Companies get you addicted to their products by building a habit loop: a trigger starts it, an easy action follows, a reward pays off and your own time or data keeps you invested. This article walks through 15 ways brands do it, using Nir Eyal’s Hook Model, and updates the examples with Meta, Duolingo and Clubhouse for 2026.
| Hook Model step | What it does | Example |
|---|---|---|
| Trigger | Starts the habit | A push notification, an ad or a feeling of boredom |
| Action | The simplest behaviour in anticipation of a reward | Opening the app or tapping buy |
| Variable Reward | Pays off, but not always the same way | Likes, a new feed item, a streak |
| Investment | Makes the next loop more likely | Photos, playlists, friends, a 100-day streak |
1. Companies design a habit zone around the product
The first step is to make the product part of the customer’s routine. Nir Eyal, author of Hooked: How to Build Habit-Forming Products, argues that many everyday decisions are made on autopilot because they worked yesterday. The brain treats a choice that paid off before as a safe bet today, so a company wins when its product becomes that automatic choice.
The big question for any brand is how to get into that zone.
2. Behaviour needs almost no thought
Eyal describes habits as behaviours done with little or no conscious thought. Think about where you go when you search for something. For most Aluxers it is Google. When you want a video, it is YouTube. You rarely weigh alternatives, and that is the point: once a habit forms, switching feels like effort.
Fortunately, we rarely change our formula on Alux, so don’t forget to subscribe.
3. Habits are built on repetition
At Alux, we grew by publishing videos and articles daily and at the same time. Subscribers learned when to expect us and what they would get. That repetitive rhythm is a habit loop in its own right, and it is how our channel grew steadily.
Every habit-forming brand picks its own angle. Ours was timely, daily content you can learn and grow from.

4. The Hook Model: four steps that repeat
Eyal calls his habit-building process the Hook Model. It has four parts: Trigger, Action, Variable Reward and Investment. Each pass through the loop makes the next one more likely.
You can listen to his book on Audible, which covers practical ways to build user habits and looks at how apps such as Twitter, Instagram and Pinterest use them. Claim your free listen at alux.com/freebook.
5. Trigger: what starts the loop
Every habit needs a starting cue. External triggers come in four kinds:
- Paid triggers: advertisements.
- Earned triggers: press coverage, viral moments and other attention you did not buy.
- Relationship triggers: word of mouth from people you know.
- Owned triggers: emails, newsletters and notifications you signed up for.
Over time the strongest trigger is internal. When a product becomes tied to a feeling, such as boredom, loneliness or curiosity, you reach for it without any outside prompt. That is what every consumer app is trying to build.
6. Action: make the next step easy
The next step is to get the trigger to produce a reaction. Action depends on motivation, ability and simplicity. A brand’s identity supplies the motivation. Nike’s “Just Do It” is the textbook example.
Ability and simplicity are about friction. If buying takes five screens, most customers leave before the reward. This is why one-tap checkout and saved payment details matter so much to retailers.
7. Reward: the part that keeps you coming back
Rewards come in three kinds, and the best products combine them:
Rewards of the Tribe are social: likes, comments, followers and the sense of belonging. Duolingo’s weekly leagues, where you compete with up to 30 other learners, are a clear example.
Rewards of the Hunt are the search for more. You open an app to check one thing, and an hour later you are still scrolling. The uncertainty about what comes next is what pulls you on.
Rewards of the Self are the satisfaction of progress and mastery. A streak counter works here: Duolingo counts every completed lesson toward a daily streak and lets you keep streaks going with up to five friends.
8. Investment: why leaving feels expensive
The more time, effort and data you put into a product, the harder it is to walk away. Your photo history, your playlists, your saved passwords and your streak are all investments.
That is why you keep an old email account you never use. You never know when you might want to re-read something from 2005. We depend on things we have put effort into, a lot like relationships.
9. Habit-forming products can improve lives
Before thinking negatively about all this, consider Eyal’s own argument. In a podcast interview, he said the aim is for products that improve the quality of their users’ lives. People can get hooked on harmful things, but they can also build good habits around learning, exercise and saving.
When asked whether companies have a moral obligation to offer products that bring value, his answer was that it is also a business imperative. Customers who feel helped stay longer.
10. The man behind the book: Nir Eyal
Nir Eyal is an Israeli-born American author, lecturer and investor. Hooked came out in 2014 and became a bestseller. His second book, Indistractable: How to Control Your Attention and Choose Your Life, followed in September 2019 and flipped the question: how to protect yourself from products built to hold your attention. His third book, Beyond Belief, was published in March 2026 and reached the New York Times bestseller list.
On his own site he has analysed Slack, Fortnite, Amazon’s Echo, Tinder and The Bible App through the Hook Model, and he wrote on Clubhouse when it was the hot new app. Clubhouse is a useful case study: it reached a reported valuation of about $4 billion in 2021, then cut its staff by half in April 2023. A strong launch trigger did not turn into a lasting habit. Watch our video on it:
11. How to build a habit-forming product in 5 steps
A company needs to answer five questions to turn a one-off buyer into a repeat customer:
- What internal trigger will the product attach itself to?
- What external trigger will it use: advertising, rewards, sponsorships?
- What is the simplest way to get the buyer to act and receive a reward?
- Will the reward satisfy a need but still leave room to come back for more?
- If not, what can be added to bring the customer back?
Eyal’s summary is that companies that form strong user habits enjoy lasting benefits to their bottom line.
12. Companies also use mental shortcuts
Many tricks sit alongside the Hook Model. One is the scarcity effect: “Only 5 left” or “While stocks last”. A scarcity message works as a cue to act now, whether or not the stock level is that low.
Exclusivity works the same way. Clubhouse’s invite-only launch made people want in, as it was hard to get.
13. Examples of highly habit-forming products
The biggest example is Meta’s family of apps. Meta reported 3.60 billion daily active people across its apps in June 2026, up 3% on a year earlier. In July 2026, it said Instagram had reached 2 billion daily users and Threads more than 500 million monthly users.
Duolingo is a newer case. It turns language learning into a daily game with streaks, friend streaks and weekly leagues, and it has added chess lessons (April 2025) and AI conversation features. Apple is a different model: by releasing new devices that work best with its other products, it builds an ecosystem that makes each next purchase feel natural. That last point is our reading of the strategy, not a company claim.
14. The first steps to building customer loyalty
To get customers to keep buying, do the unglamorous work first.
- Offer excellent customer service.
- Choose the right channel and time to communicate. A message at 1 in the morning is not an option.
- Reward loyal customers, for example with a buy 9 get 1 free offer.
- Ask for feedback and act on it.
- Give customers a reason to come to you first.
15. Do not sit back and wait for it to happen
Even brilliant ideas have failed because of zero follow through. You cannot blow hot and cold on getting your product out there. Even when things go well, keep improving, keep learning and keep watching what similar services are doing.
Bill Gates is widely credited with saying that your most unhappy customers are your greatest source of learning. A brand that listens to complaints keeps its habit loop healthy.

FAQ
How do companies get you addicted to their products?
Most use some version of the Hook Model: a trigger starts the habit, an easy action follows, a variable reward pays off and your own investment of time or data makes you stay. Repetition turns that loop into an automatic habit.
What is the Hook Model?
The Hook Model is a four-step habit framework by Nir Eyal, published in his 2014 book Hooked. The four steps are Trigger, Action, Variable Reward and Investment.
What are the three types of variable reward?
Eyal names rewards of the Tribe (social approval), rewards of the Hunt (the search for resources or information) and rewards of the Self (mastery and completion).
Is a habit-forming product always bad?
No. The same mechanics that keep you scrolling also keep you practising a language or saving money. The difference is whether the habit improves your life.
Why are some apps so hard to put down?
They combine all four hook steps. Meta’s apps reached 3.60 billion daily active people in June 2026, and streak and league features make apps like Duolingo hard to drop.
How can I avoid getting hooked?
Notice your internal triggers, such as boredom or stress, and turn off optional notifications. Eyal’s book Indistractable is built around managing attention.
How we put this list together
We kept the original 15-step structure built on the Hook Model and checked each reference against company results and published biographies. Where an example is our own reading of a company’s strategy, we say so.
