MOBILE APP DEVELOPMENT

Mobile App Development

I build iOS and Android applications for bookings, customer accounts and the tasks your team needs to complete on the move.

Start with a prototype of the main user flow, then build the app and its backend connections together. A focused first release includes loading, empty and error states, device checks and a plan for store submission.

FOR YOUR CUSTOMERS

Bookings, accounts & customer access

I build the screens and backend connections for bookings, customer accounts and status updates. The first release covers the core task from entry to confirmation.

FOR YOUR TEAM

Internal workflows & field tasks

I build focused interfaces for requests, task updates and team information. Existing APIs and account systems can be connected as part of the agreed scope.

FROM PRODUCT IDEA TO RELEASE

A focused app. A foundation for what comes next.

01

Validate the core task

Map the main user journey and review the screens before expanding the feature list.

02

Build a usable release

Implement the agreed app features, connected API and important loading and error states.

03

Test & prepare release

Review the core flow on agreed devices and prepare builds and store-submission materials.

A connected foundation

Accounts, notifications, data sync or offline behaviour are planned when the product needs them.

A handover you can use

Source code, build instructions and the agreed release notes explain how the app can be maintained.

THE FIRST RELEASE

A first release you can test before expanding.

You get a user flow and prototype to review, followed by the core screens, account behaviour and backend connections. Testing covers the agreed task on the target devices, including loading and error states.

  • User flow and a reviewable prototype
  • Core screens and agreed account behavior
  • Required backend and API connections
  • Device testing and a release plan

SCOPE & OPTIONS

Plan the app around the features people will use.

I separate what the first release needs from what can follow later. The result is a defined set of screens, data and connections to build and test.

Customer bookings & accounts

For services people return to: choosing a time, checking a booking or managing their details.

  • Service selection and booking flow
  • Account access and appointment details
  • The required backend connections

Internal team applications

For requests, field tasks and updates that need a mobile interface.

  • Task lists and status changes
  • Role-based screens and record access
  • Connections to the existing workflow

Connected product features

For an app that needs to work with an existing website, API or account system.

  • Data and account integration
  • Loading, empty and error states
  • Device capabilities reviewed before build

A PLATFORM DECISION, NOT A DEFAULT

Platform planning and Flutter development.

Swipe to explore

iOS & Android requirements

I review device features, existing systems, supported devices and release requirements before the build. You can see which requirements affect the implementation and scope.

Shared app with Flutter

Where the requirements fit, I build a Flutter application with a shared codebase for iOS and Android. The scope covers the app, API connections and the testing needed for release.

WHAT’S INCLUDED

What’s included in mobile app development.

Your first release is built around a complete user task, rather than a long list of disconnected screens. The proposal specifies platforms, user roles, API work, device coverage and release responsibilities.

Requirements & release scope

Users, the core task, required screens, target platforms and the functionality for the first release.

UX, screen design & prototype

Navigation, screen layouts and a reviewable prototype of the main user flow.

Application development

The app screens, interactions and platform requirements, including Flutter where it fits the project.

Accounts & application states

The scoped sign-in behaviour, permissions, loading, empty, success and error states.

Backend & API integration

Connections to the required account system, records, website or other backend services.

Device & workflow testing

The devices, core task, invalid inputs, network interruptions and important recovery paths.

Release preparation

Build configuration and guidance on the account, store listing and assets needed for the release.

Project handover

Agreed project materials, configuration instructions and documentation for managing the application and its dependencies.

BEFORE THE FIRST MESSAGE

Questions about your first app release.

Is an app the right choice for my project?

An app is useful for repeated tasks, customer accounts, notifications or device capabilities. We compare that need with a responsive website before committing to an app build. The first release is scoped around the task people will return to.

Will the app work on both iOS and Android?

The target platforms are confirmed before design and estimation. Flutter can suit a shared iOS and Android codebase; device-specific requirements are reviewed separately so the technical approach fits the product.

Can you use our existing backend and accounts?

I review the API documentation, authentication, data and required operations. Where the system supports the connection, the app can use the existing backend. Missing endpoints or backend changes are identified in the proposal.

What affects the cost of the first release?

The screens, user roles, platforms, API connections and device features drive the scope. A prototype helps confirm the main flow. Optional features stay visible in a later roadmap, and changes are estimated before they are added.

What is needed for an App Store or Google Play release?

Your business needs the relevant developer accounts, product details, privacy information and store assets. I cover the agreed build and release preparation. Store review is an external step, so submission responsibilities are confirmed in the launch plan.

What is handed over, and can the app keep evolving?

You receive the project materials and setup guidance specified in the proposal, including the app and backend dependencies. OS updates, fixes and new features can be planned as a separate ongoing backlog after the first release.

06 / YOUR NEXT BIG MOVE

What should your app make easier?

Describe who will use the app and the one task it must handle well. A sketch, existing workflow or short explanation is enough for an initial conversation.
