React Native app development services — one codebase, two app stores, native-grade performance.
Senior RN developers, TypeScript-first, Fabric renderer ready. Native modules written in-house when JS isn't enough.
From MVP to enterprise apps, we ship React Native builds that pass App Store review the first round, run at 60 FPS, and reuse logic with your React web app where it makes sense.
End-to-end React Native app development services.
From custom RN app development and native module engineering to migration, OTA delivery, and ongoing growth — everything you need to ship and operate a cross-platform mobile app.
Custom React Native App Development
Greenfield iOS + Android apps from a single TypeScript codebase — Expo or bare RN, your call. We pick based on your hardware needs, not personal preference.
Native Module Development
When JS isn't enough, we drop down to Swift, Kotlin, or C++ to write the native module — and ship it with your app, not as an afterthought.
RN Migration & Modernization
Cordova, Ionic, native iOS+Android, or legacy RN — we migrate to the latest React Native and Expo SDK, with zero feature loss.
Code Reuse with Web (React + RN)
If you already run React on the web, we share business logic, state management, and design tokens between web and RN — typically 40–60% code reuse.
Over-the-Air Updates & Deployment
Ship JS-only fixes in hours, not weeks. EAS Update or CodePush, paired with EAS Build / Bitrise for the heavy lifts.
Backend & API Integration
Mobile apps need a backend. We wire up REST, GraphQL, WebSocket, and Realtime layers — including direct integrations to Odoo, ERPNext, and Zoho.
Performance, Security & QA
RN apps that don't drop frames, leak memory, or fail OWASP — every release is profiled, audited, and tested on real devices.
AI, AR & Advanced RN Features
RN isn't a toy — push it with on-device ML, AR overlays, voice, and LLM-powered features that ship in production apps.
The React Native stack we use in production.
We work on the latest stable React Native release with the new architecture (Fabric + Turbo Modules) when your library ecosystem supports it. Stack chosen for stability first, hype second.

“They migrated us from a six-year-old Cordova app to React Native in 11 weeks. We kept every feature, gained dark mode and biometric auth, and crash-free sessions went from 96.4% to 99.8%.”

How a React Native engagement runs.
Discovery & feasibility
Days 1–5Workshops, feature mapping, Expo vs bare decision, native-module risk assessment, and a written SOW with milestone plan.
Design & system
Week 2–3Figma flows for iOS and Android, RN-specific UX patterns, and a shared design system aligned with your web app if applicable.
Build sprints
Week 3–9Two-week sprints, demos on real iPhone + Android each Friday, CI/CD with EAS Build wired up before the first PR merges.
Hardening
Week 9–10FlashList migration, Hermes profiling, OWASP MASVS pass, Detox E2E suite, and real-device matrix testing (iOS 15+ / Android 8+).
Submit & rollout
Week 10–11App Store + Play Store submission, ASO copy and screenshots, staged rollout to 10% → 50% → 100% with crash gates.
Run & evolve
OngoingOTA updates via EAS Update for JS-only fixes, monthly OS-version compatibility checks, and quarterly feature releases.
Why teams hire iVentureTeam for React Native.
Most RN shops ship JS-only code on the legacy bridge. We ship Turbo Modules and native code when the app needs it — and stick around to support the result.
New-architecture native
We ship on the Fabric renderer and Turbo Modules — the perf gap with native is now under 5%. Most RN shops still ship the legacy bridge.
Expo or bare — your call
We don't push managed Expo as a one-size-fits-all. If your app needs custom Bluetooth, MDM, or CarPlay, we bare-eject. If not, we keep you on EAS.
Native modules when needed
We write Swift, Kotlin, and JSI code in-house. If a library doesn't exist, we build the module — and own it long-term.
Web + mobile code reuse
If you run React on the web, we share 40–60% of business logic, types, and design tokens. One PR fixes two platforms.
OTA hot-fix discipline
EAS Update or CodePush configured day one. A JS-side bug ships in 30 minutes, not a 5-day App Store wait.
Real-device QA matrix
We test every release on a documented matrix of devices — old iPhones, low-RAM Android, foldables. Sentry catches the rest in production.
React Native apps we build for these industries.
Frequently asked questions
Why choose React Native over native iOS / Android development?
React Native lets you ship the same app to iOS and Android from a single TypeScript codebase, typically saving 35–45% in development time and ongoing maintenance. With the new Fabric renderer, Turbo Modules, and Hermes engine, the runtime gap with native is now under 5% for most apps. Choose native only when you have deep platform integrations (ARKit, CarPlay, exotic Bluetooth profiles) or strict perf requirements (heavy graphics, real-time camera processing).
Should I use Expo or bare React Native?
Expo is the right default for 80% of apps — faster dev loop, EAS Build, OTA updates, and an excellent module ecosystem. Choose bare RN (or Expo Prebuild) when you need custom native code, MDM enrollment, CarPlay / Android Auto, advanced Bluetooth, or libraries that haven't been wrapped for Expo. We make this call in week one based on your feature list.
How much does React Native app development cost?
React Native MVP builds typically range $30K–$70K for a polished single-feature-set app shipped to both stores. Feature-complete production apps land between $55K–$140K depending on backend, integrations, and native modules. A dedicated senior RN engineer is around $4,500–$6,500/month. We give a written fixed-price quote after a 30-minute scoping call.
How long does it take to build a React Native app?
Most production RN apps ship in 10–14 weeks end-to-end. A focused MVP can launch in 6–8 weeks if scope is tight. The biggest variables are backend complexity, third-party SDK integrations, and any native modules we need to write from scratch.
Do you handle React Native native module development?
Yes. When a library doesn't exist or doesn't meet our perf bar, our team writes the native module in Swift / Objective-C for iOS and Kotlin / Java for Android — exposed through JSI / Turbo Modules. Common modules we've built: custom Bluetooth profiles, MDM integration, hardware barcode scanners, CarPlay, low-level audio processing, and biometric flows.
Can you migrate our existing app to React Native?
Yes. Common migrations: Cordova or Ionic to React Native (typically 6–10 weeks), two separate native iOS + Android codebases consolidated to one RN codebase (10–14 weeks), and legacy RN (0.60-era bridge) upgraded to the new architecture with Fabric and Turbo Modules. We start every migration with a written audit so you know exactly what survives and what gets rewritten.
Do you support OTA (over-the-air) updates?
Yes — configured day one. We use EAS Update (for Expo apps) or Microsoft CodePush (for bare RN), with separate production and staging channels, staged rollouts, and automatic rollback on crash spikes. A JS-only fix can ship in 30 minutes versus a 3–5 day App Store review.
Can we share code with our React web app?
Yes — typically 40–60% code reuse. We extract business logic, API clients, data models, validation, and analytics into a shared TypeScript package. Design systems can be unified using Tamagui, NativeWind, or Restyle. One pull request fixes the same bug on web and mobile, and you keep one team across both.
What's included in your post-launch React Native support?
Every fixed-price build includes 30 days of post-launch hypercare — crash response, OS version compatibility, and minor tweaks. Beyond that, monthly retainers cover 4-hour crash SLAs, Expo SDK / RN version upgrades, native module maintenance, ASO reviews, quarterly feature releases, and OTA hot-fix support.
