iOS and Android Apps From One React Native Codebase
Cross-platform mobile development that ships to both stores faster and cheaper than building native twice. Production-grade React Native, with native modules where it counts.

Everything you need to ship to both stores
One accountable team handling design, engineering, native integrations, submissions, and post-launch support.
One Codebase, Both Platforms
React Native for iOS and Android from a single codebase. Ship to both stores at once. Half the maintenance, half the cost, none of the platform-fork pain.
Native Where It Matters
Native modules for camera, biometrics, push, deep links, background tasks. Everything that needs platform APIs, written platform-native, wrapped in clean JS interfaces.
App Store Submissions
We handle TestFlight, App Store Connect, and Google Play submissions. Including the review-rejection appeals nobody warns you about.
Push Notifications & Deep Linking
Firebase Cloud Messaging, OneSignal, or custom. Universal links that route to the right screen, even on cold starts. Real engagement infrastructure.
Offline-First Architecture
Apps that work without signal. Local-first data, optimistic updates, conflict resolution, background sync. The way good mobile apps actually feel.
Crash Reporting & Analytics
Sentry, Crashlytics, Mixpanel. You see issues before users complain, and you measure the metrics that move the business.
A transparent path from first call to App Store
Four phases. Fixed scope before code. TestFlight builds every two weeks.
- 01 1–2 weeks
Discovery
We map the user flows, platform requirements, native integrations, and App Store strategy. Outcome: a fixed-cost statement of work and submission timeline.
- 02 Signed before kickoff
Statement of Work
Milestones, deliverables, platform decisions (managed Expo vs bare React Native), and submission plan. Agreed up front, no surprises.
- 03 2-week sprints
Build
TestFlight and internal Android builds at the end of every sprint. Real devices in your hands as the app evolves. Demos, feedback, fast iteration.
- 04 Week 10–18
Launch & Store Approval
TestFlight beta, App Store and Google Play submissions, review-pass coordination, marketing assets. We don't disappear until your app is in the stores.
The kinds of teams we ship mobile apps for
React Native is the right call when you want both platforms, fast, with a team that's done it before.
Startups launching mobile-first
Your product needs to live in users' pockets. We get you to TestFlight in weeks, then to both App Stores without doubling your engineering bill.
Web apps adding a mobile layer
You have a working web product and customers asking for an app. We build a React Native client that shares your existing API and design system.
Companies replacing native legacy apps
Two old codebases (Swift + Kotlin), two siloed teams, half the velocity. We migrate to React Native incrementally so nothing breaks for your users.
B2B apps with field operations
Inspections, sales kits, dispatch, telehealth, logistics. Apps that work offline, sync reliably, and stay fast on cheap Android hardware.
A modern, boring, battle-tested mobile stack
The same tools Meta uses to ship Facebook and Instagram. Battle-tested at scale.
React Native
One JavaScript codebase, two production apps. The framework Meta uses on Facebook, Instagram, and Marketplace.
TypeScript
Strict typing across the app. Catches platform-specific bugs before they hit the store.
Expo (when it fits)
Managed builds, over-the-air updates, EAS submission. For projects without heavy native customization, it cuts weeks off the timeline.
Reanimated + Gesture Handler
60fps animations and native-feeling gestures. The difference between an app that feels cheap and one that feels premium.
React Query / Zustand
Server state and client state managed cleanly. Optimistic updates, cache invalidation, offline support, all without redux boilerplate.
Sentry + Firebase
Crash reporting, performance monitoring, analytics, push, remote config. The mobile ops stack we install on day one.

What teams ask us about mobile
Short, honest answers. If yours isn't here, book a call and we'll answer it directly.
How long does it take to build a mobile app?
// Answer
Most React Native apps ship to TestFlight in 8 to 12 weeks, and to both App Stores in 10 to 18 weeks. The exact timeline depends on native integrations, offline requirements, and how fast Apple's review queue moves. We lock the timeline in discovery, before any code is written.
What does a mobile app cost?
// Answer
Mobile apps are fixed-scope, so you get a defined total upfront: both iOS and Android from one React Native codebase. Heavy native customization or platform-specific UI adds to that. Book a 30-minute call and we'll give you a concrete range based on your scope.
Why React Native instead of Swift and Kotlin?
// Answer
Half the cost, half the maintenance, and 95% of the user experience. React Native is what Meta, Microsoft, Shopify, and Discord use in production. For projects with heavy AR/VR or graphics-intensive 3D, we recommend native. For everything else, React Native wins.
Will my React Native app feel native?
// Answer
Yes, if it's built right. We use platform-specific UI components (iOS-style on iPhone, Material on Android), native animations via Reanimated, and gesture handlers that mirror the platform. Most users can't tell our apps from native ones.
Can you handle App Store submission and rejections?
// Answer
Yes. We handle TestFlight, App Store Connect, and Google Play submissions, including the appeals process for the occasional review rejection. We've shipped to both stores dozens of times since 2017.
What happens after launch?
// Answer
Mobile apps need more post-launch care than web apps: OS updates, store policy changes, crash fixes from edge-case devices. We offer ongoing maintenance retainers that handle all of this so your team doesn't have to.
Three ways to work together
Fixed-scope project, ongoing mobile team, or senior engineers inside your own team. Pick the model that fits your stage.
Fixed-Scope Project
Best for clear scope and a fixed budget.
- Defined scope and milestones
- Fixed timeline and budget
- Signed SOW before kickoff
- App Store and Google Play submission
- 30 days of post-launch support
Dedicated Team
Best for products that need an ongoing partner.
- A senior team that's truly yours
- Sprints, roadmaps, and demos
- Full visibility and reporting
- Flexible scope as you grow
- Mobile, web, DevOps, and support
Staff Augmentation
Best for adding senior engineers to your team.
- Senior React Native engineers
- Embedded in your workflow
- Scale up or down on a sprint's notice
- Your process, your tools
- No long-term lock-in
What else we do
One team, one contract, full product journey.
