Mobile App Development Agency

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.

iOS & Android Development

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

Mobile UX Design

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

Backend & Infrastructure

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

Discovery

Market analysis, user personas, feature prioritisation.

02
UX Design

Wireframes, user flows, interactive prototypes.

03
UI Design

Visual design, component library, platform conventions.

04
Development

Sprint-based builds, automated testing, CI/CD pipeline.

05
QA & Launch

Device testing, store submission, phased rollout.

06
Iterate

Analytics review, user feedback loops, feature updates.

Questions about mobile app development.

Unless you have a specific reason to launch on one platform first (e.g., your target audience skews 80%+ iOS), we recommend building for both simultaneously using React Native or Flutter. The cost difference between one platform and two is typically only 15–20% with cross-platform frameworks, and you avoid the technical debt of maintaining two separate codebases later.
A focused MVP typically starts from £20,000 and scales based on complexity. A full-featured app with authentication, payments, real-time features, and backend infrastructure usually falls in the £35,000–£90,000 range. We provide a detailed breakdown during our discovery phase.
Our typical timeline is 10–16 weeks for an MVP, including design, development, testing, and store submission. More complex applications with custom backends, real-time features, or hardware integrations can take 16–24 weeks. We provide a detailed sprint plan after discovery.
Yes — end to end. We handle all aspects of store submission including screenshots, app descriptions, metadata, privacy policy compliance, content rating questionnaires, and review responses. We also implement ASO best practices to maximise your organic discoverability from day one.
Absolutely. Whether you need to connect to an existing API, CRM, payment system, ERP, or legacy database, we build the integration layer that connects your mobile app to your existing infrastructure. We have extensive experience with REST, GraphQL, SOAP, and webhook-based integrations.
Mobile apps require regular updates for OS compatibility, security patches, and feature improvements. We offer ongoing maintenance plans that cover everything from critical bug fixes and OS update compatibility to new feature development and performance optimisation.
