When React Native Is the Right Call for Your App
Two native codebases means two teams and two release schedules. A feature can land on iOS three weeks before Android because the Kotlin developer was booked elsewhere. For a small business or a funded startup, that split spends budget on duplicated work that users never see.
React Native closes that gap for the large majority of business apps. Booking flows, marketplaces, patient portals, fintech dashboards, and field-service tools share most of their code across both platforms. The honest exceptions are apps whose core value depends on heavy 3D rendering or long-running OS-level background work. If yours is one of them, we will say so during scoping.

One squad owns both platforms, so keeping features in step across iOS and Android no longer needs coordination between two teams.
Shared TypeScript types, validation logic, and API clients move between web and mobile with little rework.
A single codebase gets a testable build into TestFlight and Google Play internal testing sooner.
EAS Update pushes JavaScript fixes to users without waiting on a store review cycle.

AR-first games and always-on sensor processing may justify writing the core in native Swift and Kotlin.
React Native Development Services We Cover
As a React Native development company, we run every engagement on current releases, TypeScript, and the Expo toolchain where it fits. The app you receive is one your next developer can upgrade without a rewrite.
Custom React Native Application Development
Greenfield iOS and Android apps built on React Native 0.8x with TypeScript, Expo Router or React Navigation, and a state layer sized to the product. Offline-first storage, push notifications, and deep links are scoped in sprint one.
React Native MVP Builds for Early Validation
Launch a working product in weeks through a scoped MVP development track. Core flows, analytics, and crash reporting ship first, so investor demos and early-adopter feedback run on real usage data from day one.
Native to React Native Migration
Existing Swift and Kotlin apps move to React Native screen by screen through brownfield integration. The store listing, user accounts, and ratings stay intact while the shared codebase grows underneath them.
New Architecture Upgrades for Older Apps
Apps stuck on 0.6x or 0.7x are audited for Fabric and TurboModules compatibility. Unmaintained libraries are replaced, and the app moves to a supported release before the next store deadline blocks updates.
Expo and EAS Release Pipelines
We configure EAS Build, code signing, and EAS Update channels so every merge produces signed iOS and Android builds. Critical fixes reach users as over-the-air updates with staged rollouts.
Native Modules in Swift and Kotlin
Some features need Bluetooth LE, background location, biometric auth, or a vendor SDK that has no JavaScript wrapper. For these, we write typed Turbo Native Modules over JSI and ship them inside your app.
AI Features Inside Mobile Apps
LLM chat, document scanning with on-device OCR, voice input, and personalized recommendations wired into React Native screens. API keys stay server-side and responses stream straight to the UI.
Performance Tuning and Ongoing Support
Hermes profiling, FlashList virtualization, bundle size cuts, and crash triage in Sentry improve crash-free sessions and startup time. Monthly dependency updates keep the app within one minor release of current.
Running an App Stuck Behind the Android 16 Deadline?
Google Play now requires app updates to target Android 16 (API level 36) or higher. We'll review your codebase and scope the upgrade.
Check Android ReadinessModernizing Older React Native Apps for Current Releases
A React Native app last upgraded in 2023 may still work, but older dependencies, architecture changes, and new platform requirements can make the next release harder to ship. We modernize existing React Native codebases, including apps inherited from previous vendors, and move them toward a supported release without forcing a full rewrite.
Codebase and Dependency Audit
We map packages against New Architecture support, identify outdated or abandoned libraries, and check native code for legacy patterns. You get a written upgrade plan with effort estimated by module before development starts.

Stepwise Version Upgrades
Large version jumps are handled in manageable stages rather than treated as a single rewrite. Automated tests help catch regressions throughout the upgrade so issues can be addressed before they reach production.
Android 16 and iOS SDK Updates
We address target SDK requirements, edge-to-edge behavior, screen-size changes, and other platform updates alongside the React Native upgrade, with device testing before release.

If another team built or maintained the app, we can document the existing setup, resolve missing environment configuration, rebuild CI/CD workflows, and establish a maintainable development process for your team.

Process We Follow for React Native Development
1
Discovery and Scoping
Requirements, user stories, and wireframes come before any code. As an experienced React Native development company, we identify which features need native modules, which third-party SDKs must support the New Architecture, and where offline behavior matters. The output is a scoped backlog, an architecture note, and an estimate your finance team can plan around, so the build starts with fewer unknowns.
2
UX Design for Both Platforms
Designers work in Figma with Apple's Human Interface Guidelines and Material 3 patterns side by side. Shared components carry most screens. Platform-specific touches such as back navigation, date pickers, and haptics are decided early. Clickable prototypes are tested with real users before engineering commits to the flows.
3
Architecture and Environment Setup
Engineers set up the repository structure, TypeScript config, navigation, state management, and API contracts with your backend. EAS Build profiles, signing credentials, and staging and production environments are configured in week one. That puts the first internal build on test devices early in the project.
4
Sprint Development With Weekly Demos
Two-week sprints deliver features to TestFlight and Google Play internal testing. You see working builds on your own phone every week and receive daily written updates in Slack or Teams. Pull requests pass code review and automated Jest tests before merge, which keeps the main branch releasable.
5
QA on Real Devices
Detox and Maestro run end-to-end flows in CI. Manual QA covers a device matrix that includes older Android phones, tablets, and the latest iOS release. Accessibility checks against WCAG 2.2 and performance profiling on low-end hardware catch the problems store reviewers and users notice first.
6
Store Submission and Launch
We prepare the App Store and Google Play listings, Apple privacy labels, Google Play data safety forms, and review notes. Phased rollouts start with a small percentage of users while Sentry watches crash rates. EAS Update stays ready for same-day JavaScript fixes if anything slips through.
7
Post-Launch Support
After launch, the app moves to an SLA-backed support plan covering L1 to L3 issues, monthly dependency updates, and the annual target SDK bump that Google Play enforces each August. Feature work continues on the same sprint rhythm whenever your roadmap needs it, with full context carried over from the build.

What Drives React Native App Development Cost
Feature Scope and Screen Count
A 12-screen booking app and a 60-screen marketplace with seller dashboards sit in different budget brackets. Auth, payments, chat, and admin panels each add backend work on top of the mobile screens, so the feature list drives most of the estimate. Discovery trims that list to what launch actually needs.
Backend and Integrations
Apps that connect to an existing API cost less than apps that need a new one. New backend development for auth, business logic, and admin tools can match the mobile effort itself on data-heavy products. Integrations with Stripe, Salesforce, EHRs, or ERPs add to that.
Native Modules and Device Features
Standard camera, maps, and push notifications run on maintained libraries. Custom Bluetooth hardware, background geofencing, or a vendor SDK without React Native bindings needs Swift and Kotlin work. That adds engineering time and extra QA across device models.
Compliance, Security, and Upkeep
HIPAA, PCI DSS, or SOC 2 obligations add encryption, audit logging, and penetration testing to the scope. Post-launch costs cover hosting, monitoring, and yearly SDK updates. Citrusbug includes a free maintenance period after release to cover the first stabilization window. [VERIFY: length of the free maintenance period]
How Much Does It Cost to Develop a React Native App?
Focused React Native MVPs typically start around $12,000. Multi-role apps with custom backends range from $30,000 to $100,000 or more. Share your scope for a line-item estimate.

Read Article →Questions Buyers Ask Before Hiring a React Native Team
How much does React Native app development cost?
Focused MVPs from a React Native development company usually start around $10,000. Multi-role apps with custom backends run $30,000 to $100,000 or more. Screen count, integrations, and native modules move the number most.
How long does it take to build a React Native app?
A scoped MVP typically takes 10 to 16 weeks from discovery to store release. Apps with custom backends, payments, and admin panels usually need four to eight months.
Is React Native better than Flutter in 2026?
For business apps and teams already using React on the web, React Native usually wins on code sharing, hiring, and over-the-air updates. Flutter suits heavily custom-drawn interfaces.
Can you upgrade our old React Native app to the New Architecture?
Yes. We audit dependencies, replace unsupported libraries, and upgrade in stages with automated tests at each step. Apps on 0.6x or 0.7x can usually reach a current release without a rewrite.
Is React Native a good fit for a small business app?
Usually, yes. One codebase and one team for iOS and Android lower both build and maintenance cost. Expo's tooling also removes much of the release overhead a small team would otherwise carry.
Do we own the source code?
Yes. Repositories live in your organization from the first commit, and an NDA is signed before discovery. At handover you receive the full source code, credentials, and documentation.
Can React Native handle enterprise-scale apps?
Yes. Meta, Microsoft, and Shopify run large React Native apps in production. Scale depends more on architecture choices such as offline sync, modular navigation, and backend design.
What happens after the app launches?
You can move to an SLA-backed L1 to L3 support plan. It covers crash fixes, monthly dependency updates, OS release testing, and the annual Google Play target SDK update.
