# Habit Stacking for ADHD: Examples and How to Make It Work *Habit stacking attaches a new habit to one you already do. Why it helps ADHD, why it often fails, and how to choose reliable anchors — with 12 examples.* URL: https://orbit.groot-apps.com/guides/habit-stacking-adhd/ By Aron de Groot · Published 10 September 2026 · 4-minute read In short Habit stacking means attaching a new behaviour to one you already do reliably — "after I pour my coffee, I take my medication" — so the old habit becomes the cue. It builds on BJ Fogg's Tiny Habits and was popularised by James Clear. With ADHD it helps because it replaces remembering with a trigger, but it fails if the anchor is not truly reliable, the new habit is too big, or the cue is invisible. Choose physical, daily anchors and tiny first steps. Key facts - Habit stacking uses an existing habit as the cue for a new one: "After I [anchor], I will [new habit]." - It builds on BJ Fogg's "anchor moment" in Tiny Habits and was popularised by James Clear's Atomic Habits. - For ADHD, its value is replacing memory with a trigger that happens anyway. - It fails when the anchor is not truly daily, the new habit is too big, or the link is not visible. - Physical anchors (putting the kettle on, sitting in the car) work better than mental ones ("when I feel ready"). ## What habit stacking is Habit stacking is attaching a new habit to one you already do, so the existing habit becomes the reminder. The formula is: After I [current habit], I will [new habit]. "After I pour my morning coffee, I take my medication." "After I sit down at my desk, I write my first task." The idea comes from BJ Fogg's Tiny Habits method, where the existing habit is called the anchor moment, and was popularised as "habit stacking" by James Clear in Atomic Habits. It is closely related to implementation intentions — deciding in advance exactly when and where you will act — which Peter Gollwitzer's research found makes follow-through substantially more likely. ## Why it helps with ADHD The hardest part of a new habit with ADHD is usually not doing it; it is remembering to do it at the right moment. Memory is exactly what ADHD makes unreliable, and "I'll do it in the morning" is a plan that relies on remembering. Habit stacking swaps memory for a trigger. You do not have to remember to take your medication; you only have to pour your coffee, which you were going to do anyway. The anchor carries the new habit along with it. ## Why it often fails with ADHD Plenty of people with ADHD try habit stacking and find it does not stick. It usually fails in one of four ways: 1. The anchor is not actually reliable. "After breakfast" only works if you eat breakfast. With ADHD, many assumed routines are more irregular than they seem. The anchor has to be something that happens every day, without exception. 2. The anchor is mental, not physical. "When I feel ready" or "when I have a moment" are not anchors. Physical events are: putting the kettle on, unlocking the front door, sitting in the driver's seat, switching off the shower. 3. The new habit is too big. If the stacked habit takes twenty minutes, the anchor becomes something you start avoiding. BJ Fogg's rule is to make the new behaviour tiny — seconds, not minutes — and grow it later. 4. The link is invisible. Knowing the rule is not the same as seeing it at the moment. Put the new habit's object at the anchor: medication next to the kettle, the vitamin next to the toothbrush, the notebook on the keyboard. ## How to choose good anchors A good anchor is: - daily — it happens every day, including bad ones; - physical — a specific action or place, not a feeling; - specific — "when the kettle clicks off", not "in the morning"; - followed by a pause — there is a natural moment to add something. Some of the most reliable anchors people have: waking up and turning off the alarm, the first drink of the day, using the toilet, brushing teeth, sitting down at a desk, getting in the car, arriving home and unlocking the door, the kettle boiling. ## Twelve examples | After I… | I will… | |---|---| | Turn off my alarm | Drink the glass of water on the bedside table | | Pour my first coffee | Take my medication (kept next to the machine) | | Brush my teeth in the morning | Apply sunscreen | | Switch off the shower | Put on moisturiser | | Sit down at my desk | Write today's first task on a sticky note | | Get in the car | Put my phone in the glovebox | | Finish lunch | Take a five-minute walk | | Close my laptop for the day | Clear the desk for two minutes | | Walk in the front door | Put my keys on the launch pad | | Load the dishwasher | Wipe the counter | | Brush my teeth at night | Lay out tomorrow's clothes | | Get into bed | Plug my phone in across the room | ## From stacks to routines Stacking two habits is the first step towards a routine. Stack three or four in a row and you have one: kettle → medication → breakfast → clothes. That is also where stacks start to wobble, because each link depends on remembering the next. At that point, it helps to write the sequence down or let an app hold it — a routine is really a stack with the order stored outside your head. How to build a routine with ADHD covers the next step. ## How long it takes Expect weeks, not days. In the best-known study of habit formation, by Phillippa Lally and colleagues, simple daily behaviours took a median of 66 days to feel automatic, with a very wide range. Missing a day did not significantly derail the process — which is worth remembering the first time a stack slips. ## Where Orbit fits A routine in Orbit is a habit stack with the order written down for you. Build a short routine that starts with your anchor — "Coffee", "Medication", "Breakfast" — and start it when the anchor happens, with one tap or by asking Siri. The current step stays on your Lock Screen, so the next link in the stack is always visible. ## Frequently asked **What is habit stacking?** Habit stacking is attaching a new habit to one you already do reliably, using the formula "After I [current habit], I will [new habit]". The existing habit acts as the reminder. The idea comes from BJ Fogg's Tiny Habits method and was popularised by James Clear in Atomic Habits. **Does habit stacking work for ADHD?** It can work well, because it replaces remembering with a trigger that happens anyway — and remembering is what ADHD makes unreliable. It fails when the anchor is not truly daily, when the new habit is too big to do immediately, or when the link between them is not visible at the moment it matters. **What are good habit stacking examples?** After I pour my morning coffee, I take my medication. After I turn off the shower, I put on moisturiser. After I sit down at my desk, I write my first task. After I close my laptop, I tidy the desk for two minutes. After I brush my teeth at night, I lay out tomorrow's clothes. ## Sources and further reading - Habit stacking — James Clear - Tiny Habits — BJ Fogg - Implementation intentions: strong effects of simple plans (Gollwitzer, 1999) — American Psychologist - How to form a habit (on Lally et al., 2010) — British Psychological Society ## 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.
