Quick answer
Flutter or React Native — which should you choose?
Both build iPhone and Android apps from one code base with near-native performance. Flutter, from Google, draws its own interface in Dart, which makes highly custom, animated designs consistent on every device. React Native, from Meta, uses native components and JavaScript or TypeScript, which suits teams that already work in React. We choose per project, based on your design, features and team.
- One code base for iOS and Android
- Near-native speed and device access
- Faster updates on both stores

Straight answers
Questions worth asking Questions worth asking
The things brands actually ask us before a build — answered properly, including the times the answer is that you do not need us.
Is Flutter better than React Native?
Neither is better everywhere. Flutter excels at custom, animated interfaces that look identical on every device; React Native suits teams already using React and apps that should look fully native. We recommend one based on your design, features and who will maintain the app.
Is a cross-platform app as good as a native app?
For most business, ecommerce and booking apps, yes — users cannot tell the difference. Native development still wins for graphics-heavy games or apps that rely on the newest platform features on day one.
How much does a Flutter or React Native app cost?
Usually less than building two native apps, because most of the code is shared. The final price depends on screens, features and back end. After a short call we send a fixed, itemised quote.
How long does a cross-platform app take?
A focused first version often takes ten to sixteen weeks for both platforms together, including design, testing and store review.
Can you take over an existing Flutter or React Native app?
Yes. We start with a code review, update outdated dependencies and fix the most important issues before adding new features.
Do you publish on both app stores?
Yes. We prepare both listings and publish through developer accounts in your name, then handle updates after launch.
