Cross-Platform App Development Services for React Native & Flutter
Cross-Platform App Development Services from our team cover React Native and Flutter builds for organizations that want one codebase serving both iOS and Android without doubling their mobile engineering investment entirely. We build custom cross-platform applications with genuine code-sharing, and we say plainly when cross-platform is the wrong call — heavy graphics or deep OS integration usually favor native development instead in those specific cases entirely and quite clearly. Talk to our mobile engineering team about your app and requirements.
Cross-Platform Frameworks We Build With
Cross-platform development today centers on React Native and Flutter, two genuinely different approaches to the same overall goal: sharing one codebase across iOS and Android while still delivering an experience that feels native to each platform's own users, connecting to whatever web application backend already powers your product. We build with whichever framework genuinely fits your team and app requirements best, without bias. We help teams evaluate this tradeoff honestly rather than defaulting to whichever framework happens to be currently trending in the market.
React Native
React Native shares JavaScript and React knowledge with web development teams, letting organizations with existing React talent extend into mobile without hiring an entirely separate iOS and Android engineering team from scratch entirely.
Flutter
Flutter uses Dart and renders its own UI layer rather than using native components, giving highly consistent visual results across platforms at the cost of a less familiar language for most existing web development teams.
Native Development
Native development in Swift and Kotlin remains the right choice for apps needing deep OS integration, cutting-edge platform features, or graphics-intensive performance that cross-platform frameworks cannot fully replicate on both platforms equally well.
React Native vs Flutter vs Native Decision
Choosing between React Native, Flutter, and native development depends on your team's existing skills, your app's specific technical requirements, and how much of the codebase genuinely needs to be shared versus platform-specific right from the very start. We scope this honestly during our discovery process with every single new client we take on. Getting this assessment right during discovery avoids costly rework later, once real device testing reveals a framework's actual limitations.
Code-Sharing With React Native
React Native typically achieves 70 to 90% code sharing between iOS and Android for standard business applications, with the remainder being platform-specific native modules for camera, notifications, or other device-specific features and hardware.
Code-Sharing With Flutter
Flutter often achieves even higher code-sharing percentages since it renders its own UI rather than relying on native platform components, though this comes with a steeper learning curve for teams unfamiliar with Dart specifically as a language.
Matching the Framework to Your Team
Teams with existing React or JavaScript expertise usually see faster ramp-up with React Native, while teams starting fresh with no strong framework preference often find Flutter's consistency easier to maintain over the long term.
When Cross-Platform Is the Wrong Call
Cross-platform is genuinely the wrong call for some apps, and saying so plainly here is more useful to a buyer doing real research than a page that pretends cross-platform always works regardless of your app's actual technical requirements and constraints. We say this honestly upfront, well before any contract is ever signed. Being upfront about these limitations during discovery is what earns lasting trust with clients evaluating multiple development partners seriously.
Heavy Graphics & Games
Apps with heavy graphics needs — games, AR/VR experiences, complex data visualization — usually perform better built natively, since cross-platform frameworks add a rendering layer that introduces real performance overhead for graphics-intensive work specifically.
Deep OS Integration Needs
Apps needing deep OS integration — background processing, specific hardware sensors, or cutting-edge platform features released before cross-platform framework support catches up — are usually better served by native development from the very outset.
Why Choose Us for Cross-Platform Development
Working with a cross-platform development partner should mean an honest assessment of whether cross-platform actually fits your app, not a default recommendation toward whichever framework the agency happens to specialize in regardless of the actual fit involved. We assess this honestly for every single client engagement we ever take on. That honesty during discovery is what prevents a costly framework mismatch from surfacing only after significant development work is done.
Connected Backend APIs
We connect cross-platform mobile apps to backend APIs we build in parallel, ensuring your mobile and backend teams work from the same shared data contracts and integration patterns throughout the entire development process.
An Honest Framework Recommendation
Our discovery process includes an honest framework recommendation based on your specific app requirements, not a default push toward whichever framework happens to be the one our team simply prefers building with most often.
Frequently Asked Questions
Should we choose React Native or Flutter for our app?
React Native suits teams with existing React or JavaScript expertise wanting faster ramp-up on the project. Flutter often achieves higher code-sharing and visual consistency but has a steeper learning curve overall. We help scope which fits during an initial discovery conversation together.
What percentage of code can actually be shared between iOS and Android?
Typically 70 to 90% for standard business applications using React Native or Flutter, with the remainder being platform-specific modules for cameras, notifications, or other device features. Highly custom or graphics-heavy apps tend to see notably lower percentages overall in practice.
When should we build natively instead of cross-platform?
When your app needs heavy graphics performance, deep OS integration, or cutting-edge platform features not yet supported by cross-platform frameworks currently available. Games, AR/VR apps, and apps needing extensive background processing usually favor native development instead of a shared codebase.
How long does it take to build a cross-platform app?
A focused business application typically takes 4 to 6 months from discovery to launch. A full-featured consumer app with complex features and third-party integrations usually runs 7 to 12 months, depending on platform-specific customization needs and overall integration complexity involved.
What does custom cross-platform app development typically cost?
Costs range from roughly $50,000 for a focused business app to $280,000 or more for a full-featured consumer application. Our custom software development cost page breaks this down further by project scope and the overall feature set involved throughout.
