The full answer
Flutter renders its own interface, so screens look and behave the same on iOS and Android. That makes it a strong choice for brand-heavy designs, custom animations and apps where pixel-level consistency matters. It uses the Dart language, which is quick to learn but less common in existing teams.
React Native uses JavaScript or TypeScript and renders platform components. If your company already runs a React or Next.js web product, React Native lets the same engineers contribute to mobile and lets you share types, validation and business logic between web and app.
Both frameworks support native modules when you need device features such as Bluetooth, background location or payments, and both have mature ecosystems. In practice, the decision often comes down to your team's skills, your design system and how you plan to maintain the app after handover.
During discovery, Creuto reviews these factors and explains the trade-offs in writing as part of the proposal, so the choice is documented and you can revisit the reasoning later.
