One team, one codebase, both app stores covered

Flutter, from Google, draws its own interface with a fast rendering engine and is written in Dart. It gives pixel-level control, very consistent visuals across platforms, and strong animation. React Native, backed by Meta, is written in JavaScript or TypeScript and renders real native components. It suits teams who already have web developers and want to share logic with a React website.

The choice rarely turns on raw speed, since both are fast enough for the large majority of business apps. It turns on three things: who will maintain the app after we hand it over, how custom the visual design is, and which native features you need. A heavily branded consumer app with rich animation often fits Flutter. A staff or commerce app tied to an existing React web product often fits React Native.

We recommend one in the scoping week with reasons in writing, and we also tell you if a fully native build is the better answer for your case.

Sharing code is not the same as sharing everything. Platform rules still differ: Apple's App Review and Google Play policies, permission prompts, push notification setup, background behavior and payment sheets all need platform-specific work. A good estimate counts the shared code at roughly three quarters of the effort, with the rest spent on platform detail, native bridges and testing on both operating systems.

Arabic needs particular care. Both frameworks support right-to-left, but custom widgets, icons that should or should not mirror, and mixed Arabic and English strings behave differently from one platform to the other. We build one design system with the rules defined once, then test it on real iPhones and Android devices, including budget handsets.

For anything involving personal data, we align consent and data handling with the Personal Data Protection Law (PDPL) issued by SDAIA. If you take payments, we integrate through a gateway that supports mada and check any financial feature against the requirements of the Saudi Central Bank (SAMA).

A cross-platform app with sign-in, a catalogue or booking flow, payments and notifications typically takes 8 to 16 weeks from signed scope to release on both stores. That is usually less total effort than two native apps for the same scope, though the saving shrinks if the app leans on many native features.

Hosting is your decision. We can deploy the backend to a Saudi cloud region to keep data in the Kingdom, aligned with the cloud rules of the Communications, Space and Technology Commission (CST) and the controls of the National Cybersecurity Authority (NCA ECC) where they apply to you.

You are not trapped. The source code is yours, built with standard project structure and tests. If you later need to move a heavy feature to pure native code, both frameworks allow it screen by screen, so you can migrate gradually instead of rewriting. Many teams start cross-platform to reach the market quickly and go native only where the data says it matters.
