The Ranges, Without the Hedging
React Native app costs vary by a factor of 8 or more depending on what you are building. Here are honest ranges based on real project scope, not the minimum numbers agencies quote to win the work and then scope-creep upward.
- Simple MVP (3 to 5 screens, basic auth, REST API consumption): $15,000 to $30,000
- Medium app (offline support, audio, background tasks, push notifications, 8 to 15 screens): $35,000 to $70,000
- Complex app (healthcare data, real-time features, multiple native integrations, compliance requirements): $60,000 to $120,000+
BeSound, a mental health audio application built for Felix Schoeller, was delivered in 6 weeks at the lower end of the medium range. The scope was tight and the requirements were well-defined before development started. That combination keeps cost down more than any other factor.
What a Simple MVP Looks Like
At the $15,000 to $30,000 tier, you are getting: user registration and login (email/password plus one OAuth provider), 3 to 5 core screens with navigation, integration with a single backend API, basic push notifications, and App Store and Google Play submission. The UI uses standard React Native components or a UI kit, not a fully custom design system. The backend is simple and either pre-existing or included as a minimal REST API.
This tier works for: investor prototypes, internal tools with mobile requirements, early-stage startups validating a single core workflow, or apps that extend an existing web platform to mobile.
What Drives Cost Into the Medium Tier
Several requirements push a project from simple to medium complexity:
- Offline support. An app that works without a network connection requires local storage, sync logic, conflict resolution, and partial download management. None of this is difficult individually, but together they add 2 to 4 weeks of engineering work.
- Audio playback. Background audio on both iOS and Android requires native entitlement configuration, lock screen controls via React Native Track Player, and progressive download management. This was BeSound's core complexity.
- Background tasks. Any processing that must continue when the app is in the background requires foreground services on Android and background fetch entitlements on iOS, each with their own constraints and review requirements.
- Custom design system. A fully custom UI with branded components, custom animations, and pixel-perfect design takes significantly longer than using a standard component library like React Native Paper or NativeBase.
What Defines Complex App Territory
Complex apps in the $60,000 to $120,000+ range share a cluster of characteristics:
- Full iOS and Android parity for complex native features (camera, biometrics, Bluetooth, health kit integration) where the platforms diverge significantly
- Healthcare data requirements (HIPAA compliance, encrypted local storage, audit logging, data deletion workflows)
- Real-time features using WebSockets that must work correctly across network transitions and app backgrounding
- App Store compliance work for apps in regulated categories (healthcare, finance, children's apps) where review is more thorough and rejections more common
- Multiple native module integrations (Stripe, video playback, augmented reality, device hardware) each requiring platform-specific native code
The App Store Submission Cost
App Store and Google Play submission is not a one-afternoon task for apps in regulated categories or with complex functionality. Apple's review process for healthcare apps, apps that handle payments, or apps with user-generated content can require multiple review rounds, guideline explanations, and policy documentation. Budget one to two weeks for submission and initial review, more if you expect rejection.
How to Control Cost
The single most effective way to control React Native development cost is to define the scope precisely before development starts. A list of screens with wireframes, a defined backend API (or existing API documentation), and a prioritized feature list reduce estimation uncertainty and prevent the scope creep that turns $30,000 projects into $60,000 projects.
Using Expo's managed workflow for the initial build is also a meaningful cost reduction. Expo handles build infrastructure, OTA updates, and over 50 common native APIs without requiring a Mac to build iOS apps. For projects where Expo's managed workflow covers the requirements, it saves 2 to 3 weeks of native build configuration work.
