App
Development

Native and cross-platform mobile applications built with Swift, Kotlin, and Flutter. Enterprise-grade architecture, consumer-grade UX.

Apps that people
actually use.

80% of mobile apps are abandoned after first use. We build the other 20%. Every app we deliver is obsessively designed for real user behaviour, rigorously tested across devices, and architected to handle growth from hundreds to millions of users.

Capabilities

Every solution is bespoke, production-grade, and engineered to deliver measurable results.

iOS Development

Native iPhone and iPad applications built with Swift and SwiftUI. Pixel-perfect interfaces that follow Apple's Human Interface Guidelines while standing out from the crowd. Optimised for the latest iOS features and hardware.

We build native iOS applications that feel at home on iPhone and iPad — fast, fluid, and following Apple's Human Interface Guidelines for seamless user experiences.

Our Approach
  • Define your app's core value proposition and feature set
  • Design native iOS interfaces that users already know how to use
  • Build with native frameworks for maximum performance and reliability
  • Handle App Store submission, review process, and launch
Tech Stack
Swift, SwiftUI, UIKit, Core Data, CloudKit, TestFlight, Xcode
Deliverables
Production iOS app, App Store listing, TestFlight beta, crash reporting, analytics integration
Timeline
8–12 weeks
Starting From
From £10,000

Android Development

Native Android applications built with Kotlin and Jetpack Compose. Material Design 3 interfaces that feel natural across the entire Android ecosystem — phones, tablets, foldables, and wearables.

We build native Android apps that perform beautifully across the entire device ecosystem — from budget phones to flagship tablets, with Material Design 3 polish.

Our Approach
  • Map device targets and Android version support requirements
  • Design Material Design interfaces optimised for Android patterns
  • Build with Kotlin and Jetpack Compose for modern, maintainable code
  • Test across device matrix and handle Play Store submission

Cross-Platform (Flutter)

Single codebase, multiple platforms. Flutter apps that look and feel native on both iOS and Android. 60–70% faster development time compared to building two separate native apps without sacrificing quality.

One codebase, two platforms. Flutter lets us ship to iOS and Android simultaneously, cutting your development time and budget while maintaining native-quality performance.

Our Approach
  • Evaluate if cross-platform suits your app's requirements
  • Design a shared UI that respects both iOS and Android conventions
  • Build with Flutter for near-native performance from a single codebase
  • Ship to both App Store and Play Store simultaneously
Tech Stack
Flutter, Dart, Firebase, platform channels for native features, Riverpod/Bloc
Deliverables
iOS and Android apps from single codebase, store listings, CI/CD pipeline, shared testing suite
Timeline
6–10 weeks
Starting From
From £8,000

MVP & Prototype Development

Get to market fast with a production-quality minimum viable product. We strip down to core features, build rapidly, and iterate based on real user feedback. Perfect for validating ideas before full investment.

Get your idea in front of real users as fast as possible. We build functional MVPs that validate your concept, attract investment, and give you real data to iterate on.

Our Approach
  • Run a discovery sprint to define the smallest viable feature set
  • Build a clickable prototype for user testing before any development
  • Develop the MVP with production-quality code — no throwaway work
  • Launch to early users and set up analytics to measure what matters
Tech Stack
React Native or Flutter, Firebase, Supabase, Vercel, rapid prototyping tools
Deliverables
Working MVP, user analytics, feedback collection system, investor-ready demo, iteration roadmap
Timeline
4–8 weeks
Starting From
From £6,000

App Redesign & Modernisation

Legacy app holding you back? We redesign outdated interfaces, refactor aging codebases, migrate to modern architectures, and optimise performance. New life for existing products.

Your app works but it feels dated, slow, or frustrating. We redesign the experience, modernise the tech stack, and rebuild for the performance users expect today.

Our Approach
  • Audit current app: UX pain points, performance bottlenecks, tech debt
  • Redesign the experience based on user feedback and analytics data
  • Rebuild on a modern stack or refactor incrementally with zero downtime
  • Migrate existing users seamlessly to the new version
Tech Stack
Modern frameworks (Swift/Kotlin/Flutter), architecture refactoring, incremental migration
Deliverables
Redesigned app, migration plan, performance benchmarks, user transition strategy, updated store listing
Timeline
6–12 weeks
Starting From
From £8,000

Backend & API Development

Every great app needs a great backend. Scalable APIs, real-time data sync, push notifications, user authentication, and cloud infrastructure designed to handle growth without breaking.

The invisible foundation your app depends on. We build scalable, secure backends that handle authentication, data, payments, push notifications, and third-party integrations.

Our Approach
  • Architect the database schema and API structure for your app's needs
  • Build authentication, authorisation, and role-based access
  • Implement real-time features, push notifications, and webhooks
  • Deploy with auto-scaling, monitoring, and backup systems
Tech Stack
Node.js, Python, PostgreSQL, Firebase, AWS Lambda, GraphQL, WebSockets, Redis
Deliverables
Production API, documentation, authentication system, admin panel, monitoring, auto-scaling
Timeline
3–6 weeks
Starting From
From £4,000

App Store Optimisation

Getting featured matters. We optimise your app store listing — screenshots, descriptions, keywords, and metadata — to maximise organic downloads and visibility.

Getting into the App Store is step one. Getting found is the real challenge. We optimise your listing to rank for the right keywords and convert browsers into downloads.

Our Approach
  • Research keywords your target users actually search for
  • Optimise title, subtitle, description, and keyword fields
  • Design screenshots and preview videos that drive installs
  • Set up A/B tests on store listing elements and track conversion rates
Tech Stack
App Store Connect, Google Play Console, ASO tools, A/B testing frameworks
Deliverables
Optimised store listings, keyword strategy, screenshot designs, conversion tracking, monthly reports
Timeline
1–2 weeks (initial), ongoing optimisation
Starting From
From £1,500

Post-Launch Support

Bug fixes, OS updates, feature releases, analytics monitoring, and performance optimisation. We maintain your app so it stays fast, stable, and competitive long after launch.

Launch day is just the beginning. We provide ongoing support to fix bugs, ship updates, monitor performance, and grow your user base with new features.

Our Approach
  • Set up crash reporting, performance monitoring, and user analytics
  • Provide priority bug fixes and OS compatibility updates
  • Plan and build new features based on user feedback and data
  • Handle store submissions, review responses, and version management
Tech Stack
Sentry, Firebase Analytics, Mixpanel, TestFlight, Play Console, CI/CD

Common questions

Should I build native or cross-platform? +
If budget and speed matter most: cross-platform (Flutter). If you need maximum performance or deep OS integration: native. We'll recommend the best approach based on your requirements, budget, and timeline during our free discovery call.
How much does an app cost? +
Simple apps start from £8,000. Medium-complexity apps: £15,000–£30,000. Complex enterprise apps: £30,000+. We scope everything during discovery and provide a fixed-price quote with no surprises.
How long does it take to build an app? +
MVP: 6–8 weeks. Full-featured app: 10–16 weeks. Complex apps: 16–24 weeks. We use agile sprints with weekly demos so you see real progress every week.
Do you handle App Store submission? +
Yes. We handle the entire submission process for both Apple App Store and Google Play Store, including compliance, metadata, screenshots, and review responses.

+
A typical MVP takes 6-10 weeks from discovery to launch. We start with a 1-2 week discovery sprint to define core features, then design and build in agile sprints with weekly demos.
Do you build for iOS and Android?
+
Yes. We build native iOS and Android apps as well as cross-platform solutions using React Native and Flutter. We recommend the best approach based on your budget, timeline, and requirements.
Can you scale the app after launch?
+
Absolutely. We architect every app for scale from day one using cloud-native infrastructure. Our monthly retainer packages cover ongoing development, monitoring, and feature additions.
