The biggest difference between mobile app design and a desktop application or even a website, is context, and this is what sets us apart from competitors. Each app is used for its own purpose, on a specific time and place. If you’re creating a restaurant guide, you’ll want to create something that show the most relevant results to the user in the least time, since the user will probably be on the street or on the move, and is looking for a quick recommendation. This opens a lot of possibilities for innovation in mobile development, and as a designer you should always be informed of and testing the latest apps to be up to date on what is being created.
