An app design is the art of producing an interactive digital product. The use of technology in this field has paved the way for more complex designs. For example, if you are looking for a designer for an app, you would want to find one who is familiar with both the interface and the technology used in creating the app, since both are integral to making the app successful. It is important to note that there are different types of UI design; you would not want to hire a UI designer who only understands the Adobe Flash interface, since the Apple iOS lacks this technology. You should search for designers who know how to create unique user interfaces for both the Apple and Android platforms.
