React Native App Development .
iSkylar builds React Native applications that deliver a genuinely native experience on both iOS and Android, using the same JavaScript and TypeScript skills your web team already has, sharing business logic across platforms, and shipping to both stores simultaneously. With 15+ years of mobile delivery and deep React expertise across web and mobile, we build React Native apps that perform, hold up under real-world load, and are maintainable long after handover.

What We Build
Cross-Platform Consumer Apps
One React Native codebase, two stores — iOS and Android shipped simultaneously with platform-appropriate navigation, gestures, and UI conventions so each platform feels native to its users.
React Native for Web Teams
If your web product is already in React, your team knows the mental model. We extend it to mobile — sharing state management, API clients, and business logic between your web and mobile codebases to cut duplication and maintenance overhead.
Enterprise Mobile Tools
Offline-first data sync, biometric authentication, deep link handling, push notifications, MDM compatibility, and role-based access — React Native enterprise apps that IT approves and employees actually open.
Native Module Integration
When React Native's built-in APIs are not enough, we write custom native modules in Swift and Kotlin — bridging platform-specific hardware capabilities like NFC, Bluetooth, camera SDKs, or proprietary device APIs directly into your JS layer.
Performance Optimisation & Migration
Running a sluggish React Native app or a dated Expo project that has hit its ceiling? We audit, refactor, and optimise — or migrate from Expo managed workflow to bare React Native when the project needs full native access.
UI/UX Design for React Native
Component-level Figma design systems mapped directly to React Native's styling model — platform-specific variants for iOS and Android, dark mode, accessibility compliance, and 60fps animation specs included.
AI-POWEREDLearn how we work
Delivered faster with AI tooling
We don't just write code; we orchestrate intelligence. By integrating Copilot-assisted generation and AI-driven automated testing, we reduce time-to-market by up to 40%.
Copilot-Assisted Generation
LLM-backed development to eliminate boilerplate delays.
AI Predictive Testing
Anticipating edge cases before they enter production.

Our Development Journey
A streamlined, transparent path from vision to launch.
01
Discovery & Architecture
1–2 weeks
We define your navigation structure, state management approach, native module requirements, and shared-code strategy with your web team if applicable — producing a technical spec signed off before design starts.
02
UI/UX Design
2–3 weeks
High-fidelity Figma designs with platform-specific variants for iOS and Android. Components are named and structured to map directly to the React Native component library we build — no interpretation gap between design and code.
03
Development
4–14 weeks
Two-week sprints with a working build distributed via Expo EAS or TestFlight and Play Internal Testing from sprint two. You test on your real device throughout — not a simulator recording.
04
QA & Device Testing
1–2 weeks
Automated end-to-end tests with Detox, unit tests with Jest, manual testing across iOS and Android covering different OS versions and screen sizes, and a performance audit using React Native's built-in profiler.
05
Store Submission
3–7 days
We handle App Store and Google Play submissions in parallel — privacy manifests, App Privacy labels, store metadata, screenshots, App Preview videos, content rating, and all review feedback until both apps are live.
06
Post-Launch & Iteration
Ongoing
Crash monitoring via Sentry, JS bundle OTA updates via EAS Update for fast patches without store resubmission, OS compatibility maintenance, and feature iteration. CI/CD with Fastlane handles full releases.

Frequently Asked Questions
React Native vs Flutter — which should I choose?+
React Native is the better fit if your team already knows React or JavaScript, or if you want to share code and engineers between your web and mobile products. Flutter is the better fit if you prioritise pixel-perfect rendering consistency across platforms and do not have an existing React codebase. We advise on the right choice after understanding your team and product context.
Is React Native really native, or is it a web view?+
React Native renders using actual native UI components — UIKit on iOS and Android Views on Android — not a web view wrapped in a shell. The JavaScript layer drives the logic; the platform's own rendering engine draws the UI. The result is genuine native performance and feel, not an approximation.
Can React Native access native device features like camera, NFC, or Bluetooth?+
Yes. React Native has built-in APIs for common features. For more specialised hardware — NFC, Bluetooth LE, proprietary device SDKs, or custom sensors — we write native modules in Swift and Kotlin that bridge directly into the JavaScript layer.
How long does React Native development take?+
An MVP is typically 8–12 weeks to both stores. A full product with complex integrations and custom native modules runs 14–20 weeks. You get a milestone-based timeline with fixed delivery dates after the scoping session.
What does React Native app development cost?+
MVPs start from $11,000. Full product builds from $26,000. Pricing is based on feature scope, number of native modules required, and backend complexity. Fixed-scope quote before signing.
Can you update the app without going through the App Store review?+
Yes — for JavaScript and asset changes, we use Expo EAS Update (OTA updates) to push fixes and improvements directly to users' installed apps without a store resubmission. Binary-level changes (new native modules, SDK upgrades) still require a full store release.
Who owns the source code?+
You own everything — React Native TypeScript source, native module Swift and Kotlin code, Figma designs, CI/CD configuration, and documentation. Full IP transfer at project close, no retained rights.
Do you provide post-launch support?+
Yes. We offer maintenance retainers covering crash monitoring, React Native version compatibility, OTA patch management, and feature iteration. Critical issues are responded to within 24 hours for active retainer clients.
