Whether you need a first MVP or an enterprise grade platform, our team can support you from early concept through to launch and long term optimisation.


Section: What we do

Custom mobile apps built around your business

We specialise in custom mobile solutions rather than one size fits all products. Typical work includes:

  • Native and cross platform apps
    iOS and Android using the right mix of native and cross platform technologies to match performance, budget and roadmap.
  • Customer and staff facing products
    Consumer apps that build loyalty and engagement, and internal tools that streamline operations, training or data capture.
  • Connected web and portal experiences
    Web based dashboards, portals and admin tools that sit behind the app to provide reporting, content management and workflow.
  • Ongoing support and optimisation
    Monitoring, analytics, updates and enhancements so your app keeps pace with devices, operating systems and user expectations.

We draw on experience from more than 250 mobile solutions for charities, retailers, staffing providers, membership bodies, healthcare and more. DesignRush+1

Section: Our 4D approach

A structured path from idea to live app

We follow a clear and collaborative 4D framework that keeps stakeholders aligned and reduces delivery risk. Pocket App+1

  1. Discover
    We start by understanding your users, objectives and success measures. Through workshops, stakeholder interviews and user research we clarify the problem to solve and define a realistic roadmap.
  2. Design
    Our product and UX team translate insight into user journeys, information architecture and interface designs. Clickable prototypes allow you to test flows early and gain buy in before committing to build.
  3. Development
    Cross functional teams of engineers, testers and designers work in sprints to deliver secure, performant and maintainable code. We integrate with your existing systems where needed and set up the right environments, pipelines and analytics.
  4. Deploy
    We support app store submissions, enterprise distribution or private deployment models, and make sure you have monitoring, logging and dashboards in place. After launch we review performance and plan the next iteration together.

This structure keeps projects transparent and gives you clear checkpoints for decisions, budgets and scope.


Section: Technology and platforms

Choosing the right tools for your product

We are technology agnostic and choose tools that suit your goals rather than forcing one preferred stack. Typical technologies include:

  • Mobile:
    Native iOS and Android, cross platform frameworks and supporting SDKs.
  • Backend and integrations:
    Cloud hosted APIs and services that integrate with CRMs, ERPs, payment gateways, identity providers and other business systems.
  • Web and portals:
    Responsive web portals and dashboards for admins, staff or partners.

We design for security, performance and maintainability, and work comfortably alongside your internal IT or other suppliers.


Section: Sectors and use cases

Where we add particular value

While we are sector agnostic, we have particular experience in:

  • Sustainability and social impact
    Behaviour change apps, supporter engagement tools and educational experiences.
  • Workforce and operations
    Shift management, training, reporting and on site tools for large distributed teams.
  • Retail and consumer brands
    Loyalty and membership apps, product discovery tools and in store experiences.
  • Property and housing
    Tenant engagement platforms, inspections, reporting and support journeys.
  • Faith, membership and communities
    Everyday faith and community apps that bring content, reflections and events into a simple mobile experience.

This breadth means we can bring proven patterns from one sector into another while still tailoring the experience to your specific users.


How we work with you

Flexible engagement models

Every organisation has different internal capacity, governance and procurement rules. We adapt our engagement to fit, for example:

  • End to end delivery of a new mobile product, from discovery through to support.
  • Working alongside your internal team as a specialist mobile partner.
  • Phased redesigns and modernisation of existing apps.
  • Ongoing support, improvements and feature development for live products.

We are used to collaborating with marketing, digital, IT and operations stakeholders and can work with both formal procurement processes and more agile, discovery led engagements.


Section: Why Pocket App

  • Our senior team has decades of mobile experience and has worked on hundreds of apps since smartphones first entered the enterprise. DesignRush
  • We combine UX, engineering and delivery management within one team rather than outsourcing key steps.
