If you're trying to build the next big app, you need user engagement. This book lays down a model building engagement by having users constantly return to your app. In the beginning this is prompted, but eventually it'll become instinct. This is how viral loops are formed.

It lays out the "Hook Model", a basic framework of the 4 key stages of each loop:

1. Trigger: How does the loop initiate? In the beginning this may be through external triggers (such as an email, notification, icon badge, etc) but through successive loops the user eventually creates internal triggers where a particular thought or emotion will send them back to your product.

2. Action: Once the user is aware they need to use your product (through the trigger), what it the simplest action they can perform to get some kind of reward. For example a Facebook "Like".

3. Variable reward: How are they rewarded for this behavior? This could be social validation (e.g. "my friends approve!"), collection of material resources (e.g. add a photo to a collection) or personal gratification (e.g. inbox zero). The "variable" part is important - rewards should not always be predictable, encouraging users to repeat the cycle.

4. Investment: Finally, the user needs to put something back in to increase the chance of repeating the loop. This could be content (e.g. a book in your Kindle), user entered data (e.g. profile information or linked accounts), reputation (e.g. something to gain a 5 star seller review), or a learned skill (e.g. I'm now really good at this software program). The investment also sets up the trigger to for the next cycle of the loop.

This book is a really easy read. I wanted something that would get to the crux of the problem and set out a practical framework of how to apply it with examples, without being overly verbose on history and research. It delivered.

I just finished Hooked last night and if you're looking to learn how to actually design for behavioral change, this is a great resource. If you're in the behavioral sciences field you know how difficult it is to find help in actually applying these sciences to business, particularly innovation. Nir explains how to design for habit formation in layman's terms and at the back of each chapter he actually coaches you on immediately applying what you learned to your own specific project - which I thankfully did. These activities were the best way to take theory to direct application. Nicely done.

As a designer, I'm always interested in user's behavior and motivation. This book provides insights for both in a way that's well structured (hook model as a framework).

I also appreciate the real world examples and stories that show the concepts discussed in action.

This book already changed my design approach and thinking and I'm sure that I'll be using this book as a reference as I do my work.

It is not known how many products which really have the global population "hooked" today had their founders initially think in a structured manner about forming those hooks. But now that one looks at these products from the lens of the Hooked framework, a common pattern is apparent.

And this is what impressed me about the book. It brings structure to a mostly unstructured knowledge base. Many who use these products can list out some of the ways in which user engagement loops have been constructed. But to think about such mechanisms from a common framework requires finding patterns and validating them.

Further, the framework is not just useful for post-facto analysis but also for designing new products. Since this is a generic framework, it cannot list out specifics - user motivations, psychology - for all possible problem domains. But it can help arrive quickly at how to approach the design for the problem domain you are attacking.

I am glad that Nir has also added a chapter on ethical considerations while aiming to build habit forming products. This chapter could easily have been skipped, but I commend the author for giving the topic due importance.

The last chapter gives practical steps which can be taken by existing as well as yet not designed products to construct en effective engagement loop. It would have been good to see a detailed example of thinking about a new product from grounds up and follow the steps proposed. Nir does cover example of an existing app but I felt that it did not fully cover the decision making process to arrive at the final product design.

Will recommend to all product managers and designers looking for insights into making their consumer product more engaging.

"Hooked" presents a simple, yet very useful model to channel your thoughts when building a product you want to get in the hands of millions. It's quick to read (only 140 pages), to-the-point and made a world of difference to our concept&design challenges. We used it a lot to model the behavior of our users and figure out specific areas we missed and needed to focus on in order to get engagement.

Another great value of the book is the in-depth analysis of the hooks we are subject to every day (in Twitter, Facebook, Pinterest, Instagram etc). As you go around the everyday loop you know so well from the user perspective, you see in a structured way the other side of the coin. The side of the people who know how to design behavior patterns and make others tick.

I closed 'Hooked' with a much better understanding of social&scalable products and a lot of interesting ideas for what our team is building. These came from the numerous examples and case studies, as well as the structured questions you can answer at the end of each chapter.

If you'd like to learn about habits and how they are built&changed in general, I'd recommend 'The Power of Habit' book by Charles Duhigg. If you want to understand how habits are formed in the world of technology, startups and software and mobile products, "Hooked" is the book for you. It's built on the same solid research base, yet much closer to practice and much more relevant to today's tech world.

Thank you Nir Eyal for this amazing book!
