Frequently Asked Questions
Is cross-platform development performance truly as good as native?
For the vast majority of applications, yes. Modern cross-platform frameworks have made incredible strides. Flutter compiles to native code and uses its own rendering engine, often resulting in performance that is indistinguishable from native apps. .NET MAUI uses native UI controls directly, ensuring native performance for UI interactions. While older versions of React Native had performance concerns due to the JavaScript bridge, its new architecture has significantly minimized these bottlenecks, making it more than capable for even demanding applications.
Will my app have a 'native' look and feel?
This depends on the framework you choose. .NET MAUI and React Native are designed to use the host platform's native UI components, so your app will automatically look and feel like an Android app on Android and an iOS app on iOS. Flutter takes a different approach, providing a comprehensive set of widgets that can be customized to either mimic the native look (Material Design for Android, Cupertino for iOS) or create a completely custom, brand-centric design that is consistent across all platforms.
How do I choose if I don't have an existing developer team?
This is an ideal scenario to engage with a technology partner like CIS. Without legacy constraints, we can help you select the absolute best framework for your product's specific goals. We provide dedicated cross-platform app development frameworks teams (PODs) with vetted experts in all leading technologies. This allows you to start immediately with a world-class team without the overhead and time commitment of hiring and training.
What is the total cost of ownership (TCO) for a cross-platform app?
TCO extends beyond the initial development cost. It includes long-term maintenance, updates for new OS versions, bug fixes, and feature enhancements. Cross-platform development inherently lowers TCO by reducing the codebase you need to maintain by roughly 50%. Factors that influence TCO include developer salaries (which can vary by language popularity, e.g., JavaScript vs. Dart) and the efficiency of your development partner.
Are there limitations to cross-platform development?
While the gap is closing, some limitations can still exist. Applications that require extremely heavy computational processing (like high-end mobile games), deep integration with specific OS-level features (like certain background processing modes), or use of the very latest, platform-specific APIs might still be better suited for native development. However, for over 95% of business and consumer applications, modern cross-platform frameworks are a strategically sound and highly effective choice.
