Why choose SageGridLab for your React Native project
We don't just build apps — we build mobile experiences that users love. Every project starts with user research, platform guidelines, and a clear understanding of your business goals. Then we craft something that stands out in the App Store and Google Play.
Cross‑Platform Efficiency
One codebase, two stores. We deliver iOS and Android simultaneously — cutting development time and maintenance costs in half without sacrificing native look and feel.
Mobile‑First Mindset
We think in gestures, touch targets, performance budgets, and offline support. Every decision is made with the mobile user in mind — from navigation to animations.
App Store Ready
We don't just build apps — we package them for success. From App Store / Google Play optimization to submission guidelines, we handle every step of the release process.
What we do
Our React Native Capabilities
From MVP to enterprise‑grade apps — our React Native expertise covers the full mobile development lifecycle.
React Native App Development
Full‑cycle development of cross‑platform apps with native performance. We handle everything from navigation and state management to push notifications and deep linking.
MVP Development
Launch your product faster with a well‑scoped MVP. We prioritize core features, validate your idea in the market, and iterate based on real user feedback.
Native Module Integration
Need camera access, biometrics, or ARKit? We write native modules when React Native doesn't cut it — bridging the gap between JavaScript and native capabilities.
Mobile E‑Commerce
Native‑feeling shopping experiences with seamless checkout, Apple Pay / Google Pay integration, and real‑time inventory sync. Built to convert on mobile.
App Maintenance & Support
We keep your app healthy — OS upgrades, dependency updates, crash monitoring, and feature enhancements. Retainer or per‑project, we've got your back.
App Reengineering & Migration
Migrating from native iOS/Android or hybrid? We modernize your codebase, improve performance, and unlock the speed of React Native development.

React Native development process
A transparent, repeatable process refined across 80+ mobile projects. You always know what's happening and why.
Discovery & Scoping
User interviews, competitor analysis, and platform requirements. We define your MVP, architecture, and timeline before we write a single line of code.
UX & UI Design
User flows, wireframes, and pixel‑perfect designs for iOS and Android — including gestures, navigation, and platform‑specific patterns.
React Native Development
Agile sprints with bi‑weekly demos. We build your app with clean architecture, reusable components, and a staging environment available from day one.
QA & Testing
Device‑specific testing, performance profiling, crash analytics, and App Store / Google Play compliance checks. Zero critical bugs to production.
App Store Submission
We handle the entire submission process — App Store & Google Play metadata, screenshots, app review, and launch. You get your app in users' hands, worry‑free.
Ongoing Support
Flexible retainer agreements for maintenance, feature updates, OS upgrades, and monitoring. We become your long‑term mobile engineering partner.
Our stack
React Native technologies we use
We pair React Native with the best ecosystem tools — from state management to native APIs.
React Native app costs depend on complexity and feature set. An MVP typically ranges from $30,000–$60,000. A full‑featured consumer app can range from $60,000–$180,000+. We provide a transparent fixed‑price estimate after a free 1‑hour discovery call.
Absolutely — that's the power of React Native. We deliver a single codebase that runs on both iOS and Android, with platform‑specific customizations where needed (navigation, gestures, permissions). This approach saves 40–60% compared to building two separate native apps.
React Native has a robust ecosystem of community libraries for most native features. When we need custom functionality, we write native modules (Swift / Kotlin) to bridge the gap. Your app will feel and perform just like a native app — because we don't compromise on native capabilities.
An MVP typically takes 10–16 weeks. A full‑featured app takes 16–30 weeks depending on scope. We work in agile sprints and deliver a beta version (TestFlight / Google Play Beta) within the first 6–8 weeks, so you can start testing and gathering feedback early.
Yes — we manage the entire submission process, including preparing metadata, screenshots, app previews, and responding to reviewer feedback. We have a 99% first‑time approval rate across all our projects.
Fill out our contact form with a brief description of your app idea. We'll respond within one business day to schedule a free 1‑hour discovery call. After the call, we'll provide a detailed scope and budget estimate within 48 hours — no strings attached.
