Created a two-part Android application for Jepreto, meeting the needs of booth managers in the case of easy setup and of guests who do not want to learn anything while using it. Rather than just making an app based on the existing desktop one, the approach here was to concentrate on system visibility and recovery from errors to avoid “silent failures” (e.g., printer malfunction without any messages). Main methods include creating a single “Booth Readiness” screen, designing failures as dedicated screens that can be easily recovered from, and making an adaptive onboarding process for beginners and experienced booth managers.
