Whether you're choosing between Flutter and React Native, modernizing a legacy hybrid app or scaling a cross-platform product across millions of users, our cross platform app development services cover every layer of the stack, from framework strategy to AI integrated app development that makes your product genuinely smarter with every release.
The wrong framework decision is the most expensive mistake in cross-platform. We help product and engineering leaders pick between Flutter, React Native, Kotlin Multiplatform and going native, based on your team, your roadmap, your performance requirements and your AI integration goals. Honest recommendations, documented decisions and a strategy that holds up two years from now, not just two sprints.
A cross-platform app done right doesn't feel like a compromise, it feels native on every device it touches. We build production-grade applications on Flutter and React Native (and Kotlin Multiplatform when the use case fits), engineered for 60fps performance, platform-aware UI and the kind of shared-code economics that justify the choice in the first place. One codebase, native quality, real engineering velocity.
Speed-to-validation is where cross-platform genuinely changes the math. We help founders and product teams ship dual-platform MVPs in 8 to 14 weeks, using a pragmatic mix of framework velocity, AI-assisted code generation and a tight feedback loop that gets your app into real users' hands before your runway dictates the roadmap. Built to learn fast, refactor cleanly and scale into the production architecture that comes next.
If you've inherited an Ionic app held together by patches, a Cordova product the rest of the team won't touch or an early-era React Native or Flutter app that's accumulated five years of architectural debt, you have two real choices: refactor or rebuild. We audit honestly, recommend pragmatically and migrate incrementally, so your active roadmap doesn't stall while we modernize the foundation underneath.
Cross-platform sits in a unique position for AI integration. One codebase means one AI integration ships everywhere at once, and modern frameworks bridge cleanly to on-device intelligence through Core ML, ML Kit, TensorFlow Lite and MediaPipe. As an AI integrated app development company, we wire intelligence into the architecture from day one. Streaming LLM interfaces, agent workflows, vector search, RAG over your data and on-device inference, all from a single codebase.
A cross-platform app that ignores platform conventions ends up feeling foreign on both iOS and Android. Our designers ship in Figma and validate in real builds on both platforms, working directly with engineers to deliver interfaces that respect Apple's Human Interface Guidelines and Material Design 3, while sharing the design system underneath. The translation loss between design and code that defines most cross-platform projects doesn't happen here.
Cross-platform frameworks move fast. Flutter ships major SDK releases every few months, React Native's New Architecture changes the underlying engine, and both Apple and Google tighten their platform policies on their own schedules. Our maintenance engagements keep your cross-platform app current with framework upgrades, dependency hygiene, OS releases and store policy changes, so you don't wake up to a broken production app the day the next major version ships.
Most cross-platform apps treat AI as a server-side bolt-on that lives behind a loading spinner. We treat it as a first-class architectural decision, running where it should run, whether that's an OpenAI endpoint, an on-device Core ML model on iOS or Gemini Nano on Android. Every layer below is engineered as a native part of the product, shipping consistently to every platform from one codebase.
Learns user behaviour and reshapes content, layout and features with the same intelligence layer running consistently on iOS, Android, web and desktop.

The right framework is the one that fits your team, your roadmap and your performance requirements. Not the one with the loudest marketing or the trendiest GitHub stars this quarter. Here's how we help product and engineering leaders choose, and what each path actually looks like in production.
Flutter App Development
Flutter is the right call when you need maximum UI control, pixel-perfect design parity across platforms, a single codebase that genuinely reaches mobile, web and desktop, or your team is open to investing in Dart. Backed by Google, powered by the Impeller rendering engine, and proven at scale by BMW, Alibaba, ByteDance and Google's own products.
Right for you if:
React Native App Development
React Native is the right call when your team already lives in JavaScript or TypeScript, when code-sharing with your React web stack is genuinely valuable, or when you want to leverage the JS AI ecosystem directly. Backed by Meta, proven at scale by Shopify, Discord, Coinbase and Microsoft. New Architecture and Hermes have made it more production-ready than ever.
Right for you if:
Kotlin Multiplatform (KMP)
KMP is the right call when you want to keep your iOS and Android UIs natively built (SwiftUI and Jetpack Compose), but share business logic, networking, data and AI integration layers underneath. Backed by JetBrains, increasingly adopted by Netflix, Philips, McDonald's and others. The "share what makes sense, not everything" approach to cross-platform.
Right for you if:
Going Native
Sometimes the honest answer is: don't go cross-platform. Native Swift, SwiftUI and Kotlin with Jetpack Compose remain the right choice when you need maximum platform performance, deep OS-level integrations (HealthKit, ARKit, ARCore, Apple Intelligence, Gemini Nano), or the kind of polish that earns App Store editorial features and Play Store Editor's Choice placement.
Right for you if:
We're not just another cross-platform shop. We're the AI-first engineering partner you bring in when the framework decision, the platform parity and the long-term maintainability actually matter. Most agencies push the framework they know. We recommend the one that fits your product.
Flutter, React Native, Kotlin Multiplatform and native Swift and Kotlin. Our engineers live in multiple ecosystems, not just one. The recommendation is yours, the depth is real.
You get engineers who've shipped real cross-platform apps at scale, navigated framework migrations, debugged production rendering issues and survived major SDK upgrades. Not juniors learning a framework on your roadmap.
We architect for what's coming. Impeller, Fabric and TurboModules, AI-native abstractions, evolving platform policies, and the next generation of cross-platform frameworks. Not just what shipped at the last conference.
Fast cross-platform delivery is the whole point. We move quickly because our architecture is clean, our types are tight and our CI catches problems before they ship, not because we're cutting the corners that matter.
We push back when cross-platform won't work and recommend going native when it's the right call. You hire a thinking team, not an order-taker, not a framework evangelist.
Clear sprints, honest status, no surprise invoices. You always know what's shipping to TestFlight and internal testing, what's blocked and what it costs.
Most cross-platform project failures aren't technical, they're process failures that surface as framework regret six months in, platform parity bugs at launch, performance issues in production or a codebase no engineer wants to inherit. Our cross platform app development services follow a structured, AI-assisted delivery methodology designed to surface problems early when they're cheap to fix and maintain engineering quality from the first commit to post-launch support.
Here's exactly how it works.
We understand your business goals, your target users, your team's technical depth and your existing tech stack. Then we recommend a framework, Flutter, React Native, KMP or native, with the trade-offs documented honestly.
We gather, analyze and prioritize functional and technical requirements with cross-platform-specific constraints. Platform parity expectations, native integration needs and code-sharing opportunities accounted for from day one.
We design platform-aware, cross-platform interfaces that respect both iOS and Android conventions and deliver experiences that feel genuinely at home on each.
Our agile teams build high-quality, scalable and maintainable code in iterative sprints, with internal builds shipping to TestFlight and Google Play internal testing continuously.
We ensure reliability, security and performance through framework-native testing tools and AI-generated test scenarios that validate behaviour consistently across both platforms, not just on the device the developer happened to be holding.
We use Fastlane, EAS Build, Codemagic and CI/CD pipelines for fast, secure and seamless dual-store deployments, with code-signing handled automatically and over-the-air updates wired in where they make sense.
We provide continuous monitoring, framework upgrades and feature enhancements to help your cross-platform app keep pace with both Apple and Google release cycles, plus the framework's own upgrade cadence.
Your cross-platform project doesn't fit a template and your engagement shouldn't either. The right way to hire cross platform app developers depends on your scope, your roadmap and your budget reality. Three models, all built for AI-era delivery speeds.
You're building a complex cross-platform product over six months or more, your roadmap is still evolving, or you need to scale your in-house team without the cost and lead time of full-time hires.
Hand-picked engineers, a QA specialist and a technical lead all working only on your product. Sprint planning, standups and retros run on your calendar, your tooling, your definition of done. AI-assisted engineering is built into how the team ships, not bolted on later.
Monthly retainer. No surprise invoices, no scope-creep billing. Team composition flexes as your roadmap demands.
3 to 12 engineers
6-month minimum
Scales with 30-day notice
Most mid-market companies start with one and evolve into another as their product matures. Let's figure out the right starting point together.
Building AI Integrated Cross-Platform Apps for the Businesses That Will Define the Next Mobile Decade. The companies that invest in intelligent cross-platform products now won't need to catch up when AI-native mobile becomes the table stakes everyone else is scrambling for.
Cross-platform earns its place in industries where time-to-market, dual-platform parity and engineering velocity decide who wins, which is exactly why these verticals trust us as their best cross platform app development company partner.
Honest answers to the questions every founder, product owner and engineering leader asks before they choose the best cross platform app development company for their build. If something isn't covered here, our solution architects will walk you through it on a discovery call, no sales pitch, no fluff.
Look beyond the portfolio. The right cross platform app development company asks more questions than it answers in the first conversation, about your team, your existing tech stack, your platform parity expectations and what going cross-platform would actually cost versus going native. Evaluate on framework-agnostic thinking, communication quality and whether they push back constructively when they disagree. Anyone who recommends a specific framework before they've understood your requirements isn't the right partner.
End-to-end cross platform app development services cover framework selection, product strategy, cross-platform UI/UX design, engineering in Flutter, React Native or KMP, native module or platform channel development, third-party and AI service integrations, dual-store submission and review preparation, QA across iOS and Android and post-launch support including framework upgrades. The best engagements also include discovery and framework selection consulting before any code is written.
Flutter for maximum UI control and multi-platform reach beyond mobile. React Native when your team lives in JavaScript or you're sharing code with a React web stack. KMP when native UI quality is non-negotiable but you want to share business logic. Native Swift or Kotlin when performance is the product or deep OS integrations matter. We recommend based on your team, your requirements and your roadmap, not based on what we're trying to sell.
A focused cross-platform MVP: $25,000 to $60,000. A mid-complexity cross-platform app with backend integrations: $80,000 to $200,000. A full-scale enterprise or AI-integrated cross-platform platform: $200,000 to $500,000+. Cross-platform often delivers 30 to 40% savings versus shipping two separate native codebases, but only when the app is architected for cross-platform from day one. We won't quote a number before we can stand behind it.
Focused cross-platform MVP: 8 to 14 weeks. Mid-complexity cross-platform app with integrations: 3 to 5 months. Enterprise or AI-integrated platform: 6 to 12 months or more. Cross-platform's velocity advantage is real, but it shows up most in iteration speed after launch, not just initial build time. We provide milestone-based timelines in writing before development begins.
Three models: Dedicated Team (for long-term, evolving products), Time & Material (for iterative or exploratory builds) and Fixed Cost (for well-scoped, budget-defined projects). When you hire cross platform app developers from us, we recommend the model honestly based on your situation, not based on which one is most profitable for us.
Yes. Whether you want to hire Flutter app development company capacity, hire React Native app development company capacity or mix specialists from both ecosystems on the same project, our Dedicated Team model is built for it. Hand-picked engineers from our senior bench, embedded in your sprint cadence, accountable to your roadmap. Framework specialization without the recruiting cycle or full-time hire overhead.
AI integrated cross-platform app development means building intelligence into your product's architecture from the start, through LLM API integrations, on-device ML through native modules or platform channels, streaming AI interfaces, agent workflows and vector search, not adding chatbots as an afterthought. Cross-platform is uniquely well-positioned for AI integration because one integration ships to every platform at once. In most mid-market segments, the companies not exploring it are falling behind the ones that are.
Yes. Flutter runs in production at Google, BMW, Alibaba and ByteDance. React Native runs at Meta, Shopify, Discord, Coinbase and Microsoft. KMP is in production at Netflix, Philips and McDonald's. The question isn't "is cross-platform production-ready?", it's whether your specific product fits the cross-platform model. We have that conversation honestly during discovery.
Parity is a deliberate design decision, not a happy accident. We define platform-specific behaviour during design, where iOS conventions should rule, where Material Design should take over, where both should converge and we validate it through automated dual-platform testing on every release. The goal isn't pixel-identical apps; it's apps that feel correct on each platform while sharing the maximum amount of code underneath.
All cross-platform applications are designed for scale from the initial architecture review. Cloud-native backends, modular architecture, type-safe codebases, dependency hygiene, performance budgets enforced in CI and load testing under realistic peak conditions before launch. Your app should handle 100x your current user base without emergency re-engineering.
Security is designed in, not reviewed at the end. OWASP Mobile Top 10, certificate pinning, secure storage on both platforms via native modules or platform channels, biometric auth, mandatory penetration testing before submission, and compliance controls for HIPAA, GDPR, PCI-DSS and SOC 2 as relevant to your industry. Compliance documentation is produced as a deliverable, not an afterthought.
Yes. We conduct a technical audit first of code quality, architecture decisions, framework version status, dependency health, native bridge quality, store compliance posture and accumulated technical debt. We give you an honest picture of what you've inherited and a clear recommendation for what to do about it. Sometimes the answer is refactor. Sometimes it migrates frameworks. Sometimes the existing work is better than it looks.
Yes. Dual-store submission, review preparation, metadata optimization, screenshot generation, App Privacy and Data Safety disclosures and rejection response across both stores are all included in our cross platform app development services. We've shipped enough apps through both review processes to know what triggers rejections before they happen and how to respond fast when something does come back.
