App UI/UX Design.
Design That Makes People Want to Use Your App.

Most apps fail because of poor user experience, not poor engineering. We design mobile interfaces that are clear, intuitive and built around how real users actually think and behave on a screen.

App UI/UX Design? UI design is how an app looks. UX design is how it works. Good app design means every screen is immediately understandable, every action has a clear path and users can accomplish what they came to do without friction. It is the difference between an app people recommend and an app people abandon.

Why Design Drives Results

88%
Of users are less likely to return after a bad user experience
200%
Average conversion lift from well-designed user flows versus unoptimised ones
5X
Higher cost to fix a UX problem in development than to solve it in the design stage
Why Design Comes First

A Well-Designed App Costs Less to Build and Performs Better After Launch

Most app budgets are spent on development. Most app failures come from design problems. Getting the design right before a single line of code is written is the most cost-effective decision you can make on a mobile project.

A designer working on a prototype can test and fix a user flow in hours. A developer making the same change mid-build takes days and often breaks something else in the process. The 5x cost rule is real and well-documented across the industry.

We treat design as a core product discipline, not a visual layer added at the end. Every screen we design is tested against real user behaviour patterns before it becomes a development specification.

Platform Guidelines Matter

iOS and Android users have different expectations. Buttons, navigation patterns, gestures and feedback all work differently on each platform. We design for each platform’s conventions so users feel at home immediately, without a learning curve.

Design Reduces Development Rework

A complete, approved design with a clickable prototype removes ambiguity from development. Developers build to a clear specification. There is no guessing about layout, spacing, interaction states or edge cases.

User Testing Before You Build

We test key user flows with real users on prototypes before development starts. Finding that a checkout flow has a friction point in a Figma file costs nothing. Finding it after development costs a significant amount to fix.

What We Do

Every Stage of App Design, Covered

We work across the full design process from initial research through to developer-ready handoff files.

User Research and Personas

We define who your users are, what they need and how they think before any screen is designed. User personas and journey maps give the entire team a shared understanding of who the app is actually built for.

Information Architecture

Before any visual design, we map how the app is structured. Navigation hierarchy, content grouping and user flow logic all get defined at this stage so the design is built on a solid foundation.

Wireframing

Low-fidelity wireframes for every key screen. Layout, content hierarchy and user flows all locked down before visual design begins. Changes at this stage cost minutes, not days.

UI Design and Visual System

High-fidelity screen designs with a full visual system. Typography, colour palette, spacing, component library and icon set all defined consistently so the app looks intentional, not assembled from parts.

Clickable Prototype

A fully interactive prototype of the app built in Figma. Every button navigates to the right screen, every key interaction is demonstrated. You can walk through the entire app before development begins.

Developer Handoff

Complete design specifications for developers. Exact measurements, spacing values, colour codes, component states and interaction notes all documented so developers can build precisely what was designed.

Our Design Process

How We Go From Brief to Approved Design

Our design process is structured to catch problems early, get stakeholder alignment at each stage and deliver developer-ready files that eliminate ambiguity from the build phase.

Most design projects move through five stages over 3 to 6 weeks depending on app complexity. You review and approve at each stage before we move forward. Nothing advances without your sign-off.

01

Discovery and Research

We understand your users, your competitors and your business goals. User personas, competitive audit and design brief all completed before any screens are started.

02

Information Architecture

We map the app structure. Navigation, user flows and content hierarchy all defined and approved before visual design begins. The structure determines how well the app works.

03

Wireframes

Low-fidelity layouts for every key screen. You review every user flow at this stage. Content, layout and navigation are locked before we add visual design on top.

04

Visual Design and Prototype

High-fidelity screens with full visual system and a clickable Figma prototype. You experience the complete app before any development work begins.

05

Developer Handoff

Complete specification files with measurements, assets, component states and interaction notes. Developers get everything they need to build accurately without guessing.

Tools We Use

Industry-Standard Design Tools

We work with the same tools your development team already knows, so handoff is clean and there are no file format issues mid-project.

Figma
Primary design and prototyping tool. Used for all wireframes, UI design and interactive prototypes
FigJam
Used for user journey mapping, information architecture and collaborative workshop sessions
Maze
Remote usability testing on prototypes. We validate key flows with real users before development starts
Zeplin
Developer handoff. Precise measurements, assets and specifications extracted automatically for the dev team

Who This Is For

App UI/UX design is for any business building a mobile product that needs to work properly for real users.

Businesses building a new app and wanting design validated before committing to development costs

Companies with an existing app that has poor retention, low engagement or frequent user complaints about usability

Development teams that need a professional design system and complete Figma files to build from

Startups validating a product concept with a prototype before raising funding or committing to a full build

Businesses redesigning an existing app that has grown beyond its original design and needs a coherent overhaul

Book Free Consultation
A standard mobile app design project typically takes 3 to 6 weeks from kickoff to developer-ready handoff files. Simpler apps with 10 to 20 screens can be done in 3 weeks. More complex apps with multiple user roles, complex flows or bespoke component systems take 5 to 8 weeks. We give a specific estimate after reviewing your app scope.
Yes. When both platforms are in scope we design for each with platform-appropriate interaction patterns. iOS and Android have different navigation conventions, button styles, system fonts and gesture behaviours. We respect those differences rather than applying one design to both and hoping it works.
Yes. Redesign projects are a significant part of what we do. We start with a UX audit of the existing app, identify the friction points causing drop-off or negative reviews and design improvements that address those specific problems. We can work on individual user flows or complete full redesigns depending on what the app needs.
Developers receive a complete Figma file with all screens, a design system with named components and variables, exported assets in correct sizes for iOS and Android, interaction notes for every non-obvious behaviour and a Zeplin or Figma Dev Mode link with exact measurements and CSS values. There is no ambiguity left for developers to interpret.
Yes. Many of our clients come to us for design first and then move into development with the same team. Working with one team across both phases eliminates the handoff gap that causes problems when design and development are done by different agencies. If you have your own development team, we are equally happy to hand off the files and support them through the build.
