Mobile App Development

Apps that work on iOS & Android one build

We build Flutter mobile applications that run natively on both platforms - no compromise on performance, no double the cost. From healthcare to ecommerce, shipped to both stores and maintained long-term

WHY IT MATTERS

A mobile app isn't just a smaller website

Mobile apps enable capabilities a browser can't - offline access, push notifications, device hardware, and a direct icon on your user's home screen. The bar is higher. So is the return

Always accessible

An app on the home screen means your product is one tap away - not buried in a browser tab competing with everything else

Push & engage

Push notifications, in-app messaging, and personalised flows drive retention in ways a website simply cannot match

Offline-capable

Critical data can be cached and available without a connection - essential for field teams, healthcare workers, and enterprise use

Store credibility

Being listed on the App Store and Google Play adds a layer of trust and discoverability that drives downloads and builds brand confidence

WHAT WE BUILD

Apps built around real business use cases

We help you convert an app idea into a practical product: user flows, design, development, backend, integrations, testing, and launch support

Choose Your App Type

Not every app needs the same approach

A clinical coordination tool, a consumer ecommerce app, a B2B field service app, and an internal team tool have completely different requirements. We help you scope the right solution instead of overbuilding

Choosing the right website type for your business goals

Need a customer-facing app?

For businesses selling to end users - ecommerce, bookings, service access, subscriptions, or loyalty

Recommended

Flutter cross-platform + payment gateway + push notifications.

Need an internal team app?

For field teams, clinical staff, warehouse operatives, or internal workflows that need mobile access

Recommended

Flutter with role-based access + offline mode + backend API.

Need a SaaS companion app?

Mobile extension of an existing web platform - synced data, mobile-optimised flows, and native notifications

Recommended

Flutter + existing API integration + real-time sync.

Need maximum platform control?

Specific hardware access, complex animations, or performance-critical features requiring full native capability

Recommended

Native Swift (iOS) or Kotlin (Android) development.

PROCESS

From idea to both stores - structured

Five stages from concept to App Store and Google Play. App submissions have specific requirements - we handle all of it so you don't have to

  1. 1

    Discovery & scope

    User flows, platform requirements, device features needed (camera, GPS, push, offline), API integrations, and App Store compliance considerations

    RequirementsPlatform ChoiceUser Flows
  2. 2

    UI/UX design

    Mobile-first Figma design following iOS and Android platform conventions. Interactive prototype reviewed before a single line of code is written

  3. 3

    Development & integration

    Flutter build with backend API, authentication, push notifications, device features, and third-party integrations in structured sprints

HOW WE ENGAGE

Three ways to work with us on mobile

Direct client, white label for agencies, or an ongoing mobile development retainer

App project

Scoped, designed, built, and submitted to both stores. Full handover including source code, store accounts, and documentation

  • Both iOS and Android from one Flutter build
  • App Store and Google Play submission included
  • Full source code and documentation on handover

Agency partner

We build the app under your agency brand. Your client sees your name – we handle design, development, and store submission

  • NDA signed as standard
  • Delivered under your brand throughout
  • You manage client relationship, we manage delivery

Ongoing mobile support

Monthly capacity for new features, OS compatibility updates, bug fixes, and performance improvements post-launch

  • iOS and Android OS update compatibility
  • New features added on rolling retainer
  • Crash monitoring and performance optimisation
TOOLS WE USE

Flutter first. Native when needed.

Flutter is our preferred approach for most iOS and Android apps because it supports faster cross-platform delivery. For projects with deeper platform-specific needs, we can also build native iOS and Android apps
