Offshore Cross-Platform App Development: One Codebase, Both App Stores
Our offshore cross-platform app development service builds a single Flutter or React Native codebase that ships to both the App Store and Google Play, delivered by a dedicated team in India. Compared with two native teams, cross-platform development typically cuts build cost by 30–40% and reaches both stores weeks sooner. A seven-person cross-platform team costs about USD 25,500 a month. This page explains when cross-platform is the right call, when native still wins, and how to choose a framework. Share your app idea and we’ll recommend a platform.
Cross-Platform vs Native: An 8-Criteria Decision Table
Cross-platform is the right default for most new apps, but not for all of them. The decision depends on how much your app relies on device hardware, how demanding its interface is and how long you will maintain it. The table compares cross-platform and native development across the eight criteria that decide most projects. Score your app against each row. If native wins on three or more rows that matter to you, build native. Every team we staff for this work is part of our offshore development center in india.
| Criterion | Cross-platform (Flutter, React Native) | Native (Swift, Kotlin) |
|---|---|---|
| Performance ceiling | Near-native for most business and consumer apps | Highest; needed for games, heavy graphics and real-time media |
| Native API access | Most APIs via plugins; new or niche APIs need native code | Immediate access to every platform API |
| Team cost | One codebase, typically 30–40% lower build cost | Two codebases and two specialist teams |
| Time to both stores | Both stores from one release cycle | Two parallel builds that are harder to keep in sync |
| Long-term maintenance | One codebase to update, plus framework upgrades | Two codebases, each with its own upgrades |
| Hiring pool | Large pool of Flutter and React Native engineers in India | Deep Swift and Kotlin pools, staffed separately |
| OS-update lag | New OS features may wait for framework or plugin support | Available on release day |
| Offline capability | Strong, with local databases and sync libraries | Strong, with full control of background behaviour |
Performance Ceiling
Modern cross-platform frameworks run smoothly for forms, lists, dashboards, commerce and content. Native still wins for 3D games, augmented reality, heavy video processing and interfaces that push every frame to the limit.
Native API Access
Plugins cover cameras, payments, maps, push notifications and biometrics. Newer or niche APIs, such as the latest wearable or AR features, still need native code connected through a platform channel or native module.
Cost and Time to Market
One codebase means one team, one backlog and one release cycle for both stores. For a typical business app, that saves 30–40% of build cost and several weeks of calendar time.
Maintenance and OS Updates
A cross-platform app has a single codebase to maintain, but it depends on the framework keeping pace with Apple and Google. Plan for framework upgrades as well as the annual iOS and Android updates.
Making the Call
Score your app on the eight criteria with your team. If you are still unsure, a short discovery sprint can test the riskiest features in both approaches before you commit budget.
Choosing a Cross-Platform Framework: Flutter or React Native
Once you’ve decided on cross-platform, the next choice is the framework. Flutter and React Native both power production apps for major brands, and India has deep talent pools for both. The right choice depends less on benchmarks than on your existing team, your design ambitions and what else you plan to build. The factors below decide most framework choices in practice. Each framework also has its own detailed guidance page.
Your Existing Team’s Skills
If your web team already works in React and TypeScript, React Native lets them review and contribute to mobile code. If you have no existing JavaScript investment, that advantage disappears.
Design Ambition
Flutter draws every pixel itself, so highly custom, brand-led interfaces look identical on both platforms. React Native uses each platform’s native components, so apps feel closer to iOS and Android defaults.
Web and Desktop Plans
Flutter can target web and desktop from the same codebase, which helps internal tools and admin apps. React Native pairs well with an existing React web app through shared business logic instead.
Native Integration Depth
Both frameworks handle native modules well. Apps that rely on heavy native SDKs, such as payments, health or IoT, should prototype the hardest integration in the chosen framework before committing to it.
Long-Term Hiring
India has strong offshore hiring pools for both frameworks. Check that your vendor has senior engineers in the framework you choose, not generalists who switch between the two from project to project.
Offshore Cross-Platform Team Composition and Cost
A cross-platform team needs fewer mobile engineers than two native teams would, but it still needs native skills on call. The configuration below is the most common starting point for a new app, delivered as a managed dedicated team in India. Rates are all-in, covering salary, benefits, equipment, management and margin, and match our published pricing packages. Scale the team up once the first release is live and the roadmap is clear.
| Role | Count | Monthly rate per role (USD) |
|---|---|---|
| Product manager or business analyst | 1 | 4,000 |
| UI/UX designer | 1 | 3,500 |
| Flutter or React Native engineer | 3 | 3,800 |
| Backend engineer | 1 | 3,800 |
| Mobile QA engineer | 1 | 2,800 |
| Team total | 7 | ~25,500 per month |
Cross-Platform Engineers
Three engineers give enough capacity for steady feature work and code review. At least one of them should be senior enough to write Swift and Kotlin when a plugin falls short.
Design for Two Platforms
The designer decides where the app should look identical on both platforms and where it should follow iOS or Android conventions, such as navigation and back gestures. A design sprint settles this early.
Backend and APIs
A dedicated backend engineer builds the APIs, authentication, push notifications and admin tools the app needs. That keeps the cross-platform engineers focused entirely on the app itself. It also covers analytics and integrations.
QA on Both Platforms
One codebase does not mean one test pass. QA tests every release on real iPhones and Android devices, because rendering, permissions and keyboards behave differently on each platform. Automated tests cover both.
Estimating Your App
Use our project cost calculator to model your team and timeline. Then request an itemised proposal that shows each role, rate and milestone before you commit. Estimates are itemised by phase.
How Offshore Cross-Platform Development Is Delivered
Delivery follows the same phased model as any mobile project, plus a few steps specific to a shared codebase. The phases below cover how a cross-platform app moves from idea to both stores, and what happens after launch. Each phase ends with an artefact you approve before the next one starts. The team works a shifted day with two to three hours of overlap with US Eastern mornings, so decisions happen in real time.
Discovery and Framework Proof
Two to four weeks of discovery confirm the scope and test the riskiest native integration in the chosen framework. This is the cheapest point at which to discover a plugin gap.
Shared Design System
The designer builds one component library, with platform-specific variants where needed. Engineers implement it once, so screens stay consistent across both apps as new features are added. It also speeds up design reviews.
Sprint Build
Two-week sprints deliver builds to TestFlight and Google Play internal testing at the same time. You test both platforms from every sprint, rather than one platform first and the other later.
Simultaneous Store Release
Both apps are submitted from your own developer accounts in the same release window. Platform-specific privacy disclosures are prepared separately for each store. Phased rollout runs on both stores together, with crash monitoring from the first hour.
Upgrades and Maintenance
After launch, the team schedules framework upgrades alongside the annual iOS and Android updates. Continuity is backed by our delivery guarantees, including replacement terms. Upgrades are planned and scheduled, never rushed.
When Cross-Platform Is the Wrong Choice
Cross-platform is not a universal answer, and choosing it for the wrong app creates costs that only surface after launch. Being clear about where native wins also makes our recommendation credible where cross-platform is right. In the cases below, we advise native development instead, or a hybrid in which most of the app is cross-platform and a few screens are fully native. Our mobile app development services cover native builds for these cases.
Graphics-Intensive Apps
3D games, augmented reality and apps with complex real-time animation need direct access to Metal, Vulkan or a game engine. Cross-platform frameworks add overhead in exactly the places these apps cannot afford it.
Deep Hardware Integration
In apps built around Bluetooth peripherals, medical devices or custom sensors, most of the code lives in native layers. A cross-platform shell adds complexity without saving much effort. Native is usually simpler here.
Day-One OS Features
If your product strategy depends on adopting new Apple or Google features the day they launch, native development avoids waiting for framework and plugin support to catch up. That lag is usually weeks.
One-Platform Products
If your users are overwhelmingly on one platform, a native app for that platform is simpler and often cheaper than a shared codebase you would only half use. Expand later if demand appears.
The Hybrid Option
Many apps work best as mostly cross-platform, with a few performance-critical screens written natively. Both Flutter and React Native support embedding native screens cleanly within the shared app. It balances cost and performance.
Frequently Asked Questions
Offshore cross-platform app development means building one app codebase, usually in Flutter or React Native, that runs on both iOS and Android. A dedicated team in another country, such as India, does the work under your direction and publishes both apps from your own Apple and Google developer accounts.
