What is included in UI/UX design services?

App369's UI/UX design services encompass the full design lifecycle: user research, persona development, information architecture, wireframing, interactive prototyping, visual design, usability testing, and design system creation. We use Figma for collaborative design and deliver developer-ready assets with detailed specifications, spacing tokens, and component documentation.

How does good UI/UX design impact business results?

App369 applies data-driven design principles, A/B testing, and heatmap analysis to ensure every design decision directly impacts your bottom line.

What design tools does App369 use?

Figma enables real-time collaboration, interactive prototyping, and structured developer handoff with auto-generated CSS and design tokens. We also use Adobe Creative Suite for asset creation, Maze for remote usability testing, and Hotjar for heatmap analysis. All deliverables are organized in shared Figma workspaces with version control.

How long does the design process take?

The design process typically takes 3-8 weeks depending on project scope. Discovery and user research requires 1-2 weeks, wireframing and information architecture takes 1-2 weeks, visual design and prototyping takes 2-3 weeks, and usability testing with iteration adds 1-2 weeks. For larger projects with multiple user flows, the process can extend to 10-12 weeks.

Do you offer design-only services without development?

Yes, App369 offers standalone design services for clients who have their own development teams. We deliver complete Figma files with interactive prototypes, design systems with reusable components, detailed style guides, and developer handoff documentation. Our design deliverables include responsive layouts for mobile, tablet, and desktop, along with accessibility compliance audits aligned with WCAG 2.1 AA standards.
