In today’s highly competitive app market, why do some apps stand out, make users love them, and even form habitual use, while others are unknown? This article delves into the key factor behind it – emotional design. By analyzing successful cases such as Duolingo, Phantom Wallet, and Revolut, it reveals how emotional design establishes emotional connections between users and products through delicate animations, humanized feedback, and exquisite visual effects, thereby driving user growth, enhancing user loyalty, and achieving commercial success.
Have you ever wondered why you unconsciously open Duolingo every day, but other language learning apps lie in the depths of your phone gathering dust? Why does Phantom Wallet stand out in the competitive crypto market while most similar products fall short of it? Why does Revolut make users willing to pay for high-end financial services while traditional banking apps keep them away? The answer is not in the amount of functionality or the complexity of the technology, but in an element that is seriously underestimated by most developers: emotional design.
What does a product manager need to do?
In the process of a product from scratch, it is not easy to do a good job in the role of product manager, in addition to the well-known writing requirements, writing requirements, writing requirements, there are many things to do. The product manager is not what you think, but will only ask you for trouble, make a request:

In this day and age, building software has never been easier. We have a variety of APIs, no-code tools, AI models, and all the technical building blocks at your fingertips. Anyone can build a fully functional application and quickly launch new features in a matter of days. The result of this democratization of technology is that it is no longer enough to be “useful”. When the market is full of products with similar features, the real competitive advantage is: How does a user feel when they open your app? Is it smooth, enjoyable, fun, or high-end? Or does it just feel as mediocre as other apps on the market?
Of course, a successful product still requires a combination of factors: a solid business model, good market timing, strong community support, etc. But I am becoming more and more aware that what really distinguishes excellence from excellence is the kind of design that can establish a connection with users, the kind of design that makes people feel attentive, and the kind of design that can convert ordinary users into loyal fans. Netflix co-founder Reed Hastings summed it up nicely: “The product has to be good enough for people to actively talk about it.” “In a world where every product has access to the same technical resources, this is your long-term competitive advantage. Not the code, not the list of features, but how your product leaves the user when they close the app or slide away the screen. This article takes three different types, but all of them are irresistible products, as examples to talk about this unique design secret, part of which is compiled from Tim’s video sharing.
Duolingo’s Emotional Magic: Turning Learning into a Habit
Let me start with Duolingo, a classic example of emotional design. Duolingo didn’t just create another language learning app, they built a product that responds to users in real time and feels truly human. In 2022, they introduced a complete character animation system, including facial expression reactions, lip changes synchronized with audio, and idle animations that appear even when the user is not doing anything, making their characters appear alive even when stationary.
The business impact of these changes is astounding. Duolingo’s data shows that their daily active users more than doubled in two years after the launch of these animation features, from 14.2 million to over 34 million. What’s more, the number of paid subscribers also doubled during the same period. Of course, this growth comes from a combination of factors, such as new languages, curriculum improvements, marketing campaigns, and more. But interestingly, Duolingo’s own team has repeatedly emphasized that character animation is one of the main reasons people stay engaged.
CEO Luis Vonan has noted on multiple occasions that the app’s delightful experience, including these animations, makes it stand out in a market full of boring functional apps. This connection is not accidental. These animations are more than just visual decorations—they serve as vectors for emotional feedback. They create an emotional loop that keeps users engaged. When you answer a question correctly or make a mistake, you get more than just a green checkmark, you feel encouragement, correction, and even cheering and solidarity. These quick responses boost engagement by triggering emotional feedback loops, as elaborated by UX guru Don Norman in his book “Designing for Emotion.”
I delved into Duolingo’s design strategies and found that their success goes far beyond superficial animations. They truly understand the psychological characteristics of the language learning scenario: learning a new language itself is a process full of frustration and self-doubt, and users can easily give up due to slow progress or frequent errors. Traditional language learning applications are often too serious, giving people a sense of “exam” oppression. Duolingo transforms this otherwise anxious experience into a gamified pleasure through emotional design.
Their animation system handles the various emotional points in the learning process very subtly. When users answer the questions correctly, Owl Duo will show a proud expression, as if they are genuinely happy about your progress; When you answer incorrectly, it does not show disappointment, but rather a gentle encouragement to feel that it is okay to make mistakes and that the important thing is to keep trying. This emotional feedback design subtly redefines what it means to be “wrong,” transforming it from “failure” to “learning opportunity.” What’s even more interesting is that the animation becomes more enthusiastic and celebratory as users complete learning tasks for multiple days in a row, reinforcing the positive feedback of the behavior of “sticking.”
From a neuroscience perspective, this design strategy is very clever. Each positive emotional feedback stimulates the brain to release dopamine, a neurochemical response that reinforces the user’s motivation to continue using the app. What’s more, this emotional experience builds positive emotional memories in the user’s brain, making them think of learning a language not with boredom and difficulty, but with a sense of accomplishment and fun. This psychological shift is the fundamental reason why Duolingo has been able to maintain such high user engagement.
This case inspired me that if your product relies on repetitive user behaviors like check-ins, journaling, or habit tracking, you should add micro-interactions that provide immediate emotional feedback. A subtle bounce, halo or flicker, small details that can make the confirmation moment feel more rewarding. At the same time, celebrate small successes. Reinforcing engagement doesn’t require a huge state of success, but they should feel intentional. If you have a mascot like Duolingo, use it to show expressions and encourage users, because emotions are contagious. This could be a small nod, a smile, or an animated reaction that makes the experience feel more human.
A deeper insight is that you need to deeply understand the psychological state and emotional needs of users when using your product. When do users need encouragement the most? When is it easy to get frustrated? When do you need a sense of accomplishment reinforcement? Only by truly understanding these emotional nodes can you design an emotional experience as effective as Duolingo. Finally, if you want to give users a momentum feel, include beautiful progress animations. This could be anything like using an action to show a combo record, or showing different levels, the number of journals completed, anything that gives the feeling of building something over time. The goal here is to make feedback feel human and not just functional, as this emotional dimension can quietly create a powerful connection between the user and your product. Even very simple things, when done right, can make the experience feel more alive and worth coming back to.
Phantom’s Trust Rebuilding: Sowing Confidence in Doubt
Duolingo builds habits by designing people to feel good about using the app. That good feeling is one of the main reasons why users keep coming back. But what happens when your users are not trying to build a habit, but to overcome doubt? This is one of the main challenges facing cryptocurrency applications and one that Phantom has set out to solve through emotional design and animation.
Let’s start with a harsh reality: the user experience in cryptocurrencies is generally terrible. Phantom knows this. So when they launched a full rebrand in mid-2023, they didn’t just change the logo, they overhauled everything and introduced animation to change people’s perceptions. They added animations to the ghost mascot, incorporated fun animations into the wallet creation process, and put a lot of effort into making every interaction feel fun and approachable. The goal here is clear: to make crypto feel less scary and more human.
Apparently, this strategy worked. Today, Phantom is one of the most widely used wallets in the crypto space and recently became the second-largest app in the US app store tools category, surpassing apps like WhatsApp and Instagram. Just like Duolingo, Phantom’s growth has benefited from market momentum and smart business execution. But what really makes them stand out is that they’re design-oriented from the start.
Their CEO, Brandon Milman, is very clear about this. This is not just another wallet. From day one, the team focused on refinement, craftsmanship, and building something that really felt good to use. In his own words: “Refinement is important. We are a design-oriented company that takes the time to create sophisticated products. “This mindset pays off because Phantom focuses on consumers when most wallets are developers built for other developers. Their goal is to bring the next billion people into Web3, which means investing in clear, emotional UI and animations.
I draw from Phantom’s success a few important principles when designing in intimidating, complex, or high-risk areas such as finance, cryptocurrency, health, or insurance. First, refinement builds trust. Think of visual details, movements, and transitions as core product features, not decorations. Every tiny interaction is a signal of trust. Second, stay approachable. Friendly visuals and warm, fun details make heavy topics feel a little lighter, which goes a long way in building confidence. Third, it is designed for ordinary people, not professionals. Don’t assume users know the rules and design processes that make sense for everyday people, especially if you’re reaching people other than early adopters. In the end, performance matters, but what really stays in people’s minds is how the product feels when someone clicks, swipes, or waits. Giving users smooth feedback increases their confidence in your product.
Revolut’s Luxury Code: How to Sell High-End by Design
We’ve seen how characters and pleasure create trust, but trust isn’t everyone’s ultimate goal. Let’s explore how emotional design and motion can be used to sell luxury in a more profitable way, which brings us to the case of Revolut.
Revolut has been investing in design and animation for years. But what’s particularly interesting is how their design upgrades are fully synchronized with their push into the premium segment. As they move upstream, their visual language becomes more refined, and it’s clear that they do it intentionally, aligning the product feel with the direction they want their business to take.
Take the first user experience, for example. They won’t get you stuck in a boring sign-up process. Instead, you get rich visuals, super smooth transitions that immediately feel like you’re stepping into some kind of high-end experience. I mean, even their charts have been upgraded. You don’t just look at spending data, you can feel it. You drag it with your finger, and the chart responds with a soft halo, transforming the numbers into something more tactile and tactile
The same goes for their cards. You don’t just see static images, you get full 3D moments. Cards flip, rotate, catch light. It’s concise, intentional, and honestly satisfying. These small details, like subtle animations in security processes or onboarding, provide that sense of trust without being deliberate. None of these design details will yell at you, but together they create a more high-end feel.
In the realm of fintech, trust directly influences how much users spend, and this sophistication translates directly into income. This is an important inspiration for me: to master the first impression. Take the time to refine your onboarding guidance, refine your welcome moments, and convey quality, trust, and care immediately. Add subtle moments of pleasure, such as animations, fade effects, hover effects, or gestures. Build emotion and make touchpoints feel intentional. Make interactions feel dynamic. Haptic charts, responsive feedback, or animated cards that transform essential functionality into something feeling-uplifting and engaging.
The business logic of emotional design
By analyzing these three success stories, I found that emotional design is not a decoration of the product, but the core engine that drives business success. Each case proves a key insight: in an era of functional convergence, emotional differentiation becomes the most powerful competitive weapon.
Duolingo doubled its daily active users with character animations, Phantom gained leadership in the competitive crypto wallet market with its sophisticated design, and Revolut successfully expanded into the upstream market with its high-end visual experience. These successes all have one thing in common: they win not by adding more features, but by making users feel better when using the product.
I think this shift reflects a fundamental change in user expectations. Today’s users, especially digital natives, are accustomed to high-quality digital experiences. They are no longer satisfied with “just usable” products, they expect products to understand and respond to their emotional needs. That’s why companies that invest in emotional design are able to build stronger user loyalty, higher conversion rates, and better user retention.
Let me dive into how emotional design works on a business level. The first is a significant reduction in user acquisition costs. When a product has strong emotional appeal, users are more willing to actively share and recommend, and the cost of this word-of-mouth communication is much lower than that of traditional paid customer acquisition channels. Duolingo’s virality is largely due to its fun learning experience, which makes users willing to share their learning results on social media. This spontaneous branding saves the company a lot of marketing budget.
The second is the significant increase in user lifetime value. Emotional design creates not only a one-time pleasant experience, but also a long-term emotional dependence. Once users establish an emotional connection with the product, their churn rate will be significantly reduced, the frequency of use will be significantly higher, and the willingness to pay will increase. This deep engagement directly translates into higher user lifetime value. In Duolingo’s case, the doubling of paid subscription rates is the best proof of this.
The third is the improvement of brand premium ability. Emotional design elevates products from purely functional tools to emotional carriers, a shift that allows brands to charge higher prices. Revolut has successfully expanded into the premium segment with a sophisticated design experience, and users are willing to pay a premium for a better experience, which directly boosts the company’s profit margins. Similarly, Apple’s success over the years is a testament to the effectiveness of its design-driven premium strategy.
The deeper business logic is that emotional design changes the dimension of competition. Traditional product competition mainly focuses on functional comparison and price competition, which often leads to homogenization and reduced profit margins. Emotional design opens up a new competitive dimension, allowing companies to jump out of the red ocean of features and prices and establish a unique competitive advantage in the blue ocean of emotional experience.
From the perspective of behavioral economics, affective design taps into important psychological mechanisms in the human decision-making process. Research shows that people’s purchasing decisions are often driven by emotions before using reason to justify that decision. Good emotional design can establish a positive emotional connection on the subconscious level of users, influencing their decision-making process and making them more inclined to choose and stick to your product.
I also observed that the mechanism of action of emotional design is also different in different business models. For the B2C subscription model, emotional design primarily creates value by increasing user engagement and reducing churn rates. For the one-time purchase model, it drives growth more through brand premium and word-of-mouth communication; For the platform model, emotional design creates value by enhancing user engagement and network effects. Understanding these differences is crucial for developing targeted and emotional design strategies.
What’s more, emotional design creates a competitive advantage that is difficult to replicate. Anyone can replicate the features, but it’s hard to replicate the feeling. When users connect emotionally with your product, they are not only more likely to continue using it, but they will also become your brand ambassadors, actively recommending your product to others. This organic word-of-mouth spread is often more effective than any paid marketing.
From a business perspective, the ROI of emotional design often exceeds expectations. While more time and resources need to be invested in polishing the details upfront, in the long run, this investment will pay off handsomely through higher user satisfaction, lower customer acquisition costs, and stronger brand loyalty. Especially in today’s prevalence of subscription models, a small increase in user retention can lead to significant revenue growth. From my observation, companies that value emotional design early on often reap exponential business returns later on, because once the emotional connection is established, it becomes the company’s most valuable intangible asset.
How to apply emotional design in your own products
Once you understand the importance of emotional design, the key question is how to actually apply these principles in your own products. I’ve summarized several strategies that you can start implementing right away.
The first is the power of micro-interaction. Don’t underestimate the impact of small details. A subtle feedback when a button is pressed, a well-designed loading animation, and a celebratory effect after a successful operation are all seemingly insignificant elements that can significantly enhance the user experience. The key is to make every interaction feel responsive and intentional. Users should feel that the product is listening and responding to their every move.
The second is to establish an emotional feedback loop. Just like in the case of Duolingo, you need to ensure that users receive immediate and meaningful feedback on their behavior. This feedback should not be just functional (like “operation completed”) but emotional (like “Awesome!”) You’re one step closer to your goal”). This emotional feedback makes users feel validated, encouraged, and more willing to continue using your product.
The third is to pay attention to the visualization of progress. People naturally like to see their progress, whether it’s learning a new skill, completing a task, or reaching a goal. With beautiful progress animations, achievement systems, or milestone celebrations, you can make users feel a sense of growth and accomplishment. This feeling reinforces their motivation to use it, making them more willing to stick with it for a long time.
Finally, maintain brand consistency. Emotional design is not a patchwork of fragmented animation effects, but should be part of the overall brand experience. From visual style to interaction, from copywriting tone to animation pacing, all elements should serve a unified emotional goal. Only in this way can a cohesive and powerful user experience be created.
Of course, implementing emotional design also requires balance. Excessive animation or overly fancy effects can backfire, leaving users feeling irritated or distracted. The key is to find that sweet spot: attractive enough without interfering with functionality, personal enough but not contrived. This requires extensive testing, iteration, and user feedback for continuous optimization.
I believe that with the intensification of market competition and the increase of user expectations, emotional design will change from “icing on the cake” to “necessity”. Those products that can touch the hearts of users in addition to function will dominate the future market competition. It’s time to start investing in this capability, because as these success stories demonstrate, emotional connection becomes the strongest moat when technology is no longer a barrier.
Written at the end: The future of emotional design
Looking back on the entire analysis process, I became increasingly convinced that we were at an important turning point in product design. The democratization of technology has made it easier to create features, but it also means that pure functional innovation will become increasingly difficult to create a lasting competitive advantage. In this context, emotional design is no longer a luxury but a necessity for survival.
From Duolingo’s character animations to Phantom’s trust rebuilding, from Revolut’s luxury experience to countless other success stories, we’re seeing the same trend: the most successful products are those that touch the user’s emotions beyond their functionality. They don’t just solve problems, they create feelings; It’s not just about providing services, it’s about building relationships.
I predict that in the coming years, we will see explosive applications of emotional design in more areas. Not only consumer applications, but enterprise software will also begin to value the emotional experience of users, as even users of B2B products are people with emotional needs. Traditionally function-oriented fields such as finance, healthcare, education, and industrial software will all usher in a wave of emotional design.
For product entrepreneurs and designers, now is the perfect time to invest in emotional design capabilities. Don’t wait until your competitors have already established an advantage through emotional design before jumping into action. From now on, incorporate emotional design at the core of your product strategy, develop relevant competencies, and build a design culture. Remember, in a world where functions are becoming increasingly homogeneous, emotional connection will be the most powerful weapon of differentiation.
Finally, I would like to emphasize that emotional design does not mean flashy or overly decorated. Truly excellent emotional design is restrained, purposeful, and serves the real needs of users. It does not exist to show off skills, but to make products better serve humanity. When we can meet emotional needs while meeting functional needs, we create not just products, but experiences that truly improve people’s lives
