App Design · Ecommerce Experiences

Mobile app design services for your customers’ everyday tasks.

Shape the flows, navigation, and interface of your ecommerce app around what customers need to do. We create a focused prototype and documented design decisions for your development team.

Our app service covers UX and UI design. App development and store publishing require a separate scope.

What should customers be able to do in your app?

Start with the tasks and situations the app needs to support. An existing experience may need clearer navigation or better handling of interruptions. A proposed app needs a defined purpose before its screens take shape.

  • An existing app

    Review the journeys where customers lose their place, miss information, or struggle to recover from an error.

  • A proposed experience

    Define the customer need and the role of the app alongside your mobile website.

  • A redesign

    Identify what should change and what customers already rely on.

  • An implementation team

    Give the people building the app clear flows, interface states, and design decisions.

  • Not sure an app is the answer?

    If your priority is the mobile website, explore Web Design. If the customer need is still unclear, UX Research can help define the questions to investigate.

Define the flow before filling the screens.

We agree on the journeys and platforms the design should cover, then connect structure, interaction, and interface detail. Platform coverage, research, and validation rounds are agreed for each project.

  • Flows and navigation

    Map the steps, decisions, and routes customers need for the selected tasks.

  • Wireframes

    Explore content priorities and screen structure before refining the interface.

  • App UI design

    Design the selected screens, controls, and states around your brand and platform context.

  • Interaction prototype

    Connect the agreed flows so your team can review behavior and test specific questions.

  • Design documentation

    Record behavior, content requirements, dependencies, and decisions for implementation.

Account for the platform and the context of use.

A useful mobile interface needs more than smaller screens. We consider how people navigate, enter information, receive feedback, and return to a task after an interruption. We agree on the platforms and device coverage before design begins.

  • iOS app design

    Adapt the selected experience to iOS conventions and the capabilities agreed with your development team.

  • Android app design

    Define Android behavior and interface decisions when Android is part of the scope.

  • Interaction and recovery

    Make actions, progress, and recovery paths clear across the states the flow needs.

  • Accessible design

    Consider readable content, usable controls, alternative interactions, and accessibility notes for implementation.

Connect customer evidence with design decisions.

When user testing is in scope, we recruit for the selected tasks, record what the prototype can demonstrate, and prioritize findings for the next iteration. We define how to assess the experience and how it connects with the business questions behind the project.

  1. Discover

    Review the customer context, existing evidence, and product constraints. Define the questions that need research.

  2. Define

    Agree on the tasks, platforms, scope, and criteria the design should address.

  3. Develop

    Explore flows and interface options, then use a prototype to review and refine the selected experience.

  4. Deliver

    Organize the design files, document decisions, and walk the implementation team through the agreed flows.

Give your development team a clear design reference.

The handoff brings the selected journeys, interface detail, and open questions together. Code, backend services, integrations, app store submission, and ongoing technical maintenance are scoped separately.

  • Flow reference: agreed journeys, decisions, and navigation routes.
  • Design files: wireframes and interface designs for the selected screens and states.
  • Prototype: a connected representation of the agreed interactions, with its simulation limits stated.
  • Design notes: behavior, content, accessibility considerations, and dependencies.
  • Findings and priorities: documented observations and next actions when research or testing is included.
  • Handoff walkthrough: a review of design decisions and the questions your implementation team needs to resolve.

Questions about mobile app design services.

This service covers UX and UI design, a prototype, and design documentation. Development, integrations, and app store publishing require a separate scope.

We define the work around the selected customer tasks, available evidence, and product constraints. That may involve refining an existing experience or designing a proposed flow.

The decision depends on the customer need, the role of the mobile website, and your ability to build and maintain the experience. We start by clarifying the task the app should support.

Platform coverage is agreed for each project. The design needs to account for the conventions and implementation constraints of the selected platforms.

Testing is agreed around specific questions, participants, and tasks. We document what the prototype simulates and the limits of the findings.

The scope depends on the journeys, platforms, interaction states, research needs, and review rounds. We define those requirements before preparing a proposal.

Design helps your team examine how the experience supports customer tasks. Retention and sales depend on the implemented product, customer behavior, and the wider commercial context; they are not guaranteed by a design project.
