Why React Native Projects Fail Before They Launch

The wrong development partner turns a straightforward cross-platform build into a platform-specific debugging nightmare. Here's what we see founders deal with before they find us.

Two Codebases Doubling Your Engineering Cost

Separate iOS and Android codebases mean two teams, two roadmaps, double the budget — before you ship a single feature to either platform.

Junior Developers on a Senior Architecture Problem

Agencies pitch React Native but staff the project with developers who learned the framework last month. You pay for their on-the-job training.

Performance Issues That Only Appear in Production

Jank, slow renders, and memory leaks that pass every demo and break under real user load. Problems that only surface when your actual users find them first.

Vendor Lock-In Through Undocumented Architecture

Proprietary component libraries, no documentation, and teams that vanish after App Store submission. You own the app but can't extend it without going back to the vendor.

Why Product Teams Choose Devlyn for React Native Development

We're not another offshore mobile shop. Devlyn is an AI-driven, product-led engineering partner that takes ownership of your mobile delivery outcomes.

AI-First Development Workflow

AI reviews PRs, detects component drift, and benchmarks performance - 40% fewer post-launch crashes and regressions on every build we ship.

Senior-Only React Native Engineers

Every developer has 5+ years of React Native production experience - no juniors learning cross-platform patterns on your live app.

48-Hour Onboarding

Submit your requirements and your dedicated mobile team starts within 48 hours - working builds on real devices in your hands by week one.

Full Transparency

Daily standups, shared Slack and GitHub access from day one. Every component, every build, every architecture decision visible and documented.

India Advantage

Senior React Native engineers at 40–60% lower cost than equivalent US or UK mobile teams - same output, fraction of the overhead.

Flexible Models - Pick What Fits

Every model includes full IP ownership, NDA protection, and dedicated project management. Scale up or down - no long-term lock-in.

End-to-End React Native App Development Services

From greenfield mobile MVP to legacy native migration, we build every layer of your cross-platform app so you ship to both stores without running two engineering teams.

Cross-Platform App Development

One codebase, two stores. iOS and Android from a single React Native project - built for performance, not just compatibility.

React Native MVP Development

Validate your mobile idea in 6 weeks without maintaining separate native codebases. Production-quality, App Store-ready from day one.

App Performance Optimisation

Diagnose and fix jank, slow TTI, memory leaks, and re-render cycles. Real-device profiling, not emulator benchmarks.

Native App Migration to React Native

Migrate your existing native iOS or Android app to React Native - preserving functionality, improving maintainability, reducing long-term cost.

Third-Party API and SDK Integration

Payments, maps, push notifications, biometrics, analytics, and CRM integrations - clean abstraction layers your team can maintain.

App Store and Google Play Submission

App Store and Google Play submission, compliance review, screenshot optimisation, and review management. We handle the friction of going live.

React Native UI Implementation

Pixel-perfect Figma-to-native components with platform-specific UI conventions respected on both iOS and Android - not web CSS ported over.

Post-Launch Maintenance and Support

OS version compatibility, crash monitoring, dependency updates, and feature enhancements. We stay embedded as your mobile product evolves.

The Right Stack for Your Mobile Architecture

We're not a one-framework shop. Every project uses the stack that best serves its performance, integration, and platform requirements.

Full-Cycle React Native Development Process

Transparency kills risk. Here's exactly what happens from the moment you reach out to the day your app goes live - and beyond.

1

Discovery and Mobile Requirements

We start with your mobile use cases not a feature list. User journeys, platform requirements, offline needs, and measurable performance benchmarks defined before architecture begins.

2

Architecture and Component Design

AI-assisted architecture reviews for performance, scalability, and cost. You sign off on the component architecture and navigation structure before we write a single line of code.

3

Agile Development Sprints

Two-week sprints with working builds on real devices. You test a functional app every 14 days not a prototype running in a browser simulator.

4

Continuous QA and Device Testing

Automated testing on every commit. AI-powered code reviews catch performance regressions and platform-specific issues before human reviewers see the build.

5

App Store Deployment and Launch

CI/CD pipelines via Fastlane and EAS Build, TestFlight and internal track distribution, App Store and Google Play submission with OTA update capability from day one.

6

Post-Launch Growth Support

Crash monitoring, OS version compatibility, dependency updates, and feature enhancements. We stay engaged as your mobile user base and product roadmap grow.

Is Devlyn Right for Your Mobile Project?

Real sprints not waterfall disguised as Agile. Working builds on real devices every two weeks with full performance and burndown visibility.

1.

Founders Launching a Mobile MVP

You need a production-quality iOS and Android app without hiring two separate native teams. We build cross-platform from a single React Native codebase. App Store-ready in 6 weeks, architecture that holds when you scale.

2.

Startups Replacing Native iOS and Android Teams

Two native codebases are doubling your roadmap time and your engineering cost. We migrate to React Native domain by domain no big bang rewrite, no features lost, one team maintaining both platforms going forward.

3.

Product Companies Adding Mobile to Their Web App

Your web product is winning deals that need a mobile companion. We build the React Native app against your existing API clean, consistent, and on-brand across iOS and Android without rebuilding your backend.

4.

CTOs Rescuing a Failing React Native Project

Jank, crashes, an undocumented component library, and a vendor who's stopped responding. We audit the codebase, triage the critical issues, and take over delivery same week if needed.

Frequently Asked Questions

It depends on scope, complexity, and integration requirements. A React Native MVP typically starts at $14,400 for a 6-week engagement. Mid-complexity apps with third-party integrations, custom UI, and backend development run $25,000–$60,000. Full-featured consumer or enterprise apps can exceed $100,000. Every project starts with a free scoping session and a transparent estimate no hidden fees.

A focused MVP runs 6–8 weeks. A mid-complexity app with custom integrations and multi-screen architecture runs 10–16 weeks. We scope every project specifically timelines are anchored to your actual feature set and integration requirements, not boilerplate estimates from a project calculator.

React Native is the right default for most product startups and SaaS companies adding mobile. One codebase, one team, 80–90% of native performance for most use cases. Native is better when you need bleeding-edge hardware access, game-level graphics, or extremely complex platform-specific UI. We'll tell you which fits your specific product not the one that's easier for us to build.

Performance is a first-class deliverable not a post-launch concern. We profile on real iOS and Android devices from sprint one, not emulators. Every PR is reviewed for re-render cycles, unnecessary state updates, and heavy JavaScript thread usage. We use Reanimated 3 for animations, memoisation patterns throughout, and Hermes engine by default for faster startup and reduced memory footprint.

We manage the full submission process developer account setup, compliance review, screenshot and metadata optimisation, binary preparation, and review management. We've navigated App Store review rejections across every major category. You hand us the app, we handle the friction of getting it live on both stores.

Yes - and that's the most common engagement. We build the React Native app against your existing REST or GraphQL API. We document the integration points, handle authentication flows, manage offline state, and build the abstraction layer that keeps your mobile codebase decoupled from backend changes. No backend rewrite required.

Standard MSA assigns all IP to you. Mutual NDA signed before access provisioning. Engineers operate fully within your GitHub org - source code never leaves your perimeter. App Store credentials and signing certificates stay in your developer accounts throughout the engagement.

We start with a codebase audit - performance profiling, dependency review, architecture assessment, and crash log analysis. From there we recommend the smallest intervention that solves the real problems. Some apps need refactoring. Some need a navigation overhaul. Some need a new developer, not a new architecture. We'll tell you which - not upsell a rebuild when a targeted fix is the honest answer.
