Native apps
Apps built properly, on both platforms
Not a website in a shell, and not one cross-platform codebase passed off as two apps. We build native apps for iPhone, iPad and Android with each platform's own tools, so they feel the way your customers expect: light and dark mode, text that scales, VoiceOver and TalkBack, and the navigation each platform already taught them.
- Light and dark, as the system chooses
- Text that scales with the reader
- Each platform's own navigation
- iPhone and iPad from one app, not a stretched phone screen
- Android phones, tablets and foldables, not one fixed layout
- Accessible from day one, built to each platform's design guidelines
iPhone and iPad
Swift and SwiftUI
Apple's own language and frameworks, built in Xcode. Size classes and split view designed in from the start, so the iPad app is a proper iPad app.
Apple Developer Program member
Android
Kotlin and Jetpack Compose
Google's own language and UI toolkit, following Material 3. Layouts that adapt to phones, tablets and foldables rather than one fixed screen.

What our clients say about working with us.
Graham handles everything technical for our shop - email issues, OpenCart updates, BaseLinker integration, logistics automation, reward points, even our Christmas marketing campaigns. He's always quick to respond and nothing is ever too much trouble.
From custom-coded pages and donation systems to cookie policies and newsletter popups - Graham built exactly what we needed. He continues to support us with content updates at affordable charity rates. A genuine pleasure to work with.
I had a backlog of invoices piling up. Invoicer helped me clear through them quickly, get paid faster, and even keep track of sending insurance certificates to clients. Simple, does what it says, perfect for tradespeople.
