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