One JavaScript / TypeScript codebase, two native-feel apps. We build fast, scalable React Native apps for Android and iOS — with faster time-to-market and one team to maintain.
250+ projects delivered
React Native lets you ship Android and iOS apps from a single codebase while still using real native components, so the app feels fast and natural on every device. Gamostar is a React Native app development company that builds MVPs, marketplaces, fintech, on-demand and social apps for startups and enterprises worldwide.
Our React Native developers work with TypeScript, Redux / Zustand, React Query, native modules (Kotlin / Swift) and CI/CD, so you get clean architecture, over-the-air updates and a smooth path to Google Play and the App Store. Already have a React web team? We reuse skills, logic and API layers to save budget.

Yes. React Native powers apps at large companies and works well for most business apps, marketplaces, fintech and social products. Very graphics-heavy games are better built in Unity.
Choose React Native if your team knows JavaScript / React or you share logic with a web app. Choose Flutter for highly custom UI and animation. We help you decide after a short discovery call.
A focused MVP usually takes 8–12 weeks. Larger apps with payments, chat and admin panels take 4–6 months depending on scope.
