Our Process
A proven methodology for delivering Cross-Platform Mobile Apps that drives real results.
Platform Assessment
We evaluate your requirements to recommend React Native or Flutter, considering team expertise, performance needs, and third-party integration requirements.
Adaptive Design
We design a UI that follows iOS and Android conventions respectively, ensuring users on each platform get a native-feeling experience.
Shared Codebase Development
We build the shared business logic, state management, and API layer, then implement platform-specific UI adaptations where needed.
Dual-Platform Testing
Testing on both iOS and Android devices to catch platform-specific issues, with automated test suites running on both platforms.
Dual Submission
We submit to both the App Store and Google Play simultaneously, handling platform-specific listing requirements and review processes.
Unified Support
Single maintenance workflow for both platforms - bug fixes, OS updates, and new features deploy to iOS and Android together.

Discuss Your ProjectCommon Questions
Answers to the questions we hear most often about cross-platform mobile apps.
React Native is ideal if your team has JavaScript/React experience or you need deep integration with existing web codebases. Flutter offers better animation performance and a more consistent UI across platforms. We recommend based on your specific situation.
For most business applications, yes. Cross-platform frameworks have matured significantly. The gap is only noticeable in graphics-intensive games or apps requiring cutting-edge platform-specific APIs. For typical business, e-commerce, and social apps, the difference is negligible.
Yes. Camera, GPS, push notifications, biometrics, file system, Bluetooth, NFC, and most device APIs are fully accessible through both React Native and Flutter. For rare platform-specific APIs, we write native bridge modules.
Typically 80-95% of the codebase is shared. Platform-specific code is usually limited to navigation patterns, certain UI components, and native module integrations.
Yes. We can rebuild existing native apps in React Native or Flutter, often reusing backend APIs and design assets. We typically recommend a phased migration rather than a complete rewrite.
React Native is ideal if your team has JavaScript experience or you need deep integration with existing web codebases. Flutter offers superior animation performance and more consistent cross-platform UI. We recommend based on your team's skills, performance requirements, and long-term maintenance strategy.
Cross-platform development typically costs 40-60% less than building separate native apps. Projects range from $25,000 for simple apps to $100,000+ for complex applications. The savings come from shared business logic, a single codebase, and unified testing across platforms.
For most business applications - yes. React Native and Flutter have matured significantly, delivering near-native performance. The gap is only noticeable in graphics-intensive games or apps using cutting-edge platform APIs. For e-commerce, social, productivity, and business apps, the difference is negligible.
