I gamified the user experience to solve retention challenges with two key features. First, I designed a 'Tree Growing' interface where daily check-ins visualize progress. Second, for the referral system, I created a friendly 'Earth' character to make inviting friends feel like a playful mission. I unified these elements with a bold, minimal color system. To ensure efficient motion performance, I proposed adopting Lottie files, which was a first for our team. Although the technology was new to me as well, I rapidly upskilled myself to produce and implement these animations directly, successfully transforming mundane data into delightful daily achievements.
