Key Takeaways
Instagram, Shopify, Coinbase, and Tesla all shipped production apps on React Native at scale and kept using it. But fintech has several nuances that mean it might not necessarily be the right option for you.
Let’s look at some of the top examples of React Native apps, with real metrics where companies published them, including:
For each one, we will go over why they chose it, what they actually built, and what the numbers showed.
If you want to build a React Native app with a team that has fintech production experience, Trio has pre-vetted React Native developers ready to place in days.
React Native, created by Meta in 2015 and open-sourced almost immediately, lets developers write a single JavaScript codebase that deploys to both iOS and Android.
The appeal has always been speed and cost. Since you can get away with largely one codebase, you may be able to have one team instead of two, one codebase to maintain, and faster feature iterations.
The criticism for years was performance, since the old architecture routed all JavaScript-to-native communication through an asynchronous bridge, which introduced latency for UI updates and made certain animations and data-intensive views feel noticeably slower than fully native equivalents.
The New Architecture, which became the default in version 0.76 and the only supported option from 0.82 onward, addresses this directly. Through this, JSI (JavaScript Interface) handles communication synchronously through C++.
The Hermes JavaScript engine, now the default runtime, also compiles JavaScript to bytecode at build time rather than at runtime, delivering roughly 40% faster cold starts and 20–30% lower memory consumption compared to the previous JavaScriptCore engine.
For fintech apps specifically, those architectural improvements matter a lot.
Real-time portfolio updates, transaction feed rendering, biometric authentication flows, and chart interactions all pushed against the old bridge's ceiling, limiting products as they scaled.
The current architecture brings React Native's performance envelope close enough to native that the remaining gap rarely shows up as a user-perceptible problem.

Let’s take a look at some of the top examples of React Native apps. For convenience, they have been split into several categories.
These applications see incredibly high use and need to offer a consistent experience across multiple ecosystems.
One of the earliest high-profile adopters inside Meta was Instagram.
Instagram's team started by rebuilding the Push Notifications view as a single-feature test, since it was a low-complexity screen that validated the approach without much risk.
It worked, so they expanded.
Before React Native, their iOS and Android teams were building every feature independently, doubling effort on every release cycle. Code sharing now runs between 85% and 99%, depending on the feature.
Engineers who had never written mobile code before were shipping to production within weeks.
Instagram continues with a hybrid approach rather than a full-app rewrite, using React Native for features where shipping speed matters and native code for components where it genuinely doesn't.
Median startup times were cut in half, and a single React Native 0.79 optimization reduced time-to-interactive by 400ms on mid-range Android devices.
These days, Discord shares around 98% of its code between platforms, maintained by a relatively small mobile team.
For components where milliseconds matter, like video decoding, complex animations, and keyboard interactions, Discord drops to native Swift or Kotlin and bridges back to make sure there is no noticeable loss in performance.
Facebook created the framework and continues using it for Marketplace, Messenger Desktop, Ads Manager, Meta Horizon, and internal tools.
The original case was simple. The React web team's iteration velocity was much higher than the mobile teams', and Meta wanted to bring that short-cycle model to mobile.
The Events Dashboard rebuild cut startup time in half versus the native predecessor.
Pinterest needed fast iteration on visual discovery features like their pins, boards, visual search, and shopping, without building each feature twice.
Their approach followed Instagram's: start with one screen, validate, expand.
The initial prototype took ten days to ship on iOS and two more days to move to Android, which made the internal case effective. New features are added progressively rather than in a full-app rewrite.
E-commerce and retail applications tend to be more web-based, but mobile applications are becoming increasingly popular.
Shopify committed to React Native fully. By 2025, they had migrated their entire flagship mobile app to React Native, achieving 86% unified code while maintaining weekly release cadences throughout the migration.
They also became one of the most active ecosystem contributors, building FlashList (a high-performance FlatList replacement that surpassed 2 million monthly downloads), then rewriting it from scratch as FlashList v2 in 2025 specifically for the New Architecture.
Production screen load times consistently hit sub-500ms at P75.
Walmart rebuilt its consumer shopping app in React Native and achieved 95% code sharing between iOS and Android.
From what we have seen, this is one of the highest rates reported by any large company. For a retailer with over 150 million weekly app users, shipping features simultaneously across platforms without duplicating effort had direct business impact.
Uber Eats deployed React Native for its restaurant-facing dashboard, which hundreds of thousands of restaurant partners use daily to manage orders, update menus, and track delivery status.
The consumer app stayed fully native because maps and GPS required it, but the restaurant dashboard was a case where development velocity mattered more than raw performance.
The fintech category deserves its own section because it's where the New Architecture's improvements matter most.
Real-time data rendering, transaction processing, biometric authentication, and compliance flows all have requirements that the old bridge struggled to meet cleanly.
Coinbase rewrote its entire mobile app, utilized by 56 million users, in 2020. The new application was completed for Android by October and iOS by January 2021.
That means that it took them under a year for a complete platform rewrite, which is incredibly fast.
After the migration, they reported no performance regressions, Android ratings jumped from 3.8 to 4.4 stars (now 4.7 with 1.1 million reviews), and buy/sell/convert funnel performance improved by 80%.
They also reduced re-renders by over 90% using a custom Babel plugin. Shared utility code, like API clients, localization modules, crypto address parsers, and currency formatters, all live in NPM packages used by both mobile and web.
Bloomberg's consumer app delivers real-time financial data, market news, and personalized content to finance professionals and investors.
The component-based architecture proved a natural fit for their data-heavy UI, which was made up of financial dashboards, stock charts, and news feeds, all using reusable components that render identically across platforms.
The fact that a company with strict requirements around performance, data accuracy, and security has run React Native in production for years carries meaningful weight for anyone evaluating the framework for a financial product.
Chime powers its full iOS and Android banking apps on React Native.
Their team has not just benefited from development speed. Instead, they have also cited improvements in testing strategy, since the shared codebase makes it easier to maintain compliance-related test coverage consistently across platforms.
NerdWallet's app, which is built on React Native with TypeScript and GraphQL, manages a complex personal finance experience: credit score monitoring, card comparisons, budgeting, and financial recommendations.
The previous iOS-only app served a fraction of their addressable audience, while React Native extended Android coverage without requiring a parallel team.
Enterprise and productivity apps need to run on both mobile and web ecosystems, with real-time updates between the different apps in most cases.
Microsoft represents one of the most extensive React Native deployments in enterprise software. Office, Outlook, Teams, and Xbox all run it in production.
Some use a brownfield approach, where React Native components are embedded within existing native apps. Others, like Xbox, were greenfield builds.
Microsoft also maintains React Native for Windows, extending the framework to desktop, tablet, Xbox, and mixed reality devices.
JavaScript has the largest developer talent pool, and cross-platform features let them ship faster without maintaining three separate native codebases.
Salesforce uses React Native in the Salesforce Mobile App, which serves 150,000+ enterprise customers.
Many field sales teams use these tools daily, which sets a high reliability bar.
The security requirements, complex data models, and offline-access needs that enterprise software carries are well within what the framework handles in production.
Wix has one of the largest React Native codebases in existence, covering the main Wix app, Wix Owner, Dine by Wix, Fit by Wix, and several other products in their suite.
They're also among some of the most active open-source contributors, maintaining React Native Navigation, React Native Calendars, and React Native UI Lib.
Building and owning the tools your apps depend on gives a team direct influence over the infrastructure layer rather than waiting on third-party maintenance cycles.
Since automotive and IoT technologies have grown in recent years, it is only natural that developers are exploring React Native for their applications.
Tesla's app uses React Native to let owners remotely control their vehicle’s climate settings, charging status, door locks, location, and even service scheduling.
The 3D vehicle visualization is quite complex. It allows users to rotate and zoom an interactive model with real-time door and charging animations and runs through a custom native bridge to the Godot game engine.
For a real-time IoT control surface, the combination of React Native's cross-platform efficiency and native bridges for performance-critical visualizations has clearly worked.
Looking across these examples, several patterns appear consistently rather than in isolated cases.
Fintech is one of the strongest use cases for the React Native framework in 2026, for several specific reasons.
Cross-platform consistency reduces compliance surface. A fintech app that behaves differently on iOS versus Android creates testing complexity and potential compliance exposure.
A shared codebase makes it considerably easier to ensure that security flows, biometric authentication, and transaction confirmation screens work identically and even makes it easier to test that consistency.
The New Architecture handles the data-intensive rendering that consumer finance apps require.
Real-time price feeds, portfolio charts, transaction histories, and notification systems all involve frequent, performance-sensitive UI updates. The Fabric renderer's concurrent rendering and TurboModules' lazy loading address this more cleanly than the old bridge could.
If you're building a fintech app and need React Native developers with production experience in regulated financial environments, Trio places pre-vetted engineers in 3–5 days.
