Outsourced React Native development for MVPs and growing apps
For founders who need an iOS and Android app in front of real users this quarter, and product companies whose app has outgrown the people who started it. We build and run React Native apps as an outsourced team: a fixed-scope project when the scope is clear, a dedicated squad when the roadmap keeps moving.
React Native is also the mobile stack behind our MVP development offer. One TypeScript codebase ships to both stores and shares types with your backend, and we drop into Swift or Kotlin when a feature needs it.
Since 2014 we have run more than 250 engagements, coordinated from Miami by founder and CEO Javier Uanini, with senior engineers across Latin America working in US time zones.
What outsourced React Native development covers
React Native lets one team write an iOS app and an Android app in TypeScript and React, rendering real native views, not a web page in a wrapper. Since version 0.76 the New Architecture (the Fabric renderer and TurboModules) is the default, removing most of the old bridge overhead.
Outsourcing it means one team owns the whole product, not only the screens: the API, the admin panel, push, payments, analytics and the release process for both stores. If you already have a mobile lead and only need extra hands in your sprints, hire React Native developers through staff augmentation instead.
- Two native apps in Swift and Kotlin fit products built on OS-level features such as background processing, camera pipelines or watch surfaces, at the cost of two codebases. Our iOS app development team takes those projects.
- Flutter offers similar reach but draws its own widgets and uses Dart. For teams without React experience that want identical UI everywhere, compare our Flutter development services.
- React Native fits best when you already run React or Node.js, want shared types between app and API, and need both stores on one schedule.
What we build with React Native
MVP apps with payments
Sign-up, the core flow, payments and push for a first release. Digital subscriptions use store in-app purchases; real-world services use a provider such as Stripe or Mercado Pago.
Expo apps and build pipelines
We start most new apps on Expo: cloud builds, store submission from CI, and over-the-air updates for JavaScript fixes. We go bare only when a native dependency forces it.
Native modules in Swift and Kotlin
Bluetooth devices, background location, HealthKit, custom camera work. Each module gets a typed interface, an owner and tests.
The API and admin around the app
We usually pair React Native with a Next.js or Node.js backend, a web admin and an OpenAPI contract, so the app's API client is generated, not handwritten.
Store release and compliance
App Store Connect and Play Console setup, privacy labels, data safety forms, staged rollouts, crash reporting and rejection responses.
Rescues and upgrades
Apps stuck on an old version, with failing builds or a team that left. We audit first, then upgrade on a branch while releases continue.
Who hires us for React Native work
About 40% of our clients are venture-backed startups.
Founders building a first app
You have a validated idea and a clear user journey but no engineering team. You need both stores, payments, and a codebase a future CTO will keep.
Web companies adding mobile
Your product runs on React or Next.js and customers want an app. We reuse your types and API and add the mobile release discipline your web team never needed.
Product teams scaling an app
The app has traction and a backlog two developers cannot clear. A dedicated squad takes a product area end to end while your team keeps the rest.
Owners of an inherited codebase
An agency or freelancer built the app and moved on. Builds fail, dependencies are years old, and you need an audit before new features.
One codebase, two stores, and an installable build every two weeks.
How a React Native engagement runs
Discovery, 3 to 5 days
We map the core user journey and its native needs, then decide Expo or bare, which payments go through the stores, and what the first release leaves out. You get a written scope and estimate either way.
Team assembly, 5 to 10 days
You meet the engineers before they start. A typical MVP team is a React Native lead, a backend engineer, and part-time QA and design.
Setup and first build
Repository, CI with type checks, tests and secret scanning, and preview builds on TestFlight and Play internal testing. Store accounts are opened now, because verification can take weeks.
Two-week sprints
Each sprint ends with a demo on real devices and a retrospective. The first build you can install lands in week 3 or 4, and scope changes go through a written change request.
Release and after
We plan store review into the schedule and check your payment and account flows against the App Store Review Guidelines early. After launch you keep the team, scale down with 30 days' notice, or take the code in-house with documentation.
Proof: a React Native rental app built in 12 weeks
Our clearest published example is an owner-first rental-management app for an Argentine real estate company (name withheld): a fixed-scope, 12-week contract started in October 2026, with launch planned for early 2027. It is still in delivery, so we describe what exists, not results.
What the app does
Owners manage properties, tenants and leases. Rent updates from the official ICL and CPI indices, charges go out as Mercado Pago payment links, and receipts are PDFs. Tenants install nothing: they get email and WhatsApp notices and pay through a link. Owner subscriptions use in-app purchases.
Stack: Expo and React Native, a versioned Next.js 16 API on Vercel, PostgreSQL on Neon, Prisma 7.
How it is delivered
An OpenAPI contract generates the app's API client, and CI blocks breaking changes to it. Maestro flows test the main journeys on a simulator, including one that checks an owner can never see another owner's data. One senior engineer works with AI coding agents under written repository rules, and every change is reviewed before it merges.
By early November the first iOS preview build was out for review.
Engagement models and pricing
Project-based
Fixed scope and price after discovery. Typical builds run USD 15k to 120k with 2 to 6 engineers over 1 to 6 months. Best for an MVP or a clearly defined release.
Dedicated team
A squad of 4 to 12 people that owns a product area or the whole app, at USD 12k to 60k per month, usually for 6 to 24 months or longer. Best once the app has users and priorities shift every sprint.
Staff augmentation
One to five React Native engineers inside your own team at USD 4k to 9k per month each, for 1 to 12 months. Best when you already have a mobile lead and a release process.
Our advice: founders without a team should start project-based, because a fixed scope forces the hard calls on what to leave out. Once the app has paying users, the same engineers can move to a dedicated team. Every assignment carries a 2-week satisfaction guarantee.
Outsourced team, freelancer, in-house or agency
| Option | Fits when | Watch for |
|---|---|---|
| Outsourced React Native team | One accountable team should own both stores, the API and releases, starting within weeks. | You still need a product owner who makes weekly scope calls. |
| Freelance developer | The task is bounded: one screen, one native module, a version bump. | No backup, and signing keys often live on their laptop. |
| In-house hiring | Mobile is your core product for years and you can wait for recruiting. | Senior mobile engineers take months to hire, and the first one must also build the release process. |
| Generalist agency | A campaign app with a fixed launch date and little work after launch. | Ask who builds the app and who maintains it after launch. |
Your code, your store accounts, your signing keys. From the first commit.
Risks we plan for in React Native projects
Store accounts and signing
Apple and Google accounts are registered to your company and we join as team members. Signing credentials live in accounts you control.
IP and code custody
Your GitHub or GitLab organization holds the repository from day one, and NDAs and IP assignment are signed before discovery.
Native dependency debt
Every third-party native library is checked for New Architecture support and maintenance before we add it.
Over-the-air updates
OTA updates carry JavaScript fixes only, within store rules. Native changes always ship as a store build.
Time zones
Our engineers across Latin America work in US hours, so demos and release calls happen in your day. See our nearshore software development model.
AI-assisted code
AI coding agents never merge their own work: a senior engineer reviews every pull request, and CI scans for secrets and vulnerable dependencies. Our AI development team applies the same rules to AI features.
Frequently Asked Questions
Start on Expo unless you know you need something it cannot do. Its cloud builds, store submission and over-the-air updates save weeks on an MVP, and config plugins cover most native libraries. We go bare when a native SDK has no plugin or an enterprise device-management build requires it. Moving later is a planned step, not a rewrite.
You do. The repository sits in your organization, the Apple and Google developer accounts are registered to your company, and signing credentials live in accounts you control. NDAs and IP assignment are signed before work starts.
Yes. Discovery becomes an audit of build health, dependency versions, New Architecture readiness, crash reports and test coverage. You get a written plan that separates must-fix items from upgrades that can wait, and releases continue while the upgrade runs on a branch.
Project-based builds run 1 to 6 months; a focused MVP sits at the short end, like the 12-week rental-management app in our case studies. Store review comes on top, and new organization accounts can take weeks, so we open them in week one.
Both. After discovery we can fix scope and price for a defined release; project-based work typically runs USD 15k to 120k. If the roadmap is still moving, a dedicated team of 4 to 12 people bills monthly at USD 12k to 60k, and you can scale down with 30 days' notice.
When the product is mostly OS-level features, such as background audio, advanced camera pipelines or watch apps, two native apps are usually cheaper over time. When your team has no React experience and wants identical custom UI everywhere, Flutter is a fair alternative. If React Native is the wrong call, we say so in discovery.
