What to look for in a to-do list app when you have ADHD

Search for the best to-do app and you'll get a list ranked by features. Integrations, views, collaboration, natural-language dates. With ADHD, that ranking is close to upside down. The apps that win on features are often the ones that quietly stop being used.

This isn't a list of apps. It's a list of what to look for in one, what to be wary of, and how to find out in a week whether it'll survive.

Start with the honest question

The question isn't "which app is most powerful?" It's "which app will I still be opening in a month?" Those are different apps. Powerful tools have upkeep. Upkeep is a stream of small, boring decisions. Executive function difficulties make small boring decisions expensive, so the upkeep stops, the app goes stale, and stale is worse than nothing.

So the things to look for are mostly about how little the app asks of you.

Look for these

Adding a task is one step

Type, Enter, done. If the app asks you where the task goes, when it's due, or how important it is before it'll save it, you'll start "remembering things for later" instead. Capture has to be free.

One list, not many

Multiple lists means deciding which list, then checking several places, then trusting none of them. You want one place where everything lives, and some way of scanning it without reading every line.

A single "next" position

Priority levels ask you to rank everything. What you actually need is one slot for the one thing you're doing next. That replaces ranking with a single decision, made once.

Grouping that costs nothing

Colours or simple labels you can apply in one tap and ignore without consequence. Not projects that need tasks filed into them. Not tags that need applying consistently.

A timer attached to the task

Starting is the hard part with ADHD. A short timer you can start on a specific task, with a big visible countdown and a chime at the end, turns "work" into "twenty minutes on this". If it lives in the same app as the list, you won't have to set it up each time.

Finishing feels like something

Ticking a task off should be a moment, not a fade. Some feedback, a running count of what you've done today, completed items you can still see. Immediate, visible reward is the kind that works.

Undo

You will tick the wrong thing and delete the wrong thing. If recovering from that is hard, you'll start being careful, and careful means slow, and slow means you stop using it.

Works where you are

On your phone, in your browser, without a login wall every time. The moment it's a hassle to open, it doesn't get opened.

Be wary of these

Due dates on everything

Dates feel responsible. Then you miss a day, and the app shows a wall of overdue red, and you stop opening it. Deadlines that genuinely matter belong in a calendar. A to-do list is for what, not when.

Deep hierarchy

Projects inside areas inside workspaces. Every level is a filing decision, and every filing decision is a place to stall. It also hides tasks, and hidden tasks don't exist for an ADHD brain.

Setup that takes a weekend

If you're excited about building the perfect dashboard, that excitement is doing the work, and it runs out. The app has to be useful in the first five minutes with nothing configured.

Streaks and guilt

Habit streaks and "you have 47 overdue tasks" notifications are designed to motivate. With ADHD they tend to shame instead, and shame makes you avoid the app.

Everything in one app

Notes, docs, calendar, tasks, wiki. The more it does, the more places there are to be distracted inside it, and the more it becomes a thing to tinker with rather than a list to work from.

Test it for a week, not an afternoon

The first day tells you nothing. Everything's fun on the first day. Here's a better test:

1. Day one: put everything in. All of it. See how adding feels when there are forty items, not four.
2. Days two to five: use it without configuring anything. No settings, no new structure. Just add, pick, do, tick.
3. Day six: ignore it completely. Don't open it.
4. Day seven: open it. Is it still useful, or does it need catching up? Does it make you feel bad?

The day-seven feeling is the real answer. An app that's fine after being ignored is one you can keep. An app that needs tidying is one you'll abandon.

Where OneList fits, and where it doesn't

We built OneList around the first list. One list for everything. Tasks grouped by five colours instead of projects or tags. A Now section at the top that you star a task into. A 10, 20 or 25-minute focus timer on that task with a big countdown in its colour, the time in your browser tab and a chime at the end. Confetti and a "done today" count when you tick something off. Undo, keyboard shortcuts, swipe gestures on phones, dark and light themes. It's a web app that works in your phone browser, it's free, and you can try it without signing up.

It's also worth being clear about what it doesn't have: no due dates, no reminders, no recurring tasks, no notes, no subtasks, no native app and no offline mode. If any of those are essential for you, it isn't the right tool, and you should pick something else without guilt.

If the list above sounds like what you've been looking for, give it the seven-day test.
