Build pixel-perfect iOS, Android, web, and desktop apps from a single codebase with Impeller-powered native performance. Our Flutter experts deliver 40% faster development with deterministic 120fps animations, AI-ready architecture, and WebAssembly web apps. One team, one codebase, every platform—no compromises.
Choosing the right mobile app development service is key to a successful project. Flutter is the World's most popular cross-platform development framework, developed and maintained by Google. With the revolutionary Impeller rendering engine now standard, Flutter delivers truly native performance with deterministic frame rates—eliminating the "jank" that plagued earlier cross-platform solutions.
Foresight Mobile have successfully delivered over 50 Flutter apps over the last 7 years and continue to support everyone from startups to some of the largest tech companies on the planet.
Our team of Flutter app developers work across iOS, Android, the web and desktop—all from the same codebase. With WebAssembly (Wasm) support, we now build desktop-class web applications that rival native software performance.
This means we can deliver your product quickly and efficiently, greatly reducing development and maintenance costs compared with native and other cross-platform technologies. Flutter's AI-ready architecture also ensures your app is prepared for intelligent features like predictive UX, computer vision, and natural language processing.
The UK's leading Flutter app development company, Foresight Mobile builds Impeller-powered cross-platform apps that deliver native performance and get you to market faster from a single codebase.
Update your app's UI instantly without App Store reviews. Our Server-Driven UI (SDUI) architecture allows your backend to define layouts, content, and styling in real-time—pushing changes to all users in seconds.
Perfect for e-commerce, media, and marketing-heavy apps, SDUI enables A/B testing at scale, instant promotional updates, and consistent UI across all platforms. Your marketing team can launch campaigns without waiting for developers.
Flutter's Dart FFI (Foreign Function Interface) enables seamless integration with AI and machine learning models. Run TensorFlow Lite and MediaPipe models directly on-device for real-time computer vision, predictive text, and intelligent features—without cloud latency or costs.
For cloud AI, we integrate Google's Gemini, OpenAI GPT-4, and custom LLMs to build generative UIs that adapt to user intent. From intelligent search to context-aware recommendations, we build apps that are smart by default.
Go beyond mobile with Flutter's WebAssembly (Wasm) powered web support. With the same codebase used for your mobile app, we craft desktop-class web applications that feel native and powerful—not just responsive websites.
Wasm compiles Dart to binary code that runs at near-native speeds in the browser, enabling complex dashboards, data visualization tools, and enterprise SaaS applications. Flutter also targets Windows, macOS, and Linux natively, creating a true ambient computing platform.
There's no need to worry that your app won't feel at home compared with natively-developed apps. Flutter provides native widgets for iOS and Android through the Cupertino and Material 3 widget sets—over 700 pre-built components.
These widgets are built into the platform, allowing us to provide user interfaces that match the design idioms of each platform. Your iOS users get the iOS experience they expect; your Android users get Material Design 3—all from the same codebase.
Flutter's revolutionary Impeller rendering engine eliminates the shader compilation jank that plagued earlier cross-platform solutions. Using ahead-of-time (AOT) shader generation with Metal on iOS and Vulkan on Android, your app delivers deterministic 60-120fps animations from the first frame.
Unlike React Native's JavaScript bridge, Dart compiles directly to native machine code—extracting the full performance from your device. This means your users get a truly native experience that's indistinguishable from SwiftUI or Jetpack Compose apps.
Deploying one codebase across all platforms is inherently 40% faster than developing the same app multiple times. This cross-platform efficiency is Flutter's key business benefit.
Features like hot reload allow our developers to iterate quickly on features and see changes in milliseconds. By leveraging technologies like bloc and clean architecture we ensure that our apps are straightforward to develop and maintain, reducing technical debt from day one.
“They’re more thoughtful than any other development team I’ve worked with..... I’m not sure what they could improve."
"The team has delivered exactly what we asked for but is able to use their own skill and judgment to make improvements"
"Foresight Mobile effectively and promptly met our needs. They were a candid, reliable, and collaborative partner."
Yes, with Server-Driven UI (SDUI) architecture. SDUI allows your app to receive UI definitions from your server, enabling instant updates to layouts, content, and styling without submitting a new binary to the App Store or Play Store.
How it works: Your app becomes a rendering engine that interprets JSON-based UI definitions from your backend. Change the banner text, reorder the homepage, or launch a promotion—all users see changes instantly.
Best for: E-commerce apps needing frequent promotional updates, media apps with dynamic content, and any app requiring rapid A/B testing. SDUI is particularly valuable for marketing-heavy apps where the 48-hour App Store review cycle creates bottlenecks. However, business logic changes still require traditional app updates.
Impeller is Flutter's revolutionary rendering engine that replaced the previous Skia-based renderer. It fundamentally solves the "shader compilation jank"—the stutters that occurred when complex animations first ran—that was Flutter's historical weakness.
Impeller uses ahead-of-time (AOT) shader compilation, meaning all graphics instructions are pre-compiled before your app launches. It leverages modern low-level graphics APIs: Metal on iOS and Vulkan on Android, achieving the same GPU efficiency as native SwiftUI and Jetpack Compose apps.
The result: deterministic frame rates from the first frame, smooth 120Hz animations on capable devices, and performance that's truly indistinguishable from native apps. This is why we can confidently say Flutter delivers "native performance"—not "near-native."
We adhere to a rigorous quality assurance process, including AI-powered automated testing, comprehensive test coverage across devices, and continuous integration pipelines. Our QA process includes performance profiling, security penetration testing, accessibility compliance (WCAG 2.2), and real-device testing on our device lab to ensure each app meets the highest standards of performance, security, and user experience.
Maintaining an iOS app is an ongoing investment. Generally, maintenance costs range from 15-25% of the original development cost annually. Budget £2,000-£5,000/month for comprehensive app maintenance in 2025.
iOS maintenance costs are typically 40-50% lower than equivalent Android applications due to iOS's consistent hardware ecosystem and predictable update cycles. Swift 6 applications have even lower maintenance requirements due to compile-time crash prevention eliminating entire categories of bugs.
Free apps can generate substantial revenue in 2025 through diverse strategies including in-app advertising, in-app purchases, subscription models, freemium upgrades, and AI-powered premium features. The subscription economy has matured. Weekly subscriptions and models offering "psychological safety" (easy cancellation, clear value) now outperform rigid annual plans.
We offer Revenue Engineering services: building dynamic paywalls for A/B testing, implementing "win-back" flows for churned users, and engineering flexible subscription tiers. This positions us as partners in revenue generation, not just development costs.
The cost of building an app in the UK varies based on:
At Foresight Mobile, we understand every project has a unique budget. We offer tailored solutions including strategic code audits from £5,000 as entry points, with transparent fixed-price estimates during discovery sessions.
Foresight Mobile can assist you with publishing to numerous Android stores worldwide in 2025. These include manufacturer stores: Samsung Galaxy Store (500M+ users), Amazon Appstore, Huawei AppGallery (580M+ users), Xiaomi GetApps, OPPO App Market, and Vivo App Store. For China, we support Tencent MyApp, Baidu Mobile Assistant, and 360 Mobile Assistant. Alternative stores include F-Droid for open-source apps, Aptoide, and APKPure. The EU's Digital Markets Act now requires support for third-party stores, making alternative distribution more viable than ever.
Development timelines in 2025 have been optimised through Swift 6 efficiency and improved frameworks: MVP/Prototype takes 4-8 weeks, Simple Apps 2-3 months, Medium Complexity 3-5 months, Complex Apps 5-8 months, and Enterprise Solutions 8-12+ months. Strategic code audits complete in 1-2 weeks.
Flutter 3.x with the Impeller rendering engine is excellent for most app development projects in 2025. With Dart 3.9 and AOT shader compilation, Flutter delivers truly native performance with deterministic 60-120fps animations—eliminating the "jank" that plagued earlier versions.
Key advantages include: single codebase for iOS, Android, Web, Windows, macOS, and Linux; hot reload for instant development feedback; over 700 Material 3 and Cupertino widgets; 40% faster development than native; strong community with 1M+ developers; and enterprise adoption by BMW, Alibaba, and eBay. Flutter is ideal for MVPs, e-commerce apps, SaaS platforms, and AI-powered applications. Consider native development only when requiring deep OS-level integration or platform-specific hardware features.
Flutter requires coding in Dart 3.9, Google's modern, strictly-typed programming language. While Flutter provides over 700 pre-built widgets and AI coding assistants like GitHub Copilot and Cursor can generate boilerplate code, developers still need to write Dart code for business logic, state management, API integration, and custom functionality.
Low-code Flutter platforms like FlutterFlow allow visual development with minimal coding, but understanding Dart remains essential for professional app development. The good news: Dart is considered one of the easiest languages to learn, with syntax familiar to JavaScript, Java, and C# developers.
We employ comprehensive monitoring using industry-leading tools and AI-powered analytics including Firebase Crashlytics, Performance Monitoring, Google Analytics 4, and advanced APM tools. Swift 6's strict concurrency delivers 99.9% crash-free sessions, and we maintain 99.9% uptime SLAs through 24/7 monitoring.
Publishing costs in 2025: Google Play requires a one-time $25 fee, while Apple App Store charges $99 annually ($299 for enterprise). However, the real costs lie in preparation: app store optimization (£1,000-3,000), localization for global markets (£500-1,500 per language), promotional materials and app previews (£2,000-5,000), and legal compliance documentation (£500-2,000).
Both stores take 15% commission on small businesses (<$1M revenue), then 30%. Consider ongoing costs: ASO tools subscription (£100-500/month), review management, update submissions, and seasonal marketing campaigns. We provide complete publishing services including store listing optimization, screenshot creation, and submission management to maximize your app's success.
Modern app hosting in 2025 leverages cloud platforms for scalability and reliability. Firebase remains popular with generous free tiers: 10GB storage, 1GB Firestore, 125K Cloud Function invocations monthly. Paid plans start at £20/month. AWS Amplify offers competitive pricing from £15/month, while Google Cloud Platform and Azure provide enterprise-grade solutions from £50/month.
Typical hosting costs for production apps: small apps (< 10K users) £50-200/month, medium apps (10K-100K users) £200-1,000/month, large apps (100K+ users) £1,000-5,000+/month. Additional services like CDN (£50-200/month), real-time databases (£100-500/month), AI/ML APIs (£100-1,000/month), and backup solutions (£50-200/month) add to costs. We optimize architecture to minimize expenses while ensuring performance and reliability.
Cross-platform development in 2025 offers significant cost advantages. Using Flutter 3.x or React Native, professionally-designed apps range from £25,000-60,000 for MVPs, £60,000-120,000 for feature-rich applications, and £120,000-250,000+ for enterprise solutions. This represents 30-40% savings compared to building separate native apps.
Flutter's single codebase approach reduces development time by 40%, maintenance costs by 50%, and enables simultaneous deployment to iOS, Android, Web, and desktop platforms. Additional costs include platform-specific customizations (£5,000-15,000), native module development for advanced features (£10,000-25,000), and comprehensive testing across platforms (£5,000-15,000). The ROI improves significantly when targeting 3+ platforms.
Flutter 3.x development in 2025 is significantly faster than traditional approaches. Simple apps with standard UI components take 3-6 weeks. Medium complexity apps with custom animations, API integrations, and state management require 6-12 weeks. Complex applications with real-time features, offline sync, and advanced functionality need 12-20 weeks.
Flutter's advantages include: hot reload for instant UI updates, extensive widget library reducing custom development, single codebase for multiple platforms, and AI-assisted development tools. Factors affecting timeline: design complexity, backend development, third-party integrations, testing requirements, and App Store/Play Store approval (1-2 weeks). Our agile process with 2-week sprints ensures predictable delivery and continuous progress visibility.
Cross-platform app development in 2025 means creating applications that run seamlessly across multiple operating systems and devices from a single codebase. Modern frameworks like Flutter 3.x, React Native, and Kotlin Multiplatform enable deployment to iOS, Android, Web, Windows, macOS, Linux, and even embedded systems.
Benefits include: 40-60% cost reduction compared to native development, faster time-to-market, consistent user experience across platforms, simplified maintenance with single codebase, and unified analytics and backend. Cross-platform tools now support platform-specific customizations, native performance through compiled code, access to device APIs, and modern UI paradigms. The approach is ideal for most business applications, with native development reserved for platform-specific features or maximum performance requirements.
Flutter uses Dart 3.9 (2025), Google's modern programming language optimized for UI development. Dart offers sound null safety preventing null reference errors, fast compilation to native ARM/x64 code, hot reload for instant development feedback, and async/await for elegant asynchronous programming. Recent improvements include pattern matching, records for multiple return values, and enhanced performance with up to 2x faster execution.
Dart's syntax is familiar to JavaScript/TypeScript developers, making it easy to learn. It supports both ahead-of-time (AOT) compilation for production performance and just-in-time (JIT) compilation for development flexibility. The language includes modern features like mixins, extension methods, and sound type system. With over 35,000 packages on pub.dev, Dart's ecosystem provides solutions for virtually any development need.
