Mobile apps that users keep on their home screen.
We design and build iOS and Android apps that feel native on both platforms. From concept to App Store, we handle the entire lifecycle — including the updates that keep users engaged.
Mobile apps that earn their place on the home screen.
We've been building mobile products long enough to know that a beautiful UI is table stakes. What separates the apps people keep from the ones they delete in a week is the invisible work — performance budgets, offline resilience, push notification strategy, and obsessive attention to the 200-millisecond interactions that define perceived quality.
Cross-Platform Efficiency
One codebase, two platforms. We build in React Native and Flutter to ship iOS and Android simultaneously — cutting your timeline in half without compromising native feel.
60fps or Nothing
Smooth animations, instant transitions, and sub-second load times. We optimise every render cycle and memory allocation because users can feel the difference even if they can't articulate it.
App Store Ready
We handle the entire submission process — from ASO (App Store Optimisation) to compliance review, screenshot generation, and metadata strategy. Your app launches without a single rejection.
Native performance meets cross-platform pragmatism.
The "native vs. cross-platform" debate is dead. Modern frameworks like React Native and Flutter deliver native-compiled performance while letting you ship to both platforms from a single codebase. We choose the right approach based on your product requirements, not dogma.
- React Native for products with heavy web-to-mobile code sharing
- Flutter for pixel-perfect custom UI and animation-heavy experiences
- Swift and Kotlin for performance-critical native modules
- Shared backend APIs that serve web, iOS, and Android simultaneously
- Push notifications, deep linking, and in-app purchase integration
Designed for thumbs, built for humans.
Mobile UX is a fundamentally different discipline to web design. Smaller screens demand ruthless prioritisation. Touch targets need to be forgiving. Navigation must be discoverable without a tutorial. We design every interaction for the context people actually use their phones — one-handed on the tube, glancing between meetings, or killing time in a queue.
- Gesture-based navigation patterns that feel intuitive
- Offline-first architecture for unreliable connectivity
- Adaptive layouts across phone sizes and foldable devices
- Micro-animations that provide feedback and delight
- Accessibility compliance for VoiceOver and TalkBack
The backend your app deserves.
A beautiful frontend is worthless without a backend that can keep up. We build the server-side infrastructure that powers your app — real-time sync, user authentication, media processing, payment handling, and the API layer that ties it all together.
- Real-time data sync across devices with conflict resolution
- Secure authentication with biometrics, SSO, and MFA support
- Media pipelines for image/video upload, compression, and CDN delivery
- Background job processing for notifications, emails, and reports
- Crash reporting, performance monitoring, and remote config
From concept to the App Store in six phases.
Discovery
Market analysis, user personas, feature prioritisation.
UX Design
Wireframes, user flows, interactive prototypes.
UI Design
Visual design, component library, platform conventions.
Development
Sprint-based builds, automated testing, CI/CD pipeline.
QA & Launch
Device testing, store submission, phased rollout.
Iterate
Analytics review, user feedback loops, feature updates.
Native, cross-platform, or not an app at all.
Before anything else, it is worth establishing that you need an app. A great many products that were built as apps should have been responsive websites, and discovered it after paying for two codebases and an app store presence nobody downloaded.
You probably do not need an app if the value is content or transactions people access occasionally, there is no offline requirement, and you do not need push notifications, the camera or device sensors. Users install very few apps and abandon most of them quickly. A fast mobile site has no install friction at all.
Cross-platform — React Native or Flutter — is the right default when you do need an app. One codebase, both platforms, roughly 70% of the cost of building twice, and for the overwhelming majority of products the user cannot tell. This is what we recommend most often.
Native earns its cost when performance or platform integration is the product: heavy graphics, real-time media, complex background behaviour, or deep use of platform-specific capabilities. If that is you, building twice is the honest answer and we will say so.
Our app development lifecycle guide walks through the whole sequence.
App pricing, and the part nobody quotes.
The build is the smaller half of the lifetime cost. Plan for the rest before you start.
Focused app — from £20,000
Cross-platform, one core workflow, both stores. Enough to put something real in users' hands and learn from it.
Full product — £35,000+
Accounts, payments, notifications, offline handling, analytics and the backend underneath. Most commercial apps land here.
Complex & native — up to £90,000
Two native codebases, hardware or media integration, or regulated data. Our largest mobile engagements.
The ongoing cost
iOS and Android ship breaking changes annually. An app with no maintenance budget stops working within about two years — budget for it at the outset rather than discovering it later.
Store submission is a phase, not an afterthought.
Most delays in app projects happen after the build is finished. We plan for review, rejection and phased rollout from the start.
Product definition
What the app does that a website could not. If we cannot answer that clearly, we say so before you spend money.
Design
Flows and interface for both platforms, respecting the conventions each one's users already expect.
Build
Sprint-based on your chosen stack, with TestFlight and internal test tracks from early on.
Backend & integration
API, accounts, payments, notifications and analytics. Usually shared with your web platform.
QA
Real devices, not just simulators. Poor connections, interrupted sessions, low battery and permission refusals.
Submission & rollout
Store listings, privacy declarations, review responses and a phased release rather than everyone at once.
Do you actually need an app?
This is the question worth answering honestly before anything else, because the cost of getting it wrong is two codebases and a store listing nobody downloads.
You are probably a good fit if:
- Repeated use. People will open it weekly or more. Apps earn their install through habit; occasional use belongs on the web.
- Device capabilities. Camera, location, sensors, Bluetooth or genuine background behaviour.
- Offline requirement. Users work where signal is unreliable — sites, warehouses, transit, aircraft.
- Notifications matter. Push is genuinely central to the product rather than a marketing afterthought.
- Performance is the product. Real-time media, heavy graphics or interaction the web cannot match.
We are probably the wrong choice if:
- It is content or occasional transactions. A fast mobile site has no install friction and reaches everyone.
- The reason is credibility. “Serious companies have apps” is an expensive way to buy reassurance. An unused app in a store is worse than no app.
- There is no maintenance budget. iOS and Android ship breaking changes annually; an unmaintained app stops working within about two years.
- Nobody knows how users will find it. App stores are not a distribution strategy. Downloads need driving, and that budget is usually forgotten.
We will work through this properly on the first call. If the answer is that you need a better mobile site rather than an app, that is what we will say — and it is work we would rather do well than an app we do not believe in.
