For most of my career, web development has been my home. I’ve built and scaled applications using React, optimized frontend performance, and designed backend systems that handle millions of requests efficiently. The web, with its fast iteration cycles, universal reach, and robust ecosystem, always felt like the perfect platform for building products.
When I needed to create an application, the answer was almost always the same—spin up a React project, design an intuitive UI, connect it to a backend API, and deploy it seamlessly to users. If I wanted an app-like experience, progressive web apps (PWAs) and frameworks like React Native seemed like viable bridges to the mobile world.
I was comfortable. The web was predictable. But then I started asking myself: Am I limiting my perspective by staying in this ecosystem?
As I worked more closely with mobile teams, I began to notice something. The way they structured applications, optimized performance, and handled platform constraints was fundamentally different. I saw how certain web-first assumptions didn’t translate well to mobile. Latency, offline functionality, battery efficiency—these weren’t just afterthoughts, they were critical design concerns.
That’s when I started to rethink my approach. If I wanted to truly call myself a full-stack engineer, I needed to go beyond web and understand how native mobile apps actually work.
Why Native App Development? Key Reasons Full-Stack Engineers Should Learn SwiftUI & Jetpack Compose
As I worked more closely with native teams, I started to see the gaps in my web-first mindset. While many of the principles I brought from web development influenced the architecture of our apps, I quickly realized that the constraints of native platforms introduced new challenges that web simply didn’t have to deal with.
One of the biggest eye-openers was the app version lifecycle. Unlike the web, where we can push updates instantly and fix breaking changes on the fly, native apps have to account for users on different app versions, some of whom may not update for months. This meant that API contracts needed to be far more stable, and breaking changes had lasting consequences. Additionally, the way mobile apps interact with networks—handling requests efficiently, caching data intelligently, and structuring API calls to minimize load—required a level of optimization I hadn’t considered as deeply before.
Beyond just the technical constraints, I noticed something else. The native teams were crafting experiences that were deeply integrated with their platforms in ways the web couldn’t replicate. They took great care in designing interfaces and interactions that felt natural to iOS and Android users, leveraging platform-specific APIs, animations, and optimizations that made the app feel seamless. The ability to tailor experiences for specific devices—whether through OS-level integrations, gesture-based navigation, or hardware optimizations—was something that web technologies simply couldn’t offer in the same way.
But what struck me most was this: I had a surface-level understanding of these challenges, but not enough to truly shape the technical direction. In cross-functional discussions, I found myself waiting for the native developers to dictate the best approach rather than being able to contribute to the problem holistically. If I wanted to have real influence over the final design—ensuring the backend, web, and native layers worked cohesively—it wasn’t enough to just understand mobile development conceptually. I needed to get my hands dirty, dive deep into the intricacies of iOS and Android, and think beyond my web-centric perspective.
Energy Efficiency and Performance Favor Native Apps: A study comparing native and web apps across multiple platforms found that native apps consistently outperform web apps in both energy efficiency and resource utilization. Web apps consumed 53% more energy than their native counterparts, primarily due to higher CPU and memory usage. The overhead of running inside a browser environment led to increased resource demands, resulting in 49% higher CPU utilization and significantly greater memory consumption.
These inefficiencies stem from how web apps rely on runtime-loaded assets and browser execution layers, whereas native apps are optimized for direct hardware access. While web apps must constantly fetch and re-render content, native apps benefit from pre-compiled assets, more efficient caching, and direct API access to system resources. The study suggests that users should prefer native apps over web apps when possible to conserve battery life and improve performance.
For businesses, these findings reinforce why companies continue to prioritize native app development alongside or even over web-based experiences. Performance-sensitive applications, especially those involving streaming, social media, or e-commerce, benefit from faster interactions, reduced network overhead, and longer battery life when implemented natively. This explains why many major platforms—Spotify, YouTube, and LinkedIn among them—invest heavily in maintaining high-performance native applications rather than relying solely on web technology.

User Behavior Drives Engagement Toward Apps: A study analyzing smartphone web usage found that users rarely revisit web pages, rely heavily on search instead of bookmarks, and prefer native applications for repeated interactions. While browsers are used for ad-hoc searches and one-time visits, native apps dominate day-to-day engagement. This behavior suggests that businesses building for mobile should prioritize apps over mobile web experiences to drive retention and create seamless, high-frequency interactions.
For businesses, this shift in user behavior explains why investing in native apps is more than just a technical decision—it’s a strategic move to increase engagement, improve user retention, and create personalized experiences that keep customers coming back. Unlike web-based solutions, native apps allow companies to integrate tightly with the operating system, send push notifications, cache data intelligently, and reduce friction in ways that mobile web simply can’t match.

React Native & Flutter vs. SwiftUI & Jetpack Compose: Why I Chose Native Development
When I first considered mobile development, my natural inclination was to explore React Native or Flutter. Both are powerful frameworks that allow for cross-platform development, leveraging a single codebase to build apps for iOS, Android, and even the web. Given my background in web technologies and front-end frameworks, these seemed like the most efficient way to bridge into mobile.
However, as I dug deeper, I started seeing tradeoffs—particularly in how these tools abstract native platforms. While they are excellent for many use cases, I realized that they didn’t align with my goals of deeply understanding mobile development and delivering the best possible experience for users.
1. Why React Native & Flutter Struggle to Deliver a Truly Native iOS & Android Experience
One of the biggest challenges with cross-platform frameworks is achieving a user experience that feels truly native. Each platform has its own design system and interaction paradigms—Apple users expect apps that adhere to Human Interface Guidelines, while Android users expect Material Design conventions. React Native and Flutter do provide platform-specific widgets, but it’s difficult to match the level of detail and polish that comes with fully native development.
For example, iOS apps built in SwiftUI naturally inherit system-wide behavior like dynamic type scaling, accessibility features, and gesture-based interactions. Recreating this level of fidelity in a cross-platform framework often requires additional effort and, in some cases, custom platform-specific code—defeating the purpose of a unified codebase.
Another limitation I encountered was ecosystem integration. Native platforms provide deep integrations with system services like push notifications, background tasks, and platform-specific APIs (e.g., HealthKit on iOS or Google Play Services on Android). While React Native and Flutter offer third-party plugins to bridge these gaps, they often lag behind official native APIs or require writing native modules in Swift/Kotlin anyway.
This introduces maintenance overhead, as I’d have to keep dependencies updated, ensure compatibility with new OS versions, and sometimes rewrite logic when a plugin doesn’t fully support a feature. If I was already writing platform-specific code for key features, it made me question the benefit of using a cross-platform framework in the first place.
Every abstraction comes with tradeoffs, and cross-platform frameworks inherently introduce performance considerations. React Native runs JavaScript in a separate thread and communicates with native components via a bridge, which can introduce latency for complex interactions like animations and gesture handling. Flutter, while compiled down to native machine code, still has an abstraction layer between its UI rendering engine (Skia) and the underlying system, meaning it doesn’t directly use native UI components.
For most standard applications, these tradeoffs might be negligible. But for high-performance applications—especially those with rich animations, heavy data processing, or deep OS integrations—the cost of these abstractions becomes apparent. Many companies that initially embraced React Native or Flutter (like Airbnb and Discord) eventually migrated back to native for this very reason.
One of the most appealing aspects of React Native and Flutter is their ability to compile to multiple platforms, including the web. But in practice, this often leads to a subpar experience on all platforms rather than an optimized experience for any one of them.
A UI designed for mobile doesn’t always translate well to desktop web layouts. Touch interactions don’t always feel natural with mouse inputs. Web-specific optimizations like lazy loading, SEO, and accessibility features often take a backseat when using a mobile-first framework for web development.
Instead of getting the best of both worlds, you often end up with a solution that works “well enough” everywhere but excels nowhere. As someone who has spent years crafting highly optimized web applications, the idea of compromising the web experience for the sake of code reuse didn’t sit well with me.
Learning SwiftUI & Jetpack Compose: My Journey from Web to Native Development
Coming from a web development background, diving into native mobile development felt like stepping into a whole new world. I was used to the flexibility of JavaScript, the rapid iteration cycles of web development, and the ability to debug and deploy changes instantly. But native development? That was a different beast entirely.
The first major shift was understanding the development environment. On the web, I could spin up a React app with a few commands and see changes reflected instantly in the browser. In native development, I had to navigate Xcode and Android Studio, manage different device simulators, and deal with long build times just to test minor UI tweaks. It was a stark contrast to the quick feedback loops I had grown accustomed to.
Then came the paradigm shift in UI development. In the web world, React’s component-based architecture had always felt intuitive, but learning SwiftUI and Jetpack Compose required me to rethink how UI was structured. While these frameworks are also declarative, they introduce concepts like @State and @EnvironmentObject (SwiftUI) or remember and MutableState (Jetpack Compose) that function differently from React’s state management. Understanding how these frameworks handle reactivity and UI updates took time.
Another unexpected challenge was navigating platform-specific constraints. Unlike the web, where CSS and JavaScript provide a relatively uniform way to style and structure applications, mobile platforms enforce strict UI and interaction guidelines. Apple’s Human Interface Guidelines and Google’s Material Design patterns dictate how apps should look and behave, and deviating too much can make an app feel “off” to users. Figuring out how to balance creativity with platform conventions was a learning curve.
Performance considerations were also a big adjustment. On the web, browser optimizations and modern JavaScript engines handle a lot for you, but in native development, I had to think more deeply about memory management, background tasks, and CPU efficiency. Things like managing view hierarchies efficiently, avoiding unnecessary recompositions, and handling network requests in a way that optimized battery life became crucial.
And then there were platform-specific APIs and lifecycle management. Web applications don’t have to deal with app lifecycles in the same way mobile apps do—managing state across foreground, background, and terminated states was a whole new challenge. I had to learn how to properly handle deep linking, push notifications, and background data sync without causing excessive resource consumption or draining battery life.
Despite these struggles, there were also moments of clarity. The first time I successfully built a SwiftUI view that adapted seamlessly across different screen sizes, or when I figured out how Jetpack Compose made complex UI interactions feel effortless—these moments reminded me why I embarked on this journey.
It wasn’t easy, but every challenge pushed me to think differently, and every struggle reinforced why understanding native development was critical. Instead of simply consuming mobile APIs as a web developer, I was now seeing how these platforms actually work under the hood—and that insight was invaluable.
How Learning Native Development Made Me a Better Full-Stack Engineer
Learning native development hasn’t just expanded my skill set—it has fundamentally changed the way I approach software engineering as a full-stack developer.
Before diving into mobile, my focus was largely on optimizing backend systems and building seamless web applications. I thought about API design from a web-first perspective, ensuring fast response times, efficient database queries, and a smooth client-side experience. But working on native mobile applications introduced a whole new layer of considerations that I hadn’t fully appreciated.
One of the biggest shifts was understanding how mobile apps consume APIs differently from web applications. Unlike web clients that typically make frequent requests and reload content dynamically, mobile apps need to be far more deliberate about network usage. Constraints like limited connectivity, battery efficiency, and app lifecycle management mean that APIs need to be designed with offline access, caching strategies, and efficient data synchronization in mind. I now think beyond just optimizing API response times—I consider how data should be fetched, stored, and refreshed based on how mobile apps actually operate in the real world.
Another key insight has been how UI performance is tightly coupled with backend design in mobile applications. In web development, rendering performance issues can often be mitigated with frontend optimizations like lazy loading and client-side caching. But in mobile, inefficient rendering can lead to sluggish interactions, high memory consumption, and degraded user experience—especially on lower-end devices. Learning SwiftUI and Jetpack Compose has helped me better understand how the structure of backend responses affects the performance of UI rendering on mobile, reinforcing the need for APIs to deliver efficiently structured, minimal, and mobile-optimized data.
From a technical leadership perspective, my deeper knowledge of mobile development has also improved cross-functional collaboration. Before, I relied on mobile developers to surface constraints and challenges, often deferring to their recommendations on how best to integrate with backend systems. Now, I can actively contribute to those discussions, ensuring that decisions are made with a holistic understanding of how backend, web, and native layers interact. Instead of designing APIs purely from a backend or web-first mindset, I now think about how those APIs will be consumed across all platforms and optimize accordingly.
This journey into native development has made me a more well-rounded engineer, bridging the gap between frontend, backend, and mobile in a way that allows me to architect more cohesive, scalable, and performant systems. It’s no longer just about writing code—it’s about understanding how the entire ecosystem fits together.
Should Full-Stack Engineers Learn Native Development? My Take on SwiftUI & Jetpack Compose
If you’re a full-stack engineer or a web developer considering native mobile development, the short answer is: it depends on your goals.
If your primary objective is to quickly launch a mobile app, then sticking with web-based solutions like PWAs or cross-platform frameworks like React Native or Flutter might be the right choice. These technologies lower the barrier to entry and allow you to reuse much of your existing skill set.
However, if you’re looking to deeply understand how mobile platforms work, optimize app performance, and build experiences that feel truly native, then learning SwiftUI and Jetpack Compose is absolutely worth it. It forces you to think beyond the abstractions of cross-platform tools and web-first mentalities, giving you direct control over how your apps integrate with the operating system, interact with hardware, and manage resources efficiently.
For me, the biggest benefit has been the shift in perspective—I now approach software development with a broader, more holistic understanding. I no longer see mobile as just another frontend client; I see it as a platform with its own unique constraints, opportunities, and tradeoffs. That shift has made me a better engineer, not just for mobile, but for backend and web as well.
Would I recommend this path to every web developer? Not necessarily. But if you want to be a truly end-to-end full-stack engineer—one who can build for web, backend, and mobile in a way that considers the entire ecosystem—then yes, investing in native development is a game-changer.
