Is React Native good enough for production apps?

Absolutely. React Native powers production apps at companies like Meta, Microsoft, Shopify, and Discord. With Moodify, I confirmed firsthand that performance is excellent, including complex animations powered by Reanimated. The ecosystem is mature, the community is active, and regular updates ensure a reliable framework for professional projects. The new architecture with Fabric and TurboModules has closed the remaining performance gaps.

React Native or Flutter: which should I choose in 2026?

It depends on your context. React Native is ideal if your team already knows JavaScript or TypeScript, if you need to integrate existing native modules, or if you want access to the massive npm ecosystem. Flutter is a strong choice if you are starting from scratch, targeting web and desktop as well, or prefer Dart. In 2026 both frameworks are mature and performant. Personally, my deep experience with the JavaScript ecosystem made React Native the clear choice for Moodify.

How long does it take to build an app with React Native?

For Moodify, the full development took about four months working solo. A simple app can be built in six to eight weeks, while a complex project with a backend, authentication, and advanced features can take three to six months. Using Expo significantly accelerates the initial setup and prototyping phase. The biggest time sinks are usually not the code itself but UX iterations and app store compliance.

Can a single developer build a complete mobile app?

Yes, it is entirely possible with React Native, especially when using Expo which drastically simplifies the workflow. I built Moodify solo, from design to app store publication. However, be realistic about timelines and prioritize features for an MVP. I also recommend bringing in a UX designer at least for a review pass to validate your interface decisions, even if you handle the rest yourself.

How much does it cost to build a React Native app?

Costs vary widely depending on complexity. For an app like Moodify built by a freelance developer, expect between eight thousand and twenty thousand euros. An agency will typically charge between twenty thousand and sixty thousand euros. The main cost drivers are development, UX/UI design, Apple and Google developer accounts (99 and 25 euros per year respectively), and potentially backend hosting. React Native saves roughly thirty to forty percent compared to developing separate native iOS and Android apps.
