Here is the Updated List of 11 Popular Apps built with Flutter

1. BMW App (My BMW)

Before Flutter
Before the launch of the My BMW app, BMW’s connected vehicle experiences were mostly built with native iOS development, with Android to be handled in a separate way.

This method results in: 

• Gaps in features between iOS and Android versions
• More effort was required to maintain consistency across different platforms
• Slow updates of connected-car features worldwide

After Adopting Flutter

Around 2020–2021, BMW completely rebuilt its My BMW app through the use of Flutter and Dart to work across both iOS and Android from a unified platform. 

What changes came out:  

• Unified development for both platforms
• Same feature available across iOS and Android

Solution: Flutter made it easy for BMW to move from a platform-heavy native setup to a shared mobile architecture, enabling the firm to maintain feature variance and provide aconsistent connected-car experience across various regions without hiring additional team. 

2. The New York Times

Before Cross-Platform Framework Expansion

The New York Times was initially using platform-specific and React-based architectures around their digitalized products:

• They were deploying React Native for core mobile applications to deliver near-native performance
• React + GraphQL powered the main NYTimes.com web experience
• Additional teams and stacks were needed for mobile and web experiences

Problem: This method delivered a high-end performance, but it needed a development team and efforts at large, with careful coordination between platforms.

After Adopting a Multi-Framework Strategy
Later, NYT expanded its digital services, focused more on Flutter for select, highly interactive or experimental cross-platform initiatives, while continuing to depend on React and React Native for major products.
This resulted in:

• Faster prototyping for new interactive experiences
• More easy for experimentation among mobile and web
• Reduced overhead for non-core, feature-rich applications

Solution: Instead of removing its current stack, The New York Times decided to go with Flutter, taking React and React Native, selecting the right framework based on product needs. This flexible practice allows NYT to innovate quickly. 

3. Nubank

Before Standardizing on Flutter

Initially, for their mobile architecture, Nubank was heavily dependent on a combination of native development and React Native:

• Native Android (Kotlin) and iOS (Swift) for important banking features
• React Native for shared UI and fast feature delivery
• Several codebases lead to more maintenance effort

Problem: With the expansion of the product, this approach made it really difficult to keep consistency and roll out updates faster across platforms.

After Adopting Flutter As The Main Model

Between 2019 and 2020, Nubank transform their mobile apps to Flutter as the main framework.

This shift allows them to:

• A shared Flutter codebase for most new features
• Faster development and release cycles
• Improved consistency across Android and iOS experiences

By 2021–2022, Nubank focused to go with a mixed environment, where:

• New features were built in Flutter
• Legacy modules written in native or React Native were migrated easily

Solution: Due to this, Nubank has been able to maintain mobile development without facing any risk, supporting gradual migration while keeping millions of users engaged with their app. 

4. ByteDance (TikTok, Lark, Douyin & Others)

Before a Unified Cross-Platform Strategy

With the expansion of ByteDance’s product portfolio, mobile development is based heavily on:

• Native iOS and Android for performance- based features
• React Native–style solutions for shared UI and quicker iteration
• Multiple frameworks across teams, enhancing architectural fragmentation

Problem: This worked at broade scale, but challengeswere there around productivity and consistency.

After Adopting a Multi-Framework Model

ByteDance evolved toward a best-tool-for-the-job approach, combining Flutter, native code, and in-house frameworks:

Flutter

• Most heavily used in Lark, which ByteDance has cited as a successful Flutter adoption.
• Successfully deployed across several new or smaller apps to improve development speed.

Native (Swift, Kotlin, C++)

• Retained for high-performance video rendering and playback in TikTok and Douyin

Lynx (In-House Framework)

• Developed to address limitations seen in React Native
• Used for dynamic, web-technology-driven UI and feature modules

Solution: Rather than focusing on a single framework, ByteDance aims for scale, performance, and developer efficiency. To increase productivity, Flutter is the main framework,d whereas native code and Lynx handle performance-critical tasks conveniently.

5. Xianyu (Alibaba Second-Hand Marketplace)

Before Standardizing on Flutter

During the initial days of development, Xianyu adopted native Android and iOS development, with H5 (HTML5) utilized for various activities and marketing pages.

This leads to:

• Slower iteration on high-traffic product pages
• Higher maintenance cost for duplicated native UI logic
• Limited efficiency for rapid feature development

Problem: The team evaluated multiple cross-platform options, along with React Native, during this stage. 

After Adopting Flutter in a Hybrid Architecture
Later inbetween 2018 and 2019, Xianyu adopted Flutter as its core framework, saying that Flutter wins over the line and provides commendable performance. 
Key changes included:

• Migration of core flows (main feeds, search, and detail pages) to Flutter
• Adoption of a Native + Flutter hybrid model, not a full rewrite
• Deep integration using FlutterBoost, a hybrid routing and integration framework developed by the Xianyu team

Solution: By deploying Flutter into a native foundation instead of completely replacing it, Xianyu achieved higher development efficiency on high-traffic pages while preserving the stability and control of native systems.

6. Hamilton (Official Broadway Musical App)

The Hamilton app was also developed by deploying Flutter to deliver a high-quality, consistent experience across iOS and Android from a single codebase. Flutter was still emerging, but the team needed speed, performance, and design consistency without maintaining two separate native apps.

Built with Flutter
The app was developed by Very Good Ventures (formerly Posse) and became:

• The first commercial app built with Flutter outside Google
• Completed in just three months
• Launched even before Flutter 1.0, showing evidence of the framework’s production readiness

What Flutter Enabled

• One shared codebase for iOS and Android
• Smooth performance and polished UI

7. Headspace (Mental Wellness Platform) [2026-Update]

Before Adopting Flutter

Headspace was earlier focusing on native codebases for iOS, Android, and web. But as a result, this approach enhances their development cost at major updates, and feature updates are slow.

Why Headspace Chose Flutter
To make the process of development easy and deliver a consistent experience, Headspace made a strategic decision to migrate to Flutter. The goal was to move toward a unified, cross-platform codebase without compromising quality or performance.

Flutter in Production

• Newer features like the AI companion Ebb and mental health coaching services are already built with Flutter.
• Active hiring of Flutter engineers to improve the shift
• Shared UI and logic across mobile and web platforms

Outcome & Vision
Flutter allows Headspace to streamline development, reduce maintenance costs, and deliver a consistent, high-quality wellness experience to millions of users worldwide.

8. Google Pay 

Before the Flutter Rewrite
Before 2020, Google Pay was using separate native Android and iOS codebases:

• Independent platform teams were creating duplicate solutions
• Feature rollout needs development and testing 
• UX differences reflected across regions and devices

Problem: As Google Pay grows worldwide, mainly in high-growth markets like India, this framework has become increasingly difficult to scale efficiently.

After Rebuilding with Flutter

At the start of 2020, Google transformed its Google Pay app using Flutter as the main framework.
This transition resulted in:

• A single shared codebase across Android and iOS
• An app that is approximately 35% smaller
• Engineering time savings of roughly 60–70%

The Flutter-based Google Pay app now represents one of the largest production deployments of Flutter, particularly across India, Singapore, and global markets.

Solution: Flutter enabled Google Pay to consolidate mobile development at scale, improving consistency and velocity while supporting the demands of a globally distributed financial application

9. eBay Motors (Automotive Marketplace App)

Why Flutter Was Used
As the main eBay app is not really built with Flutter, eBay opted for using Flutter for its eBay Motors app to boost the development and provide a consistent experience around iOS and Android from a shared codebase. 

Built with Flutter

The eBay Motors app was developed using Google’s Flutter UI toolkit, focusing on speed, scalability, and cross-platform consistency for vehicle buying and selling.
