How it works
Three steps from call to launch
- 1
Free call and fixed quote
Book a free call during US hours (Mon–Fri, 9 AM – 6 PM ET). Kwebby lists your screens, device features and integrations, then sends a fixed quote with milestones.
- 2
Test builds at every milestone
You pay 10% to start. Kwebby sends a test build to your iPhone or Android phone at each milestone, and you approve it in the client portal. The 40% payment is due at the midway milestone.
- 3
Store release and handover
Kwebby submits the app to both stores under your developer accounts and hands over the code and build setup. You pay the final 50% on delivery and own 100% of the code.

Why choose a React Native app development company
A React Native app development company builds one app that runs on both iOS and Android. React Native renders real native components, so the app looks and feels native on each platform.
One codebase means one build, one test cycle and one team. You launch on both stores at the same time, and every new feature reaches all users together.
Kwebby builds React Native apps with TypeScript and Expo. This setup gives fast builds, reliable updates and a codebase that any React Native developer can pick up later.
React Native vs native vs Flutter
React Native uses JavaScript and TypeScript, the same languages as React on the web. Teams with a web app can share business logic, API code and developers across web and mobile.
Native Swift and Kotlin apps fit products with heavy 3D graphics or features that need new platform APIs on release day. They cost more because each platform needs its own code.
Flutter also builds cross-platform apps, but it uses the Dart language and draws its own interface instead of native components. Kwebby recommends React Native for most business apps and explains the trade-offs on your first call.
Hire React Native developers or a full team?
Some companies want to hire a React Native developer to join an existing project. Others need a complete app with design, backend and store launch.
Kwebby supports both. For a new app, Kwebby delivers the full project at a fixed price. For an existing React Native app, Kwebby reviews the codebase and quotes each fix or feature as a fixed-price milestone.
Either way, you work with a team that knows Expo, React Navigation, native modules and the App Store review process. You do not pay for a developer to learn on your project.
What Kwebby builds with React Native
React Native fits most business and consumer apps. Kwebby builds the app types below for startups and small businesses.
Each app connects to a backend that Kwebby builds or to your existing API. Admin panels let your team manage users, content and orders without code.
- Booking and appointment apps
- Marketplace and on-demand service apps
- Loyalty, rewards and membership apps
- Field service and inspection apps with offline mode
- Fitness, wellness and habit tracking apps
- Companion apps for existing web platforms and SaaS products
Performance, testing and app store approval
Kwebby tests every build on real iPhones and Android phones as well as simulators. Tests cover different screen sizes, slow networks and older OS versions that your users still run.
React Native's New Architecture and the Hermes engine keep startup times short and animations smooth. Kwebby profiles slow screens and fixes them before release.
Apple and Google review every app before release. Kwebby prepares privacy labels, data safety forms, test accounts and screenshots, so reviewers have everything they need.
Tech we use
Frequently asked questions
How much does a React Native app cost?
Kwebby builds React Native apps from $2,999 for up to 8 core screens, user login and a managed backend. Apps with payments, real-time chat, maps or custom backends cost more. You get a fixed quote after a free call.
Is React Native good for production apps?
Yes. Meta, Microsoft and Shopify use React Native in their own apps. It renders native components and supports native code for platform-specific features.
How long does it take to build a React Native app?
Most React Native apps take 6–12 weeks from the first call to store submission. A focused MVP can launch faster, and your quote states the timeline.
Can I hire a React Native developer from Kwebby for my existing app?
Yes. Kwebby reviews your existing codebase, lists the fixes or features you need and quotes each one as a fixed-price milestone. You keep full ownership of the code.
Can React Native apps use the camera, GPS and Bluetooth?
Yes. React Native reaches the camera, GPS, Bluetooth, biometrics, contacts and push notifications through native modules. Kwebby writes custom Swift or Kotlin modules when a library does not cover your need.
How do updates work after launch?
Kwebby ships new features through standard App Store and Google Play releases. Small JavaScript fixes can go out as over-the-air updates through Expo, so users get them without a store download.
Do I own the code?
Yes. You own 100% of the source code, design files and build configuration. Kwebby hands over the repository and store access at delivery.
