# Planner vs Routine App vs To-Do List for ADHD *Three categories of app, three different problems. Which one you need depends on whether your day fails at deciding, at seeing, or at doing — and using the wrong one feels like personal failure.* URL: https://orbit.groot-apps.com/guides/planner-vs-routine-app-vs-todo-list/ By Aron de Groot · Published 6 September 2026 · 696-word read In short A to-do list holds things you have not decided about yet. A planner shows where things sit in the day. A routine app runs a fixed sequence with you. If tasks pile up undecided, you need a list. If the day disappears, you need a planner. If you know exactly what to do and still do not do it, you need a routine app — and that is the most commonly misdiagnosed case. Key facts - To-do lists store undecided work; planners position work in time; routine apps execute a fixed sequence. - The most common mistake is using a to-do list for a problem of initiation rather than of memory. - A to-do list that grows faster than it shrinks becomes a source of dread, not a tool. - Recurring tasks in a to-do list are a weak substitute for a routine, because the app does not run them with you. - Most people with ADHD end up needing two of the three, rarely all three. ## Three tools, three jobs | | What it holds | Question it answers | Fails when | |---|---|---|---| | To-do list | Undecided work | What is there to do? | The list grows faster than it shrinks | | Planner | Work placed in time | When does this happen? | The first delay invalidates everything after it | | Routine app | A fixed sequence | How do I get through this? | The sequence is too long or too rigid | The categories are not competitors. They handle different stages of the same work, and the mistake most people make is buying a tool for the stage that was not broken. ## The to-do list A list is a memory prosthesis. Its actual job is to catch a thought before it disappears, so that acting on it becomes possible later. For ADHD it earns its place through capture speed. If getting something into the list takes more than a few seconds, it will not get captured, and an incomplete list is worse than none because you can no longer trust it. Where it fails is that a list has no opinion about what happens next. Everything is equally present, forever, which is why a long list stops producing action and starts producing dread. A list is not a plan and does not become one by getting longer. ## The planner A planner puts work somewhere specific: on a timeline, in a calendar block, in a day. It answers when. For ADHD its main value is making time visible. If you cannot feel duration — see time blindness — a day drawn as a strip with things on it is far more informative than the same day described in words. Where it fails is brittleness. A schedule that assumes accurate time estimates and no interruptions has one point of failure repeated forty times. The standard collapse is to deviate at 09:40 and treat the rest of the day as void, which is why anchors work better than timetables. ## The routine app A routine app holds a sequence you have already decided on and runs it with you: this step now, that step next, this one after. It answers how do I get through this, and it is the category most people skip — because if you know what to do, it does not feel like you need an app to tell you. But knowing and doing are separate operations, and it is the doing that fails. That is the whole subject of executive dysfunction. Where it fails is scope. A routine app is useless for one-off tasks, cannot hold your appointments, and does not care what day it is. Ask it to be a planner and it will disappoint. ## Diagnosing which one you need Think about the last week that went badly, and match the sentence. - "I forgot about it entirely until it was too late." → to-do list, with fast capture. - "I knew about it and never found time. Where did the day go?" → planner. - "I knew exactly what to do, had the time, and still did not do it." → routine app. - "I did it and forgot I did it, so I have no idea whether it is working." → habit tracker, which is a fourth and much narrower category — see tracker versus routine app. Most people match two. Very few match all four, and installing four apps is its own failure mode. ## A workable combination For most adults with ADHD the useful pairing is one fast capture tool plus one routine runner, with a calendar for anything with a fixed time. Capture catches thoughts so they stop consuming working memory. The routine runner handles the two or three sequences — morning, wind-down, deep-work start — that determine whether the day begins and ends properly. The calendar holds appointments, which are the only genuinely time-bound things most days contain. Adding a planner on top helps if time is genuinely invisible to you. Adding a fourth tool almost never does. Orbit is the routine runner in that arrangement. It deliberately does not hold your tasks or your calendar, because doing so would make it another thing to maintain — and maintenance is what gets abandoned first. ## Frequently asked **Do I need a to-do list or a routine app?** A to-do list if the problem is that things fall out of your head before you can act on them. A routine app if the problem is that you know exactly what to do at 7am and still cannot get through it. The second case is far more common than the number of routine apps installed would suggest. **What is the difference between a planner and a to-do list?** A to-do list holds work in no particular time; a planner puts it somewhere specific in the day. The list answers what, the planner answers when. Lists grow without limit, which is why a long list stops feeling actionable — a planner forces the honest question of what actually fits. **Can one app do all three?** Several try. The result is usually good at one and adequate at the others, and every extra function adds configuration you have to maintain. Two focused apps generally beat one that does everything, as long as it is clear which one you open when. ## Sources and further reading - Executive function skills — CHADD - ADHD in adults — overview — CHADD - Time blindness and ADHD — ADDitude ## Orbit builds these routines for you Orbit is an ADHD routine builder for iPhone: templates instead of blank screens, an ambient orb that runs each step with you, and streak freezes so a missed day doesn't undo a month.
