This project focuses on designing the mobile application that accompanies a new smart dog collar equipped with GPS and accelerometer sensors. The collar tracks a dog’s real‑time location and movement patterns, enabling insights into daily activity, rest cycles, agitation, and time spent in specific places.s the Interaction Designer, the goal is to define the app’s concept, core functionalities, information architecture, and user experience, and to create a complete visual and interactive design system.The final outcome was a fully developed high‑fidelity prototype that enables dog owners to monitor their pets’ safety, understand their behavior, and build healthier routines through intuitive, data‑driven features.
