The mobile app design cost may include market research, UX/UI design, branding, and additional visuals. The UX and UI design, in turn, involves brainstorming ideas for user journeys, wireframing, prototyping, and iterating until you are happy with the results. At the branding stage, designers will suggest a color palette, work out typography, and design a logo if you don’t have it. At the final stages of UX development, designers will work on custom illustrations and animations if you choose to use them in your app. You can discuss the specifics of the UX design, its timeframe and cost once you choose a team to work on your project.
