Our React Native App Development Services
We provide a complete suite of React Native app development services to cater to your diverse development needs
Cross-Platform App Development
Build iOS and Android apps from a single React Native codebase. We handle everything from architecture design to App Store and Play Store deployment. Our apps are built with performance-first architecture — optimized bridge calls, native modules where needed, and lazy loading for fast startup times.
React Native App Maintenance and Support
Post-launch support including bug fixes, OS compatibility updates (iOS and Android release cycles), performance monitoring, dependency upgrades, and feature additions. We offer flexible support plans — from on-call hours to dedicated maintenance teams.
MVP Development
Go from concept to a working app in 8-12 weeks. We use React Native's rapid development cycle to build minimum viable products that are production-ready, not throwaway prototypes. Start with core features, launch, validate with real users, then iterate.
Migration to React Native
Already have a native iOS or Android app that's expensive to maintain? We migrate existing apps to React Native — consolidating two codebases into one while preserving your existing backend, APIs, and user data.
Staff Augmentation
Extend your existing team with our React Native developers. You manage them directly, set priorities, and run standups. We handle HR, infrastructure, and backfills. Developers onboard within 48 hours and work in your timezone overlap (US Eastern/Pacific coverage available).

Why Companies Choose Tech Exactly for React Native
Quality services, strategic technology approach and remarkable customer satisfaction is what sets us truly apart
Full-Cycle Ownership, Not Just Code
We don't just write code and hand it over. Our team owns the full lifecycle: architecture, development, QA, deployment, and post-launch monitoring. You get a working product, not a codebase you need to figure out.
48-Hour Onboarding
Need developers fast? Shortlisted candidates are ready to onboard within 48 hours. No month-long procurement processes. Start with a 3-day free trial to evaluate fit before committing.
US Timezone Overlap
Our teams work with 4-6 hours of overlap with US Eastern and Pacific time zones. Daily standups, real-time Slack communication, and shared project boards on Jira or Linear. No waiting until "their morning" for answers.
New Architecture Expertise
React Native's New Architecture (Fabric renderer, TurboModules, JSI) is a fundamental shift. Our team has already shipped production apps on the new architecture — bridgeless, with synchronous native module access and improved performance.
Compliance-Aware Development
We build apps for regulated industries: healthcare, fintech, insurance. Our team understands HIPAA data handling, SOC 2 security practices, and PCI-DSS requirements at the code level, not just as checklist items.
Our Development Process
Discovery and Architecture
We start with your business requirements, not a tech stack. We map user flows, define the feature set, and make architecture decisions: Expo vs. bare React Native, state management approach, navigation structure, and native module requirements.
UI/UX Design
Mobile-first designs with platform-specific patterns: iOS Human Interface Guidelines and Android Material Design. We prototype in Figma with interactive flows before writing a single line of code.
Sprint-Based Development
Two-week sprints with working builds at the end of each. You see real progress, not just status reports. Every sprint includes code reviews, automated testing, and staging environment deployments.
Testing and QA
Automated unit tests (Jest), integration tests (React Native Testing Library), and end-to-end tests (Detox/Maestro). Manual QA across real device labs — not just simulators. We test on 15+ device/OS combinations.
Deployment and Launch
App Store and Google Play submission, including metadata optimization, screenshot preparation, and compliance review. We handle the submission process and any review rejections.
Post-Launch Support
Bug monitoring via Sentry/Crashlytics, performance tracking, OS version compatibility updates, and ongoing feature development. Support plans range from ad-hoc hours to dedicated maintenance teams.

I’m most impressed with Tech Exactly’s ability to understand our challenges and come up with options to resolve them
Tech Exactly takes the time to listen to us and offers us 3–5 different options to achieve the expected results.
With other vendors I’ve worked with, I have to spend a lot of time explaining the challenge to them, and sometimes, they still don’t understand it.

Frequently Asked Questions
A simple React Native app (5-10 screens, basic features, standard UI) typically costs $15,000-$30,000. A medium-complexity app with custom UI, third-party integrations, and backend development ranges from $30,000-$80,000. Enterprise-grade apps with complex business logic, real-time features, and compliance requirements can exceed $100,000. The exact cost depends on feature complexity, design requirements, number of third-party integrations, and whether you need backend development. We provide detailed estimates after a discovery call; no ballpark guesses.
An MVP with core features typically takes 8-12 weeks. A full-featured app with custom backend, integrations, and thorough testing takes 4-6 months. Complex enterprise apps can take 6-12 months. React Native's code reusability across iOS and Android saves approximately 30-40% development time compared to building two separate native apps.
Yes. React Native is used in production by companies including Meta, Microsoft, Shopify, Coinbase, and Bloomberg. It supports complex requirements like offline-first architecture, biometric authentication, push notifications, real-time data sync, and native module integration. For enterprise use cases, we typically recommend the bare React Native workflow (not Expo) for full native module control.
Yes. We migrate native iOS (Swift/Objective-C) and Android (Kotlin/Java) apps to React Native. The migration can be done incrementally — React Native components can coexist with native code, so you don't need to rewrite everything at once. We also migrate apps from older frameworks like Ionic, Cordova, and Xamarin. The typical migration timeline is 3-6 months depending on app complexity.
Both are cross-platform frameworks, but they differ in key areas. React Native uses JavaScript and native UI components — your app uses the actual platform buttons, text inputs, and navigation patterns. Flutter uses Dart and renders its own UI with a custom rendering engine — consistent look but not native components. React Native has a larger developer community and more third-party libraries. Flutter has better animation performance out of the box. We work with both and recommend based on your specific project requirements. See our Flutter Development Services →
Both. We use Expo for projects that benefit from its managed workflow — faster setup, OTA updates, simpler build process. We use bare React Native when the project requires custom native modules (Bluetooth, NFC, HealthKit), or specific native SDK integrations that Expo doesn't support. Many of our projects start with Expo and eject to bare only when needed.
For minor fixes and non-native code changes, we use over-the-air (OTA) updates via CodePush or EAS Update — users get the fix instantly without downloading a new version from the App Store. For native code changes, we go through the standard App Store and Play Store review process. We also handle iOS and Android OS version updates to ensure your app stays compatible with new releases.
