Design · App UI Design

Mobile app interfaces designed for real hands and real moments.

We design iOS and Android app interfaces that feel native, intuitive and on-brand, from first-launch onboarding to the screens people come back to every day.

Overview

What App UI Design at NAVIX covers

Mobile design has its own rules. Screens are small, attention is short and people use apps on the move. We design for those constraints with thumb-friendly layouts, clear feedback, sensible gestures and patterns that follow each platform's conventions.

You get a complete, development-ready app design covering every key screen, state and edge case, backed by an interactive prototype and a mobile component library.

Problems we solve

  • 01

    A weak first impression

    Onboarding that asks too much too soon loses users. We design onboarding that shows the app's value first.

  • 02

    Cluttered screens

    Designing for desktop and shrinking it makes crowded mobile screens. We decide what matters most on each one.

  • 03

    A platform mismatch

    Apps that ignore iOS and Android conventions feel foreign. We follow native patterns where they matter.

  • 04

    Missing states

    Empty, loading and error states often get forgotten until development. We design them up front.

Key deliverables

The exact scope is agreed for every project. These are the deliverables this service typically includes.

  • App user flows and screen inventory
  • Wireframes for core journeys
  • High-fidelity screens for iOS and Android
  • Onboarding, empty, loading and error states
  • Interactive prototype for testing and demos
  • Mobile design system and icon set
  • App Store and Google Play screenshot designs
  • Developer-ready specifications

Benefits

  • Intuitive from the first tap

    Familiar patterns and clear feedback mean people don't have to learn your app from scratch.

  • Platform-aware

    Your app feels at home on both iOS and Android without becoming two separate designs.

  • Ready for development

    Every state and interaction is specified, so developers build exactly what was designed.

  • Your brand at small sizes

    A visual language that stays recognisable even on a small screen.

Common use cases

  • Startup MVPs
  • Booking and on-demand service apps
  • E-commerce and loyalty apps
  • Fitness, health and lifestyle apps
  • Companion apps for web platforms
  • Redesigns of existing apps

    Product mapping

    We define the core user goals, features and success criteria for the app.

    Interface design

    We design high-fidelity screens, components and micro-interactions.

  4. 04

    Prototype & test

    We build a clickable prototype for usability checks and stakeholder sign-off.

    Developer handoff

    We hand over specs, assets and a component library, and support you through the build.
