Duolingo is a popular language-learning app that uses fun, interactive methods to help users learn new languages. Known for its playful design and intuitive user interface, Duolingo features vibrant icons and a gamified approach to keep users engaged.

In this case study, I’ll showcase how I transformed Duolingo’s original icons into a Halloween-themed set. While some icons were enhanced with spooky elements, others were completely redesigned to fit the Halloween spirit. The goal was to maintain the app’s fun, educational feel while adding a festive, magical twist.💫

Hi Benginur!

The icon set is playful and colorful, which aligns really well with the product’s tone. One observation is that some icons are quite detailed while others are more minimalistic, creating a slight inconsistency—something you could consider refining. I also love the toggle button concept! You could simplify it further by using just the eye symbol, without the square background, for a cleaner look.

Good luck!

Hi Yuliia! Thank you for the kind feedback! I’m happy the colors and playfulness fit the product’s vibe. Great point about the icons , I’ll work on making them more consistent. And I love the idea for the toggle button; I’ll give that a try. Thanks again! 😊

Great presentation! I love your prototype, and you’ve successfully maintained Duolingo’s brand identity with your icon set. Very creative—awesome job!

Thank you! So glad you liked it.

Amazing project! I really liked the presentation of your design, keep up the good work!

Thanks a lot, Stefan!

Crisp and professional!

Thanks, Maham! Glad to hear that!

Congratulations, your presentation was amazing!

The only thing I disliked was the toggle with the eye because it takes out some clarity of the function of the component. The rest are super well integrated. Good job!

Thank you! Glad you liked the presentation. Appreciate the feedback on the toggle.I'll work on it! 😊

Wow, what an innovative way to present the icons! They are a good blend of the Halloween theme. I know how much effort is required to design these icons.

Fantastic project. Thank you

Thank you Kunnal! I’m glad to hear you appreciated it.

Hi Benginur!

Your DuoLingo Icon set is a great addition to the DuoLingo app, bringing playfulness during spooky season! Your use of color within these icons truly brings these icons to life while staying in DuoLingo's color scheme, creating a seamless logo integration experience.

My only critique of your project is about the functionality of icons. For some users, connecting the imagery of some of your icons to their functional use will be a challenge. For example, the broomstick icon replaces the dumbbell and the cauldron replaces the feed. Although you explained these icons which brought great insight into the imagery, it may be difficult for users to understand what menu the icon takes them to without clicking on it, especially for newer users just beginning their Duolingo journey.

Other than that, you created a beautiful presentation that brought clarity to your process and a set of super cute, portfolio-worthy icons! Great job!

Hi Catherine! Thank you so much for the thoughtful feedback. I'm glad you liked the playful touches and colors.I totally see your point about icon clarity for new users—I'll keep that in mind for future designs. Thanks again, really appreciate your insights!

Duolingo does such a good job allowing users to have fun learning new languages. To elevate it without diminishing the learning with your icons and brand updates is adorable and approachable.

You're attention to detail is noticeable. You match the users emotions well through your icons and even in dark mode, so cool with the green status bar.

Good luck and great work!

Thank you so much for the thoughtful feedback, Candace!

Love the presentation! The whole case, OMG 🤩

Very deep and thoughtful work. Horray!

Thanks a lot, Bohdan!
