SunSense is a smartwatch app designed to help health conscious users, athletes, and outdoor enthusiasts monitor UV exposure and practice safe sun habits. As the sole designer, I developed the full concept, interface, and voice-enabled interactions using Adobe XD, focusing on minimalist design to accommodate the small screen. Key features include a voice-activated UV query, a playful sunscreen timer, and a daily UV trend graph, all aimed at providing quick, actionable, and engaging information. This project taught me how to combine voice interaction with clean visuals, balance usability with screen constraints, and design a health-focused experience that encourages proactive user behavior.
