Application design and development are two stages of the mobile app development process. These are the stages of the app development process where first the screens are designed and then the mobile app comes to life by bringing in the frontend code and backend code together during the development stage. The design stage usually comes after UX research and analysis. This allows for the UI designs to be focused on the target audience and offers a great user experience to those users. Once the designs are done, they are translated into code which builds the application and connects it to the database. The application design and development stages often merge at some point and might be revisited as quality assurance continues throughout the development stage.
