FREQUENTLY ASKED QUESTIONS

FAQ'S

How do cross-platform apps actually work?

Cross-platform development relies on a single codebase that can be deployed across multiple operating systems (e.g., Android, iOS). Instead of writing separate native code for each platform, developers use frameworks like React Native, Flutter, or Kotlin Multiplatform to build and compile apps that maintain near-native performance.

How much does cross-platform app development typically cost?

Costs can range between $20,000 and $65,000, influenced by factors like complexity, required features, and design depth. The number of platforms (mobile, web, desktop) and integration needs also impact the final budget. A thorough discovery phase helps establish realistic cost estimates.

How long does cross-platform development usually take?

Timelines vary based on scope, features, and clarity of project requirements. Most cross-platform apps need 3 to 6 months for planning, coding, and quality assurance. Complex functionalities—like advanced integrations or custom UI elements—may extend the development cycle.

Which frameworks are popular for cross-platform app creation?

Several frameworks dominate the cross-platform landscape:

Kotlin Multiplatform: Allows shared code for Android and iOS using Kotlin.
React Native: Uses JavaScript and React principles, supported by a large ecosystem.
Flutter: Built by Google, leverages Dart for expressive UI and quick iteration.
Xamarin: Maintained by Microsoft, uses C# for robust, native-like performance.

Are cross-platform apps as good as native apps in terms of performance?

Modern cross-platform frameworks have evolved significantly. While some edge cases benefit from native code optimizations, most business-focused apps achieve near-native performance using these frameworks. Proper architecture, optimized code, and rigorous testing ensure smooth user experiences across platforms.

How do you ensure quality and consistency across different devices?

Thorough QA practices, including automated tests and device-specific checks, help maintain consistency. We test on various screen sizes, operating systems, and hardware configurations to guarantee that your app’s functionality and design remain cohesive across all supported platforms.
