The design process began by mapping user journeys to uncover friction points in the existing web experience. Early wireframes focused on simplifying navigation, consolidating content, and ensuring clear visual hierarchies. Given the app’s role as a communication channel for offers and loyalty updates, each interface was designed for clarity and immediacy, where content leads and visuals follow. The UI leverages a refined dark mode aesthetic, balancing sophistication with accessibility while improving battery performance and reducing visual fatigue. Every decision, from typography rhythm to motion behavior, was guided by Marriott’s brand ethos of comfort, trust, and consistency, resulting in a mobile experience that feels both premium and familiar, where exploration becomes engagement and engagement drives loyalty.
