Retailer mobile applications are one of the principal retail purchase and information search channels. Customer experience is key to retail app success. However, its dimensions and impact on retailer performance have been the subject of only a limited number of studies. This research builds on existing customer retail app experience literature by considering four dimensions as precursors of satisfaction with the retailers’ app and customer loyalty (cognitive, affective, relational and sensorial). Data were collected from a sample of 545 retailer app users and analysed using PLS-SEM. The results demonstrate that the affective dimension has the most influence and they highlight the importance of the sensory experience, which even surpasses the cognitive experience. The effect of the relational dimension on customer satisfaction, meanwhile, could not be positively confirmed. Analysis of the moderating effect of gender, age and device type used identifies effects that have not, until now, been demonstrated in current literature. •The customer retail app experience contributes towards customer retailer loyalty.•Affective, sensorial and cognitive experiences influence customer satisfaction.•Customer satisfaction mediates the effect of experience on customer loyalty.•Age, gender and device type used moderate customer experience.•The effect of relational experience on customer satisfaction could not be supported.
