Cross-Platform App Development — Frequently Asked Questions
Should I build native or cross-platform for my Denver startup?
It depends on your team and product. Cross-platform (React Native or Flutter) saves 30-50% on initial build cost and is excellent for apps with standard UI patterns. Native wins when you need bleeding-edge OS APIs, complex animations, or hardware access that cross-platform bridges handle poorly. After 20+ years shipping all three, the honest answer is: scope the product first, then pick the tool.
What is the difference between React Native and Flutter?
React Native uses JavaScript/TypeScript and renders to native OS components — the UI looks exactly like a native app because it uses the same widgets iOS and Android use. Flutter uses Dart and draws everything in its own rendering engine — pixel-perfect consistency across platforms. React Native has a larger ecosystem; Flutter has better performance on animation-heavy UIs.
How much does a cross-platform app cost vs. two native apps?
A single cross-platform codebase is roughly 60-70% of the cost of two separate native apps. The savings come from shared business logic, shared state management, and a single test suite. Platform-specific UI polishing and native module bridges still add time.
Can a cross-platform app access device hardware like cameras and Bluetooth?
Yes, through native modules and community libraries. Camera, microphone, GPS, BLE, push notifications, and biometrics are all available in React Native and Flutter. The caveat: native modules require per-platform implementation, which erodes cost savings if your app is hardware-heavy.
Do you convert existing native apps to cross-platform?
Yes, but only when the math is right. If you have two native codebases with diverged features, a migration to React Native or Flutter is a rewrite — budget accordingly. If you have one native codebase and need the other platform, cross-platform often beats maintaining two native trees.
