Master Apps are integrator platforms that centralize and organize commercial ecosystems—such as cities, shopping malls, marketplaces, trade shows, fairs, and commercial districts—into a single unified experience. They directly integrate RedVIP® Vitrina Apps, customized mini Progressive Web Apps (PWAs) for each business or professional. Each Vitrina App serves as the digital extension of a physical store, stand, or service, while the Master App connects, structures, and contextualizes them within a specific location or market.
