FAQ

Frequently Asked Questions

Should we build a native app or a cross-platform app?

Native gives maximum performance and platform API access. Cross-platform (React Native or Flutter) gives one codebase for both platforms, cutting development cost by 40–60%, with near-native performance for most business apps.

React Native vs Flutter — which is better?

React Native is better if your team has existing JavaScript experience or needs deep integration with a React web codebase. Flutter produces pixel-perfect UIs and strong performance. Both are production-proven at scale.

How much does a cross-platform app cost?

A simple app costs £15,000–£30,000. A mid-complexity app costs £30,000–£70,000. A complex app costs £70,000–£150,000+.

Can you rebuild our existing native apps as cross-platform to save costs?

Yes. App consolidation is a common project. We provide a cost/benefit analysis comparing rebuild cost against ongoing maintenance savings — typically 40–60% lower for a single cross-platform codebase.

Will the cross-platform app pass App Store and Google Play review?

Yes. We handle submissions for both stores. Our apps consistently pass first-submission review because we follow platform guidelines and test on real devices across multiple OS versions.
