Task apps, GTD, and ADHD
Most people arrive at a page like this with a graveyard behind them: two or three apps, a bullet journal, a whiteboard, and a system that worked beautifully for eleven days. This page is about task-manager design, not medical advice — what makes a system survivable when attention and working memory are unreliable, and what that asks of the software.
The system asked for too much.
When a productivity system gets abandoned, the usual reading is that the person lacked discipline. The more accurate reading is that the system was charging more than it paid out. Every system has an upkeep cost — tags to maintain, priorities to re-score, a planning ritual every morning, a hierarchy to keep tidy. When the cost lands up front and the benefit arrives later, the whole thing is fragile for everyone. It is the first thing to go when a week gets loud.
The second cost is quieter. After a lapse, the list reads as a record of what you didn’t do: forty overdue items in red, each one an accusation. Re-opening it is unpleasant enough that you don’t, and the gap widens. Plenty of systems are pleasant to start and punishing to return to. That is a flaw in the design, not in you.
What makes a system survivable
Whatever tool you use — paper, plain text, an app — these four properties tend to separate the systems that last from the ones in the graveyard.
-
Capture faster than the thought evaporates
An idea has a shelf life measured in seconds. If writing it down takes unlocking, launching, navigating, and choosing a project first, it doesn’t get written down — and a system that isn’t fed stops being worth opening.
-
One next step, not the whole mountain
A project shown in full is a wall. Ask for the single physical action rather than the state of the whole kitchen, and keep everything else out of sight while you answer.
-
External memory, because held memory runs out
Even under careful laboratory conditions, estimates of how much a person can actively hold in mind land around four items (Cowan, 2001). Nobody has enough. The fix is to stop using memory for storage.
-
Structure that survives a bad week
You will lapse. Assume it, and judge a system by how cheap it is to re-enter. If picking it back up costs an evening of cleanup and a wall of red, the lapse becomes permanent.
Where Mindwtr lines up
Mindwtr wasn’t designed for ADHD, and it would be dishonest to claim otherwise. It was built to run GTD faithfully — but several of the properties above happen to be the ones the method insists on, so they’re in the app by inheritance.
-
Capture in one gesture
A home-screen widget on Android and iOS, a lock-screen widget, an Android Quick Settings tile, and a global hotkey on the desktop. Each opens straight into a text field. Everything lands in one Inbox; sorting is a separate job for later.
-
Sequential projects show one action
Put a project in sequential mode and only the first open task reaches your Focus and Next Actions lists. The remaining steps stay recorded in the project, marked Later in sequence, so nothing is lost and nothing is in the way.
-
Contexts cut the list down
Contexts filter by what you have right now — at a computer, out running errands, phone in hand. Fewer visible options is the point; deciding is the expensive part.
-
Reminders that fire on your device
Notifications are scheduled locally by the app. No account, no server, and no network needed — they work on a plane, in a basement, and on a phone that hasn’t seen wifi all day.
-
A Weekly Review built for re-entry
The guided Weekly Review walks through your lists and asks what’s still real. It is the designed way back in after a bad fortnight: a tidy-up pass rather than a reckoning.
-
Free, so a lapse can’t cost you the system
Completely free and open source under AGPL-3.0, with no account and no subscription. Nobody locks your list behind a renewal you forgot, and your tasks sit in a local SQLite file you can copy like any other file.
What an app can’t do.
No software makes executive function reliable. A task manager can lower the cost of a handful of specific actions — writing something down, finding the next step, remembering at the right moment. It cannot supply the start, and anyone promising otherwise is selling something.
So take the parts that help and leave the rest. On some days an index card with three lines on it will beat any app ever written, and that is a good outcome. You also don’t need the whole method: an Inbox you trust and a list of genuine next actions is already a working system, and the rest of GTD can wait indefinitely. And nothing on this page is advice about ADHD itself — that’s a conversation for people who know your situation.
