Food delivery apps (FDAs) have transformed the way consumers order and consume food, especially during the mobility limitations of the COVID-19 pandemic. The hospitality industry, especially restaurants are heavily reliant on mobile technology during the pandemic to strengthen essential online to offline food delivery, helping large number of consumers. This study investigates the role of app aesthetics in evoking emotions which predict continued usage intentions for FDAs using the theoretical lens of the pleasure arousal dominance (PAD) framework. Data was collected from 341 consumers during the pandemic. Findings indicate that app aesthetics generate pleasure, arousal, and dominance emotions among consumers during pandemic where pleasure is the most significant predictor of continued usage intentions followed by dominance. Findings also confirm the mediating effect of arousal on pleasure and pleasure on continued usage intentions. The study has implications for academicians, food delivery companies, app designers and other app-based businesses as it proves the significance of an aesthetic app design in evoking positive PAD emotions in consumers during a crisis and strengthens the explanation of continued usage intentions.

送餐应用程序（FDA）已改变了消费者订购和消费食品的方式，尤其是在COVID-19大流行的出行限制期间。在大流行期间，酒店业，尤其是餐馆严重依赖于移动技术，以加强从在线到离线的基本食品交付，从而帮助了众多消费者。这项研究调查了应用美学在唤起情绪中的作用，这些情绪使用愉悦性优势（PAD）框架的理论视角来预测FDA的持续使用意图。大流行期间从341个消费者那里收集了数据。研究结果表明，应用美学在大流行期间会在消费者中产生愉悦，唤醒和主导情绪，其中愉悦感是持续使用意愿继之以主导地位的最重要预测指标。研究结果还证实了唤醒对愉悦感和持续使用意图愉悦感的中介作用。这项研究对院士，食品配送公司，应用程序设计师和其他基于应用程序的业务具有影响，因为它证明了美学应用程序设计在危机期间唤起消费者对PAD积极情绪的重要性，并加强了对持续使用意图的解释。
