How to use a focus timer with ADHD
Set the timer for less time than feels sufficient, write down the one task it covers before you press start, and decide in advance what happens when it rings. The timer's job is not to force concentration for a fixed block. It is to make starting small enough to attempt and stopping something you can trust.
The timer is not there to make you concentrate
Most advice about focus timers assumes the hard part is staying on task once you start. For a lot of ADHD brains, the hard part is earlier than that: it is getting from "I should do this" to actually doing it. A timer solves that problem by shrinking the commitment. You are not agreeing to finish the report. You are agreeing to look at it for eight minutes. That is a much easier yes.
This changes how you should choose the number on the timer. If you pick a length that matches how long the task "should" take, you have recreated the whole task, just with a clock attached. Pick a length so short that saying no to it feels a little silly.
Choose the length by how much you are dreading the task, not by the task itself
A task you are excited about can take a forty minute timer with no trouble. A task you have been avoiding for a week needs something closer to five minutes, even if the task itself would only take fifteen. The dread, not the workload, sets the number.
Say the task is calling the insurance company about a claim. You know the call itself takes maybe ten minutes. But you have put it off for six days, which tells you the real obstacle is starting, not duration. Set the timer for five minutes covering just "find the claim number and dial." Once you are on hold, the call finishes itself.
Compare that with something you actually enjoy, like sketching out a plan for a hobby project. There the obstacle is not dread, it is the opposite problem: getting absorbed and losing track of everything else. A longer timer, twenty five or thirty minutes, fits that task fine, because the goal there is not overcoming resistance, it is giving yourself a fair stretch before you have to check in on the rest of your day.
Name the target before you start the clock
A timer with no target turns into twenty minutes of reorganizing your desk. Before you press start, say out loud or write down the one thing the timer covers: "write the first paragraph," "sort the mail into keep and shred," "find the tax document." If the target takes three tries to word clearly, that is useful information. It usually means the task is still too big and needs to be broken down before a timer will help at all.
Decide the ending rule before you need it
The moment the timer rings is exactly when your judgment about whether to continue is least reliable. If the work is going well, you will want to ignore it and keep going, which is fine sometimes and a trap other times. If the work is going badly, you will want to quit ten seconds before it rings, which throws away most of the benefit. Decide the rule in advance: when the timer ends, you finish the current sentence or step, then choose fresh whether to set another one. That five-second pause is what keeps the timer in charge instead of your mood.
What to do when the timer feels pointless
Sometimes a short timer does not work, usually for one of two reasons. Either the task is genuinely too vague to start (see rewriting vague tasks before trying another timer), or the task needs another person in the room more than it needs a clock, which is where body doubling tends to help where a timer alone does not. If you have tried three timers on the same task and made no progress, the timer is not the problem to fix.
A timer that respects how the day actually goes
Drifta's built in focus timer runs free sessions up to five minutes, which sounds short until you have used it on a task you have been dreading. Five minutes is long enough to get past the part where you are just standing at the edge of the task, and short enough that agreeing to it does not feel like agreeing to your whole afternoon. Pro sessions can run longer once a task has earned more time. The point is not the exact number. It is that the length of your commitment can match the size of your resistance instead of the size of the job.
Building the habit without overthinking it
You do not need a ritual around this. Pick a task, pick a number that feels almost too easy, name the target in one sentence, press start. If you finish it and want more, set another one. If the timer becomes something you dread setting, that is a sign the number is wrong, not the method.
Give yourself permission to adjust the number as you learn what your own resistance actually feels like task by task. A number that worked for cleaning the kitchen might be completely wrong for opening a difficult email, and neither means the timer has stopped working. It only means the task changed, so the setting should too.
Common questions
How long should a first focus timer be?
Start shorter than you think you need. Five to ten minutes is enough to break the freeze on most tasks. You can always keep going once the timer ends and the task has momentum. A long first timer just gives you more time to negotiate your way out of starting.
What if I ignore the timer and keep working?
That is a good outcome, not a failure of the method. Let the timer finish its job of getting you moving, then either restart it for another block or keep going without it if the task has its own momentum now.
What if the timer goes off and I do not want to stop?
Finish the sentence, save the file, or get to a natural pause, then decide fresh whether to set another timer. Ignoring every ending because the work feels good is how one task eats the rest of the day.
