 | Starting, memorising, small tasks |
| 50 / 10 | 4 to 6 | Essays, reading, problem sets |
| 90 / 20 | 2 to 3 | Deep creative and technical work |
Stop, take the break, and next time use the 1-hour preset. Build up rather than pushing through a block that has already stopped working.
Yes. The timer runs in the background and the chime plays when the block ends. Keeping the tab open is enough.
Yes. PomoSpot also has a stopwatch mode with laps, and it records the time to your focus stats when you stop it.
