Frequently Asked Questions

Check out the most asked questions by our customers, which you may find useful, resolving your queries about our cross-platform app development services.

For most business apps, including commerce, booking, banking, and health tracking, users will not notice a difference when the app is built well. Flutter compiles Dart to native machine code, and React Native’s New Architecture removes the old asynchronous bridge between JavaScript and native code. Gaps appear in sustained 3D graphics and deep OS integrations, where we write native modules or recommend native development.

Cross-platform app development cost depends on scope, integrations, and compliance requirements. As a guide, an MVP app with core features typically costs $25,000 to $50,000, a production app with a custom backend, payments, and third-party integrations costs $50,000 to $100,000, and enterprise apps with SSO, compliance controls, and legacy system integration start costs $1.00,000 to $300,000+. Building cross-platform app usually costs less than funding two separate native apps with the same feature set.

Cross-platform apps typically take 30-40% less time than building separate native apps. An MVP typically takes 2 to 3 months, while a more complex and enterprise app can take 6 to 12+ months depending on features, integrations, design depth, and testing needs.

Choose React Native if your team already works in React and TypeScript, or you want to share code with a React web app. Choose Flutter if your product depends on a custom interface that must look identical across iOS, Android, web, and desktop. For complex apps, the deciding factors are usually your hiring market and the native SDKs you depend on, which we check during framework selection.

Yes. We audit both codebases, identify the business logic that can be shared, and migrate in phases so users never face a disruptive big-bang release. Depending on the app, that means moving screens to Flutter or React Native incrementally, or adopting Kotlin Multiplatform for shared logic while keeping native interfaces.

Kotlin Multiplatform is the stronger choice when you already run native iOS and Android apps, because you can share business logic module by module without rewriting your interfaces. Flutter is faster for a new app where one team builds every screen once. If your Android engineers already write Kotlin, Kotlin Multiplatform also avoids adding a new language to your stack.

No matter which programming language you choose for your cross-platform mobile app development, the end result always aligns with key business goals: reaching more customers and driving growth. However, you may want to opt for cross-platform app development:

  • Because you don’t want to limit to one platform
  • Because you don’t want to miss out to be the first one to market
  • Because you don’t want to make any of your users feel inferior
  • Because you don’t want to be in tech debt
  • Because you don’t want to miss out on growth

Yes, cross-platform app development is a future-proof option as it helps to save cost and time in the long term, easy to maintain, offers faster product time-to-market, seamless user experience regardless of the platform, caters to a broader audience, and even integrates seamlessly with cutting-edge technologies like AI, VR, AR, etc.

You do. The full source code, repositories, and intellectual property transfer to you under the contract, and code can live in your own repository from the first sprint.
