Why MagmaLabs for React Native
A mobile app is only as good as the backend, releases and support behind it. We build all of it, so the app keeps working after launch.
02
Release pipeline included
EAS builds, store submissions, staged rollouts and over-the-air fixes, so shipping a release is routine, not an event.
03
Full stack, one team
The same engineers write the APIs, auth, push notifications and admin tools, in Node or Rails, so the app never waits on another vendor.
04
TypeScript and tests
Strict TypeScript, Jest and Maestro end-to-end tests in CI from week one. Refactors stay safe as the app grows.
Our React Native services
New apps, inherited apps and the work that keeps a live app current on both stores.

FAQ
Something else? Email hello@magmalabs.io.
Is React Native a good choice for my app?
For most products, yes. One TypeScript codebase ships to iOS and Android with native performance for typical app workloads, and it shares logic and talent with your React web app. We recommend fully native only when the app depends on heavy custom graphics, low-level hardware or platform features React Native cannot reach yet.
Do you use Expo or bare React Native?
We default to Expo with development builds and EAS. It speeds up builds, store submissions and over-the-air updates without limiting native code. For apps with existing native modules we work in bare React Native or adopt Expo modules incrementally.
Can you take over or rescue an existing React Native app?
Yes. We start with an audit of the codebase, dependencies, crash reports and release pipeline, then fix the most urgent issues first. Many apps we inherit are several versions behind and need an upgrade before new features.
Can you migrate our native iOS and Android apps to React Native?
Yes, screen by screen. React Native can live inside an existing Swift or Kotlin app, so you migrate incrementally instead of freezing development for a rewrite.
Do you handle App Store and Google Play releases?
Yes. Signing, store listings, review guidelines, staged rollouts and over-the-air updates through EAS Update. We set up the pipeline so every release is repeatable, not a one-person ritual.
Who builds the backend?
We do, if you need it. The same team writes the APIs, auth, push notifications and admin tools in Node or Rails, so the app never waits on another vendor.
How much does React Native development cost?
React Native engineers through Team Embed start at $8,500 per engineer per month. MVPs, typically 6 to 10 weeks, and full apps, typically 3 to 6 months, are quoted as a fixed price after scoping. If your app was built fast or with AI tools, the Production Readiness Audit is a fixed $4,900.
Can our web team share code with the mobile app?
Often, yes. With TypeScript, a monorepo and shared packages for types, validation and API clients, web and mobile stay in sync. UI is usually platform specific, and we are honest about where sharing helps and where it does not.
