Designing from features, not tasks
A list of features doesn't tell you what order users need them in or which ones they'll never find. Flows built around tasks do.

Mobile app UI/UX design that is tested with users before it is built
We work out what your users are trying to do, design the shortest path to it, and put a clickable prototype in front of real people before a line of app code is written.
What is Mobile UI/UX Design?
Mobile app UI/UX design is the work of deciding how an app behaves (UX) and how it looks (UI) on a phone or tablet. It covers user research, user flows, information architecture, wireframes, visual design and interactive prototypes, shaped by platform conventions such as Google's Material Design and Apple's Human Interface Guidelines. Good mobile design also accounts for one-handed use, small screens, interruptions and accessibility from the start.
Many apps are designed screen by screen, from a feature list, without anyone watching a real user attempt a real task. The result is onboarding that asks for too much, key actions hidden behind menus, text too small to read, and an iPhone app that behaves like an Android one. Fixing these after development means rebuilding screens; fixing them in a prototype means moving rectangles.
Why apps feel hard to use
Ignoring platform conventions
Android and iOS users expect different navigation, back behavior, controls and system patterns. Copying one platform onto the other feels wrong to half your users.
Accessibility left until later
Low contrast, tiny touch targets and layouts that break with larger text exclude users and are costly to correct after build.
Designs developers can't build
Mockups without states, spacing rules or edge cases force developers to guess, and the shipped app drifts from the design.
Our Mobile UI/UX Design service
User research
Stakeholder interviews, user interviews and a review of competitor apps and support tickets to understand goals, context and pain points.
User flows and information architecture
Maps of each key task from entry to completion, plus the navigation structure that ties them together.
Wireframes
Low-fidelity layouts that settle content, hierarchy and interaction before visual styling, so decisions are cheap to change.
Interactive prototypes and usability testing
Clickable Figma prototypes tested with representative users, with findings fed back into the design before development.
Visual UI design and design system
Typography, color, iconography and components defined once in a design system, with platform variants for Material Design and Apple's Human Interface Guidelines.
Developer handover
Annotated screens with all states (empty, loading, error, offline), spacing tokens, assets and interaction notes for Flutter or native developers.
Included capabilities
- User interviews and task analysis
- Journey maps and user flows
- Low-fidelity wireframes
- Clickable Figma prototypes
- Usability testing sessions
- Material Design and iOS variants
- Design system and component library
- Dark mode and dynamic text sizes
- WCAG-informed accessibility checks
- Empty, loading, error and offline states
What Mobile UI/UX Design changes for your business
Fewer expensive changes in code
Problems found in a prototype are fixed before developers build the wrong thing.
Familiar on each platform
Following Material Design and Apple's guidelines makes the app easier to learn for Android and iPhone users.
More people can use it
Accessible contrast, touch targets and text scaling widen your audience and reduce support requests.
Clear brief for developers
Complete states and a design system mean less guessing and a closer match between design and app.
Where it makes the biggest difference
New app before development
Founders who want the product shaped and tested before committing a development budget.
Redesigning an app users struggle with
Existing apps with poor reviews, low completion rates or heavy support load, redesigned around the tasks that matter.
Internal and field apps
Apps used by staff in warehouses, vehicles or on site, designed for gloves, sunlight, poor connectivity and speed.
Bringing a web product to mobile
Turning a desktop web app or portal into a mobile experience rather than shrinking the same screens.
From research to developer-ready design
Users see a clickable prototype before development begins, when changes still cost very little.
Understand
Business goals, target users, constraints and success measures agreed with stakeholders.
Research
Interviews, competitor review and analysis of existing app data or support requests.
Map
User flows and navigation structure for the core tasks, reviewed with you before any screens.
Wireframe
Low-fidelity layouts for every key screen, iterated quickly on feedback.
Prototype & test
A clickable prototype tested with real users; problems are fixed and retested.
Visual design
Final UI, design system and platform-specific variants for Android and iOS.
Handover & support
Developer-ready files plus design review during development so the build matches the design.
What it connects to
Mobile UI/UX Design
- Figma design files and prototypes
- Shared component libraries
- Design tokens for Flutter themes
- Analytics event planning
- Usability testing sessions
Built with
Security, quality and scale
Privacy by design
Permission requests, consent and data-collection screens designed so users understand what they agree to.
Secure-by-default flows
Login, password reset, biometric prompts and session timeouts designed to be safe without being frustrating.
Research data handling
Interview notes and recordings kept only as long as needed and shared only with the project team.
Scalable design system
Components and tokens structured so new features can be designed consistently as the app grows.
What working with us looks like
Designers who work with developers
Design and development happen in the same project, so designs are checked with Flutter and native developers for buildability early.
Testing, not just mockups
Prototypes go in front of real users before we call a design finished.
Both platforms understood
We design platform-specific details for Android and iOS instead of one compromise for both.
Design through to launch
We stay involved during development to review the build against the design.
What it costs
Fixed-price packages with the scope written down, paid stage by stage. Your project goes live once it's fully paid.

Mobile UI/UX Design: questions we hear most
What is the difference between UI and UX design for mobile apps?
UX design decides how the app works: the tasks, flows, structure and interactions. UI design decides how it looks: layout, typography, color, icons and components. Both are needed, and UX work should come first.
Do Android and iOS apps need different designs?
They should share a brand and core layouts but differ in platform details. Navigation patterns, back behavior, system controls, typography and some gestures follow Material Design on Android and Apple's Human Interface Guidelines on iOS.
Which design tool do you use?
We design and prototype in Figma. You get access to the files, so your team can review, comment and keep them after the project.
Can you redesign an app that is already live?
Yes. We start by reviewing analytics, store reviews and support requests, then test the current app with users to find where they struggle before proposing changes.
How do you make a mobile app accessible?
We design for sufficient color contrast, adequately sized touch targets, support for larger system text, screen reader labels and not relying on color alone. WCAG guidelines and each platform's accessibility guidance inform these checks.
Can we hire you for design only and use our own developers?
Yes. The handover includes all screen states, a component library and interaction notes so any development team can build from it, and we can join design reviews during their build.
