When a user finds an application in the app store, the first thing they encounter is the design of the app. Based on the screens and their description, a user determines whether the app is worth downloading or not. Thus, app design plays a crucial role in the user’s decision-making process even before they download an app to their device.

The demand for mobile applications has skyrocketed over the past few years. UI design can make or break the success of almost any digital project. Contemporary designers understand this very well and make every effort to deliver the best outcome possible.

·         Showcases common UI patterns

·         Insightful and simple to use
