Mobile App Design

About this Service

Most B2B SaaS platforms start on desktop. Mobile comes later, if at all. When it does, teams squeeze the desktop layout into a phone screen and call it responsive. Users get tiny buttons, broken tables, and workflows that need ten swipes to do what took one click on desktop.

UITOP designs mobile apps for B2B SaaS as standalone products. We rethink navigation for a small screen instead of shrinking what worked on desktop. We simplify data-heavy screens, design for one-handed use, and account for bad connections and outdoor glare.

What you get:

  • UX research focused on mobile usage patterns and context (field, office, commute)

  • Screen designs for iOS and Android

  • Interactive Figma prototypes for testing on real devices

  • Mobile-specific design system with touch-friendly components

  • Responsive layouts that work across phone and tablet

  • Developer handoff with platform-specific specs

Tools

  • Figma for core UI/UX design, interactive prototypes, component systems, and developer specs

  • Claude, Lovable for AI-assisted research, flow mapping, and functional prototyping that feel like the real product

  • Slack, Google Meet, Zoom for communication

  • If your team already works in a specific tool, we jump right into your workspace

Process and Communication

  1. Discovery. We review your product, your target users, and their daily mobile habits.

  2. User flows. We map out step-by-step user paths before drawing any screens. This catches structural problems early, when they're fast, cheap and easy to fix.

  3. Wireframing. We build simple layouts to define screen hierarchy and content placement before adding visual styles. It shows what goes where, so you can react before visual polish.

  4. UI/UX design. We design full, high-fidelity screens using native iOS and Android patterns so the interface feels natural on mobile devices.

  5. Prototyping. We wire screens together into a clickable prototype you can open and test directly on a smartphone.

  6. Handoff and support. We prepare organized Figma specs and UI components for your engineering team, then stay available for support during the build.

Why Mobile UX Matters

  • Users complete tasks without switching back to desktop

  • Fewer support tickets from confused mobile users

  • Faster adoption from field or on-the-go teams

  • A product that works the same no matter which screen someone picks up

Your desktop users and your mobile users are often the same people at different moments. The app should feel like one product either way. Let's design yours.
