Coffee Sayer is a unique mobile app that blends the ritual of coffee drinking with personal fortune-telling. Designed for users seeking a daily spark of joy, the app lets users sip their coffee and get personalized fortune insights through engaging and gamified UI screens. We handled the complete UI/UX design, starting from research and user flow mapping to high-fidelity screens and branding. The app includes features like onboarding, mood-based coffee matching, fortune reveals, and daily streak rewards. With a clean and modern interface inspired by minimal aesthetics and soft pastel tones, we ensured the app feels soothing yet captivating. The design system was built with scalability and emotional engagement in mind, allowing room for future gamification layers and social interaction.
