Work timers compared: which kind keeps you on task
Drifta is an iPhone task app for ADHD that gives every task its own time window.
A work timer only helps when its length matches the problem in front of you. A 25-minute Pomodoro block suits a task you can already start, a five-minute starter timer suits one you're avoiding, and an open-ended body doubling or co-working session suits a task with no natural stopping point. Matching the timer to the task is most of what makes any of them work.
A work timer only helps when its length matches the task in front of you. A 25-minute Pomodoro block works well for something you can already start, a five-minute starter timer is built for something you're avoiding, and an open-ended co-working or body doubling session covers a task with no natural stopping point. Most complaints about timers not working trace back to using the wrong length for the job at hand.
Three timer shapes, three different jobs
"Work timer" usually means one of three different tools, and treating them as interchangeable is where most timer habits fall apart. A fixed block times a task you're already doing. A short starter times the resistance before you begin. An open-ended session times nothing at all, it borrows another person's presence to keep you moving. Grabbing whichever one is already installed, instead of picking based on which job needs doing, is the single biggest reason a timer gets abandoned after a week. Here's how the three compare.
| Timer type | Typical length | Best for | Where it fails |
|---|---|---|---|
| Pomodoro block | 25 minutes work, 5 minutes off | A task you can already start and want to protect from interruptions | Tasks you haven't started yet, since the block assumes you're already moving |
| Starter timer | 5 minutes | A task you're avoiding, where starting is the whole problem | Long, effortful work, where five minutes ends just as momentum builds |
| Open co-working session | No fixed end, set by the group or call | Tasks with no clean stopping point, or ones needing outside accountability | Requires another person's schedule to line up with yours |
The 25-minute block, and where it came from
The Pomodoro Technique dates back to the late 1980s, when Italian student Francesco Cirillo was struggling to get through his reading and started timing himself with a kitchen timer shaped like a tomato, according to accounts of the technique's history. He tested other lengths first, two minutes was too short to get anywhere and 45 minutes felt too long to sustain, and settled on 25 minutes of work followed by a 5-minute break as what actually held his attention. That number isn't universal. For a task you're already doing and want to protect, a fixed block works because it turns "keep going" into a countdown instead of an open-ended commitment. For a task you haven't started, the same block can feel like being handed a stopwatch before the starting gun.
The five-minute starter, for the task you're avoiding
A short timer has a different job than a long one: making starting small enough to actually do. Committing to five minutes on the report you've been avoiding is a much smaller ask than committing to finishing it, and five minutes is frequently enough to get past the part where starting felt worse than the task itself. The five minute start: why tiny timers work for ADHD covers why the short version tends to outperform a longer, more serious-sounding commitment for exactly this kind of task.
Open-ended: body doubling and co-working timers
Some tasks don't have a natural stopping point at 25 minutes or 5. Either the task is genuinely long, or the resistance is about staying with something dull rather than starting it. An open co-working session, working alongside someone else, in person or over a video call, on a shared timer or no timer at all, solves for presence rather than duration. Body doubling: how working near someone helps you start covers why another person's attention, even a stranger's, on a shared call tends to hold focus longer than a countdown does on its own.
Doing this at work without announcing it
A visible countdown app or a phone propped against the monitor can invite questions in an office, especially the kind that leads to explaining ADHD to someone who didn't ask. Handling time blindness at work without telling everyone covers quieter versions: a watch face instead of a phone screen, a timer running silently with just a vibration at the end, or blocking the time on a shared calendar as a generic focus block that nobody needs explained.
A worked example: Tuesday split across three timers
9:05, a report intro you've been circling for two days: five-minute starter timer, because starting is the actual problem. By 9:12 you're past the first paragraph and keep going without resetting the timer. 9:40, an already-moving task, cleaning up a spreadsheet you're already inside of: a 25-minute Pomodoro block, because the risk here is interruption, not avoidance. 11:15, a slow, dull data-entry task with no clean stopping point: a 45-minute co-working call with a colleague, camera on, both working on separate things. Three tasks, three timer shapes, chosen by what each task actually needed instead of defaulting to whichever timer was used last. Part of what makes that switching costly is real: the American Psychological Association attributes to psychologist David Meyer an estimate that switching between tasks can cost as much as 40 percent of someone's otherwise productive time. That's an argument for picking the right timer once per task block, not for hopping between three different apps to find one.
If none of the three stick
Drifta's built-in focus timer runs up to five minutes for free, matching the starter-timer use case above, with longer sessions available on Pro for tasks that need the full block. It's one timer inside the same app already holding the task list, so starting it doesn't mean opening a second app and losing the task you were looking at in the first place.
Common questions
What is the difference between a Pomodoro timer and a regular work timer?
A Pomodoro timer specifically pairs 25 minutes of work with a 5-minute break, repeated in a set pattern, a structure Francesco Cirillo settled on after testing shorter and longer intervals. A plain work timer is just a countdown with no built-in break pattern, which can work equally well or better depending on the task.
Why does a 25-minute timer sometimes make a task harder to start?
A Pomodoro block assumes you're already moving and just need protection from interruption. If the real problem is starting at all, a 25-minute commitment can feel too big, which is why a shorter five-minute starter timer often works better for tasks you've been avoiding rather than ones you're already doing.
Does a focus timer work for tasks with no clear end point?
A fixed-length timer works less well here, since the countdown ending doesn't mean the task is done. An open co-working or body doubling session, timed loosely or not at all, tends to fit better, because what's actually helping is another person's presence rather than a specific number of minutes.
How do I use a work timer without it being obvious to coworkers?
A watch face instead of a phone screen, a silent vibration alert instead of a sound, and blocking the time on a shared calendar as a generic focus block all work without drawing attention. None of it requires explaining why you're using a timer in the first place.
