How to Choose a Planner or Diary for ADHD

Buying a nice diary feels like half of starting to use that diary. The cover is lovely, the paper is good quality, the sections are well thought out. You write on the first page with care, on the second with a little less care. By the third week the diary is lying at the bottom of your bag. I say this as someone who knows: the problem is not whether the diary is nice or not.

When choosing a planner in ADHD, the real question is not "which is the best" but "in how many seconds can I open it during the day, and can I write everything into it." In this article I will compare paper and digital by these two measures. I will not name brands, because what decides the choice is not in the brands.

What exactly a planner solves

A planner's job is to take what you cannot hold in your head out of your head and put it somewhere. In ADHD this job is especially important, because difficulty with executive functions such as working memory and planning is common in this picture (Faraone et al., 2021). In practice I live it like this: remembering something to be done later, at that moment, is one of the areas I struggle with. One of the guiding ideas in Barkley's (2015) approach to ADHD is this too: moving information that cannot be held inside to the outside, to a place where you can see and touch it.

So a planner is not a motivation tool. It does not make you eager, it does not give you the strength to start. The only thing it does is stop the knowledge "I was going to do this" from falling out of your head. Even this modest job changes many people's days, but knowing from the start that writing does not replace doing reduces disappointment. If you cannot start the task written on the list, that is a separate matter, and I cover it in the article on not being able to start a task.

Paper: what it gives, what it takes

The biggest plus of paper is that it is visible. If it is lying open on the desk, it is there. It sends no notifications, it does not pull you to another app, its battery does not run out. When you turn the page, what you have is what is on it. For some people the handwriting itself is calming. As someone who writes a diary, I like the rhythm of the pen, but I cannot say that this holds for everyone, or that writing by hand has been shown to improve remembering. The research on this is limited for adults with ADHD.

The cost of paper is clear too. It can get lost, be forgotten at home, be crushed in a bag. Once it is lost, everything in it is lost as well. You cannot search: you find the answer to "what was it the doctor said last month" by turning pages one by one. Recurring tasks have to be rewritten every week, and because it is boring, that is the first part to be abandoned.

If paper suits you, my suggestion is to get something thin and light to carry, and to attach the pen to it. The two minutes spent looking for the pen are reason enough not to open the diary.

Digital: what it gives, what it takes

The pluses of digital are concrete: it is with you everywhere, it is backed up, you can search, you set up recurring tasks once, and a reminder rings at a set time. For someone with time blindness, a notification that rings on time is something paper cannot give.

The minus is this: to open the list you open the phone, and inside the phone there are other things in front of you before the list. The study by Mark and colleagues (2008) reports that work that is interrupted both speeds up and creates tension. That study was not done with people with ADHD, but my day-to-day observation is that in ADHD this is even more pronounced. This is not evidence, it is an observation. If the moment you reach for the phone to look at the list you see three notifications, your chance of reaching the list falls.

The second trap of digital is the number of settings. Colors, labels, filters, views, templates. Because setting up is enjoyable, setting up can take the place of the real work. I described this pattern in detail in the app hopping article.

Three questions to ask yourself when choosing

Stop comparing the features of the tool and look at your own behavior.

When something comes to mind, in how many seconds do I write it down? If the answer is over ten seconds, that item will not get written. A paper notebook is fast if it is next to you and open. A phone app is fast if it is in the bottom row of the home screen. If it is inside a folder, three taps away, it is slow.

Does today's page open by itself? When you open the app you need to see the "today" screen, not a search that will take half an hour. Same with a diary: is the bookmark or the elastic on today's page?

Does it break if it gets messy? When you skip a week, does the tool punish you? Past days staying red and piling up can be motivating in an app; if it creates shame in you, turn it off. On paper, an empty page does not create shame, which is why it is more durable for some people.

Answering these three questions is worth more than the hours you would spend in a store or an app store. If it were me and I were stuck between two options, I would try both for two weeks each, one after the other, and look at which one I missed fewer days with.

The one-system rule

There is a more important decision than choosing a planner: how many. The answer is one. In a setup where appointments and to-dos sit in two separate places, the first job every morning becomes deciding "which one will I look at," and deciding is exactly the tiring thing. I explained at length why all tasks should go into a single place in the one-list rule article.

For those who want to use two tools, I suggest this line: one is the place for time-bound things (appointments, meetings, deadlines), the other is the place for things with no time (to-dos). But it is essential that an item lives in only one place. If you write the same thing in both, a contradiction starts on the day you forget to update one.

The three-month rule is important too. Promise that you will not change the tool for at least three months. After three months you can say "this does not suit me," but that decision will have been made not because you got bored in the first week but with knowledge drawn from three months of use.

How to set it up in the first week

Keep the setup short. On the first day, do only two things: write today's appointments and what has to be done today. Categories, colors, project structure come later, if needed.

Let the place of the diary not require a decision. On the table where you make your coffee, or on the home screen of your phone. This is the idea of putting things in front of your eyes applied to a planner; the details are in the visible place system article. Fix the time of opening too: a sentence like "after I put on my first coffee in the morning, I open the diary." The review by Gollwitzer and Sheeran (2006) shows that intentions whose time and place are set beforehand are carried out more often.

Once a week you also need to sit for fifteen to twenty minutes and clean the list. Deleting items that will not be done, carrying over or letting go of last week's unfinished ones. If you skip this, every planner ends up a junkyard. How it is done is in the weekly review article. If you want to empty what is in your mind before moving it into the diary, a brain dump is a good first step.

Where it does not hold

A planner is not enough on its own when the workload is very large. For someone with twenty appointments a day, the problem is not the diary, it is the calendar itself. And in a period of depression or heavy burnout, even the best system may not get opened. In that period, instead of questioning yourself with "why am I not using it," if there is a treatment such as medication or therapy, it is better to talk to your doctor about it. A planner does not replace treatment; it is a tool that stands beside it.

I also have to be honest on the research side. In adult ADHD there are studies showing that programs targeting organization and planning skills work (for example the randomized study by Solanto and colleagues in 2010), but these are mostly structured programs accompanied by a therapist. There is no data to say that simply buying a diary gives the same effect.

What stays with me

In my view the right planner is the one that embarrasses you least and takes the least fiddling. Being beautiful is a plus but never the main condition. Both paper and digital work, and both get abandoned. The difference is which of them leaves less room for your reasons for abandoning.

My suggestion is this: this week choose one of the two, just one. Keep the decision short, because stretching the choice is also a kind of procrastination. If three months from now you can look at the tool in your hands and say "I still open it," you have made the right choice, whatever the brand.

If you want a more concrete start, there is the checklists page on the site, and you can begin from there with a daily list. Paper or screen, it makes no difference.
