Mobile devices have changed the consumer shopping journey by enabling research and purchasing at every stage. Consumers now use smartphones to initially research products (67% research in-store then buy online), get information while in transit to stores using location-based ads, check product details and wishlists in-store (84% use phones this way), get personalized recommendations, complete self-checkout using mobile payments, and share purchase experiences online (83% rely on social media reviews). Retailers can enhance engagement through mobile apps that integrate these capabilities and remind customers to review purchases, driving continued interaction.
