Abstract
This study aims to evaluate the usability of two Food Delivery Apps (FDAs) available in the marketwith a sample of older adults. We performed a usability study of basic tasks required to purchasegroceries with 12 participants (Mage ¼ 70.92, SD ¼ 4.56). Results showed that interaction experi-ence with both apps was similar. Most participants could perform the tasks, but not efficiently.Tasks that took the longest mean time were adding the first product to the cart and schedulingthe delivery service. We found 22 interface barriers for FDA1 and 23 for FDA2. The most frequenterrors were caused by a lack of a clear roadmap to guide the purchase process, unclear feedbackwhen adding products, information overload, and difficulty distinguishing interactive buttons fromtext/icons and mandatory actions from optional ones. System Usability Scale results were belowthe suggested cut-off point of 68. We provide recommendations that could help design accessibleFDAs for older adults and make them easier to use for everyone
