L'excellence numérique au cœur de Paris. We build production-grade cross-platform mobile applications with React Native. Share 85-95% of code between iOS and Android while maintaining native performance, platform-specific UX, and access to device APIs — at 40% lower cost than dual native development.
Paris is home to Station F and a dense startup scene supported by the La French Tech program, alongside luxury, insurance and banking groups. French buyers expect GDPR compliance enforced by the CNIL, French language interfaces, and the legal notice pages French law requires on every site.
Native French-speaking team with deep knowledge of RGPD compliance, the French startup ecosystem (Station F, BPI France), and luxury/fashion industry digital transformation.

Many Paris founders need to be on both the App Store and Google Play from the first release but cannot fund two native teams. React Native answers that, and it fits well when the company already uses React for its web product, because developers and some logic can move between them.
The trade-offs are worth understanding. Most screens, forms and lists work well cross platform. Heavy animation, complex Bluetooth or camera work may need native modules, which adds effort. Over-the-air updates let you fix JavaScript bugs without waiting for store review, within the limits Apple and Google allow. Whatever the framework, GDPR consent must be collected before analytics SDKs start, and the CNIL's mobile guidance applies equally.
Ask a provider which parts of your app they expect to need native code, and how they keep React Native and its libraries upgraded, since lagging versions create real maintenance cost. Ask to see a release pipeline. Cost depends on feature depth and the backend more than on the framework choice. Check that the provider has shipped React Native apps that are still maintained today, not only demo projects. Ask how they test on both platforms before each release, and whether automated tests run on every change. Budget for the store listings, review processes and annual platform updates that come with any mobile app.
