IFML stands for “Interaction Flow Modeling Language” and it is a way to describe the way in which people interact with websites and applications on their phones or computers. It describes which screens people should see, what buttons they should press, and what choices they should make on each screen. Think of it like a map showing you exactly where you need to go and what to do in order to get where you need to be. It helps people create websites and apps that have great user experiences.
