Our Services
Native and cross-platform. Built to last.
We build mobile applications that people actually want to use. From consumer apps to complex enterprise tools, we combine thoughtful UX design with robust engineering to deliver products that perform on iOS and Android.
Whether you need a native app for maximum performance, or a cross-platform solution to reach both audiences efficiently, we'll recommend the right approach for your product and budget — and then build it properly.
Capabilities
Native iOS apps built in Swift, delivering the performance and polish that Apple users expect.
Native Android apps built in Kotlin, optimised for the full range of Android devices and screen sizes.
A single codebase for iOS and Android using Flutter — ideal when speed to market matters and native performance is still required.
Cross-platform apps using React Native for teams with existing web expertise who want to share logic across platforms.
We handle the full submission process for both the App Store and Google Play, including compliance, metadata, and review management.
Post-launch support, OS update compatibility, performance monitoring, and iterative feature development.
Where you might be starting from
Taking over an app another team built is often the fastest route to a better product.
We get it building and releasing reliably first, then improve it in small, regular releases rather than starting again from scratch.
Slinger's React Native app wouldn't compile from a fresh clone when we took it on. It now ships to the App Store on a roughly monthly rhythm.
Renting a white-label app puts your roadmap, and your members' experience, on someone else's platform.
We design and build a bespoke app and platform you own outright, and plan the switch from the app your members use today.
FIT for LIVET moved from a white-label app to a bespoke Flutter platform it owns outright, with medication tracking, weight-loss projections and a recipe community.
Process
01
We start by understanding your users — their goals, behaviours, and pain points — to define an app experience that genuinely works for them.
02
Before any code is written, we prototype the key flows so you can validate the experience early and cheaply.
03
Pixel-perfect, platform-native designs that feel at home on iOS and Android, aligned with your brand.
04
Agile development with continuous testing across real devices to catch issues before they reach your users.
05
We manage the App Store and Google Play submission process end-to-end, including compliance and review management.
06
Ongoing maintenance, OS compatibility updates, and iterative improvements as your app grows.

FAQs
It depends on what the app needs to do. Native Swift and Kotlin give the deepest access to each platform; Flutter and React Native give you one codebase for iOS and Android, which usually means a faster launch and lower running cost. We recommend one after discovery, based on your features, team and roadmap.
Yes. We manage submission to both stores end to end, including compliance, store metadata and responding to review feedback, so the app reaches users without you having to learn either process.
Yes. We regularly pick up apps that have stalled or outgrown their first build. For Slinger we rebuilt a stalled hospitality app while shipping monthly throughout, and we moved FIT for LIVET off a rented white-label app onto a bespoke Flutter platform.
Yes. Most apps we build sit alongside a backend or business system — a CRM, payments, a CMS or an operations tool. For Bruce's Doggy Day Care we built the customer app, the driver app and the custom CRM behind them.
Timelines depend on scope, so we don't quote one before discovery. Work is priced on a fixed fee rather than by the hour, quoted after a scoping call, and you see working builds on real devices early in the project.
Yes. Apps need ongoing care as iOS and Android change. We offer post-launch maintenance, OS compatibility updates, performance monitoring and new feature development under a fixed monthly Continuity arrangement.
