In the evolving landscape of mobile app development, the debate between hybrid vs native app development continues to be a pivotal discussion. Native app development involves writing code specifically for each mobile device's platform, leveraging its full potential to create natively optimized apps. This approach offers high performance and a seamless user experience but requires more resources to build apps for multiple platforms.
On the other hand, hybrid app development utilizes a single code base to build apps that run on multiple platforms, often through an open source framework. This method significantly reduces development time and costs, making it a popular choice among mobile app development companies looking to efficiently deploy across iOS and Android. However, it may sometimes compromise on the app's performance and user experience compared to native apps.
Looking towards the future, cross-platform technologies are emerging as a formidable solution, blending the best of both worlds. These technologies enable building mobile apps that perform nearly as well as native apps while maintaining the efficiency and cost-effectiveness of hybrid approaches. The top cross-platform app development companies in 2024 are likely to leverage these technologies to deliver high-quality apps that meet the diverse needs of users across all platforms, highlighting the pros and cons of each approach while pushing the boundaries of mobile app development.
How Companies Save Budget with Flutter
California-based Ptolemay regularly cuts development costs by 30–40% for clients by leveraging Flutter’s single codebase. Instead of hiring separate iOS and Android developers, they assemble one cross-functional team, coding features once and deploying across multiple platforms. This approach slashes both initial and long-term expenses, freeing funds for marketing, user acquisition, or scaling additional features.
Maintenance also gets easier and cheaper when you only have to fix bugs or add features in one place. According to one Ptolemay project lead, “A single Flutter codebase keeps our clients agile. They can respond to feedback in days rather than weeks, ensuring faster growth without ballooning budgets.” By avoiding platform-specific roadblocks, startups can ship new iterations swiftly, capturing feedback and iterating again in near real-time.
Real-world examples reinforce these cost and time savings. Nubank, a major digital bank, shrank a year-long development cycle to three months using Flutter. Meanwhile, Alibaba’s Xianyu marketplace noted a 75% drop in feature release times, directly impacting customer satisfaction and revenue. Though built by larger corporations, the same principle—one codebase, fewer engineers, reduced maintenance—applies perfectly to any early-stage startup aiming to scale.
Teams also love Flutter for its near-native performance and seamless user experience. By rendering UIs directly, apps feel smooth without sacrificing speed. That means fewer support tickets, less churn, and more positive reviews—critical factors for any startup’s growth.
Overall, Flutter’s cost benefits revolve around unified code, accelerated development cycles, and simplified maintenance. For founders juggling tight budgets and aggressive milestones, those advantages often tip the scales, transforming a daunting development plan into a streamlined path to MVP and beyond. By partnering with experts like Ptolemay—or building an in-house Flutter team—startups can maximize resources while still delivering polished, high-performance apps that impress users across platforms.
Cross-Platform App Development FAQs (2025)
How does cross platform app work?
A cross-platform app works by using a single codebase to run on multiple operating systems like iOS and Android. Frameworks such as Flutter or React Native compile the shared code into native components, ensuring a consistent look and feel.

Native development can deliver optimal performance and tight integration with a device's hardware and software. However, cross-platform solutions are often faster to build and maintain, making them a smart choice for most use cases. For example, complex games with intensive graphics may favor native, while general business apps thrive with cross-platform frameworks.
What is the best language for cross platform apps?
The best language depends on your chosen framework, but popular options include Dart (for Flutter) and JavaScript or TypeScript (for React Native). Each offers robust communities, libraries, and tooling for efficient development. For instance, Dart excels in hot reload and performance, while JavaScript remains widely adopted and easy to learn.
Is cross platform the future?
Cross-platform development is likely to remain a strong trend, thanks to its cost-effectiveness and swift deployment. As frameworks like Flutter and React Native evolve, they increasingly match native performance and user experience. For example, many businesses now prioritize cross-platform solutions to reach broader audiences faster without sacrificing quality.
Which is better, Flutter or Ionic?
Flutter offers fast performance using the Dart language and its own rendering engine, providing near-native speed and smooth UIs. Ionic relies on web technologies (HTML, CSS, JavaScript) and is easier for web developers transitioning to mobile. For instance, Flutter suits complex, graphics-heavy apps, while Ionic excels at quickly building simpler, content-driven applications.
