Custom Software Development.

Bespoke mobile apps, desktop software and WordPress plugins — designed around how your business actually works, engineered properly and looked after long after launch.

01Custom Mobile Apps

Mobile App Development

iPhone, iPad & Android From One Codebase

Whether it's a customer-facing app, a field tool for your team or a brand-new product, we design and develop custom mobile apps for iPhone, iPad and Android. One carefully engineered codebase ships to both the App Store and Google Play — without an app that feels like a compromise on either.

We start with the job the app has to do: who's using it, where, and how often. That shapes everything from the onboarding flow to whether data has to work offline, sync in the background or never leave the device.

Cross-platform app development keeps costs sensible and releases in step. Where an app needs something truly native — the camera, payments, biometrics, widgets or background tasks — we write native modules in Swift and Kotlin.

  • iOS app development
  • Android app development
  • Cross-platform
  • React Native & Expo
  • In-app purchases
  • Push notifications
  • Offline sync

Under the hood

Stack
React Native, Expo and TypeScript, with Swift and Kotlin native modules
Data
SQLite on the device, synced in the background to PostgreSQL through a typed API
Sign-in
Email, Apple and Google sign-in, passkeys and biometric unlock
Payments
In-app purchases and subscriptions through App Store and Google Play billing
Testing
Unit and end-to-end tests, then real iPhones, iPads and Android devices
Delivery
Store submissions handled for you; over-the-air updates for quick fixes

02Custom Desktop Software

Desktop Application Development

Windows, macOS & Linux — Small, Fast, Offline

Some work belongs on a desktop: big screens, large files, long sessions and tools that have to keep running when the internet doesn't. We build custom desktop software for Windows, macOS and Linux, from internal tools to commercial applications.

Our desktop applications pair a Rust core with Tauri, so installers are measured in megabytes, memory use stays low and the app opens in a moment. The interface is built with modern web technology, which keeps it consistent across all three operating systems.

If you're replacing a spreadsheet, an ageing in-house tool or a sluggish Electron app, we'll migrate your data, keep the workflows your team relies on and fix the ones they don't.

  • Windows software
  • macOS apps
  • Linux
  • Tauri & Rust
  • Offline-first
  • Legacy replacement
  • Auto-updates

Under the hood

Stack
Tauri and Rust, with a TypeScript and React interface
Data
Local SQLite or files in folders you choose, with optional encrypted sync
System
File access, printing, notifications, the system tray and local hardware via Rust
Security
Least-privilege permissions; code-signed and notarised builds
Distribution
Microsoft Store, Mac App Store, Flathub or a signed direct download
Updates
Signed automatic updates, installed in the background

03Custom WordPress Plugins

WordPress Plugin Development

Exactly The Feature Your Site Is Missing

When an off-the-shelf plugin almost fits — or you're stacking five of them to fake one feature — a custom WordPress plugin is usually the cleaner answer. We build plugins that do one job well and fit neatly into your site and your workflow.

That might be a booking or quoting system, a members' area, a custom WooCommerce extension, an integration with your CRM or accounting software, or a set of Gutenberg blocks your editors can use without breaking the design.

Every plugin follows the WordPress coding standards, uses the platform's hooks, roles and capabilities properly, and is written to survive core, theme and PHP updates.

  • Custom plugins
  • WooCommerce extensions
  • Gutenberg blocks
  • REST API integrations
  • Custom post types
  • Multisite

Under the hood

Stack
Modern PHP and the WordPress APIs, with React for block editor features
Standards
WordPress Coding Standards; escaping, sanitising and nonces throughout
Data
Custom post types and taxonomies first, custom tables only where they earn it
Integrations
REST API endpoints and webhooks for CRMs, payments and accounting
Performance
Scripts and styles load only where they're used; queries are cached
Handover
Documented, version-controlled code, with updates delivered like any other plugin

04Discovery & Scoping

It Starts With The Problem

Before A Single Line Of Code

Every custom software project begins with a short discovery phase. We talk to the people who'll use it, map the process it has to support and agree what success looks like — then turn that into a clear scope, a prioritised feature list and an honest estimate.

Where it helps, we prototype the riskiest parts first: a tricky integration, an offline sync model or a key screen tested with real users. It's far cheaper to move a sticky note than to rewrite a shipped feature.

  • Workshops
  • User stories
  • Clickable prototypes
  • Technical spikes
  • Prioritised roadmap

Under the hood

You get
A written scope, user flows and a feature list in priority order
Estimate
Broken down by feature, so you can decide what belongs in version one
Prototype
Clickable designs of the key screens before development begins
Risk
Unknowns tested early with small, time-boxed technical spikes

05Architecture & Stack

Built On Solid Foundations

Typed, Tested & Easy To Change

Behind every app is the part nobody sees: the API, the database, sign-in, background jobs and the integrations that tie it into the rest of your business. We design that architecture up front, so the software stays fast and easy to change as it grows.

We favour proven technology over fashionable complexity — TypeScript end to end, PostgreSQL for data, well-documented APIs, and infrastructure a future developer can understand on their first day.

  • TypeScript
  • Node.js
  • PostgreSQL
  • Supabase
  • REST & GraphQL
  • Webhooks
  • Background jobs

Under the hood

API
Typed REST or GraphQL endpoints, versioned and documented
Database
PostgreSQL with migrations, row-level security and automated backups
Accounts
Role-based access, single sign-on where you need it, revocable sessions
Integrations
Payments, email, CRM, accounting and maps through APIs and webhooks
Hosting
Managed cloud infrastructure, in a region chosen to suit your data

06Testing & Security

Tested Before It's Trusted

Quality And Security In Every Release

Automated tests run on every change, from small units of business logic to full end-to-end journeys on real devices. Accessibility and performance are checked alongside them, not bolted on at the end.

Security is designed in from the start: least-privilege access, encryption in transit and at rest, dependency scanning and a code review on every change. With a cybersecurity background at the heart of the studio, it's never an afterthought.

  • Automated testing
  • End-to-end tests
  • Code review
  • Accessibility
  • Dependency scanning
  • Encryption
  • UK GDPR

Under the hood

Tests
Unit, integration and end-to-end, run in CI on every change
Devices
Real iPhone, Android, Windows, macOS and Linux machines
Accessibility
WCAG 2.2 AA as the baseline, checked with tools and by hand
Security
OWASP Top 10 checks, secrets kept out of code, signed builds
Privacy
Data minimisation and privacy-by-design, in line with UK GDPR

07Release & Distribution

Shipped, Not Just Finished

From Build Server To App Store

Launching software is a project in itself. We handle App Store and Google Play submissions, code signing and notarisation, store listings, staged rollouts and the release pipeline that makes every future update routine.

Every change flows through the same automated pipeline — test, build, sign, ship — so releases are predictable, reversible and boring in the best possible way.

  • CI/CD
  • App Store submission
  • Google Play
  • Code signing
  • Staged rollouts
  • Release notes

Under the hood

Pipeline
Automated test, build, sign and release for every tagged version
Mobile
App Store Connect and Google Play Console, with TestFlight and internal testing tracks
Desktop
Microsoft Store, Mac App Store, Flathub and signed installers
WordPress
Versioned releases with in-dashboard updates, or a WordPress.org listing
Rollback
Previous versions kept ready, so a release can be reversed quickly

08Maintenance & Support

Looked After For The Long Run

Updates, Monitoring & New Features

Software is never really finished. Operating systems change, stores update their rules and your business keeps moving. Ongoing maintenance and support keeps your app working, secure and getting better.

That covers operating system and dependency updates, uptime and crash monitoring, security patches and a steady roadmap of improvements — with a direct line to the people who built it.

  • Software maintenance
  • Crash reporting
  • Uptime monitoring
  • Security patches
  • OS updates
  • Feature roadmap

Under the hood

Monitoring
Crash reports, error tracking and uptime alerts
Updates
New iOS, Android, Windows, macOS and WordPress versions tested before release
Security
Dependencies patched and audited on a regular schedule
Roadmap
Regular check-ins to plan and prioritise what comes next

09Questions

Good To Know

How much does custom software development cost?

It depends on the scope: how many platforms, how many features and integrations, and how much needs to work offline. After discovery you get an estimate broken down by feature, so you can choose what belongs in the first version and what can wait. A focused first release is usually the most cost-effective way to start.

How long does it take to build an app?

A focused first version of a mobile or desktop app usually takes a few months from discovery to launch, and a custom WordPress plugin often a few weeks. We agree milestones up front and you'll see working software early and often, rather than waiting for a big reveal.

Should I build a native app or a cross-platform app?

For most apps, cross-platform development with React Native gives you one codebase for iPhone and Android with a native feel and lower costs. We add native Swift and Kotlin code where a feature needs it, and we'll tell you honestly if your app is one of the rare cases that should be fully native.

Can you build a plugin for WooCommerce?

Yes. We build custom WooCommerce extensions — checkout and pricing rules, product types, subscriptions, integrations with stock, shipping and accounting systems — using WooCommerce's own hooks and APIs so they stay compatible as it updates.

Can you take over or rebuild an existing app?

Yes. We start with a review of the code, infrastructure and analytics, fix anything urgent, then recommend whether to improve what's there or rebuild in stages — whichever gives you the best result for the budget.

Do you provide support after launch?

Yes. Ongoing maintenance covers operating system and dependency updates, monitoring, security patches and new features, so your software keeps working as the platforms around it change.
