Pros and Cons To Build The Perfect Mobile App
React Native vs Native App Development (iOS & Android): Pros and Cons To Build The Perfect Mobile App
React Native is quickly becoming popular amongst mobile app developers, but it still needs more time to catch up with native app development.
However, it still lacks supporting the native look and feel of iOS and Android apps. Complex mobile apps also require the help from native Android and iOS developers.
Should mobile developers use React Native or Native App to design the perfect mobile app?

According to the popular mobile app developer Dino Trnka, the answer depends on your project:
- If you need to make an iOS-only or Android-only app, choose Native app development.
- If you have a small team with limited time and resources, and need to make an app for both platforms, choose React Native.
- If you need to make a highly complex app that utilizes a large portion of platform-specific code, choose Native app development.
- If you want to take advantage of fast build time, and features such as hot reloading and live reloading, choose React Native.
- If you plan to maintain the app over a long period of time, without fear of Facebook quitting React Native, choose Native app development.
- If your developers have a strong React / Web development background, choose React Native.
- If your app needs to support new mobile OS features as soon as they are released, choose Native app development.
- If your app is going to look and behave the same on both platforms, choose React Native.

Pros and Cons of React Native
Pros of React Native
1. Faster to Build
The major selling point of React Native is the shorter development time. The framework provides numerous ready-to-apply components that can accelerate the process.
As the RN community is growing and Facebook regularly introduces new updates, we may find ready components for most of the solutions we need one day.
We built the very same app with both React Native and Swift. The latter took as much as 33% more time to build and still was working only on iOS – with no Android version. Significant savings can come with developing for more than one platform. As RN lets you share a big part of a codebase between operating systems within a few hours, you can potentially save time and money.
2. One Framework, Multiple Platforms
React Native allows you to reuse the codebase (or just a part of it) between iOS and Android. In practice, full cross-platform development is possible to some extent, depending on how many native modules you use in your application.
Some features will be available in npm packages, but others will need to be written from scratch. It will only get better, though. React Native community actively supports the framework, adding new tools to its open source.
Whereas the stability of such solutions still leaves a lot to be desired, the possibility of sharing non-UI dependent code might still bring reasonable benefits. Besides shortening the development time, it could help improve the consistency of your app’s business logic between all supported platforms.
3. Quick Refresh
The React Native team seems to be listening to the community’s voice carefully. One of the top React Native pain points was that the Hot Reload feature was broken. Most developers had it turned off as it was unreliable. The response to these complaints is Fast Refresh. This tool, released at the end of 2019, fixes all the issues that Hot Reloading has and provides a great developer experience that speeds up both building new features and bug fixing.
4. Smaller Teams
Native development requires two separate teams for Android and iOS. It can hamper the communication between developers and, accordingly, slow down the development. Native Android and iOS teams have their own projects, and they often have different development speeds and methods. As a consequence, two projects can easily become inconsistent. It can lead to differences in the app’s implemented features, behaviour and appearance.
5. Fast Applications
We ran a test and compared two versions of a simple application, written in React Native and Swift. Both apps achieved very similar performance results. Differences in performance were slight, almost unnoticeable to an average user. In the case of more complex applications, the framework might be less efficient, but you can always transfer some code to a native module, and it won’t be an issue anymore.
6. Simplified UI
React Native is solidly based on creating a mobile UI. In native development, you will need to create a sequence of actions in the application. RN employs declarative programming in which such an order of implementing actions is obsolete. As a result, it is much easier to spot bugs on the paths a user can take.
7. Large Developer Community
Cons of React Native
1. Compatibility & debugging issues
While it may come as a surprise – after all, React Native is used by top tech players – it’s still in beta. Your developers might come across various issues with package compatibility or debugging tools. If your developers aren’t proficient in React Native, this might negatively impact your development as they spend time on troubleshooting.
2. Lack of Some Custom Modules
Despite its maturity, React Native still lacks some components. Others, in turn, are underdeveloped. The chances are you won’t have a problem with that, as the majority of custom modules you need are available, well-documented, and working properly.
However, it might happen that you will have to build your solution from scratch or try to hack an existing one. When developing your custom modules, you could end up with three codebases (RN, Android, and iOS) for a component instead of only one. In each of those codebases, there can be differences in behaviour and appearance. Fortunately, those situations don’t come about often.
We had problems with making shadows work in our React Native application, as the custom library was only available in a beta version. Therefore, we decided to write our own custom solution to make it look the same as it was in the native application.
3. Native Developers Still Needed
Implementing some native features and modules necessitates having detailed knowledge of a particular platform. The lack of out-of-the-box support for many native app functionalities (e.g. push notifications) used to be a significant issue with React Native development.
As the community grows, more and more open-source libraries provide easy access to native platform features. Nevertheless, the implementation of some more advanced features might still require help from iOS and Android developers.
Their input depends on the complexity of your project, but you need to bargain for them when kicking off with React Native. This might be an issue for small teams, in which developers don’t have any native mobile experience.
What is a Native App?
Native app development refers to building a mobile app exclusively for a single platform. The app is built with programming languages and tools that are specific to a single platform. For example, you can develop a native Android app with Java or Kotlin and choose Swift and Objective-C for iOS apps.
Native apps are known to deliver exceptional user experience as they are generally high performance. User experience is also enhanced as the visuals are tailored to the platform UX. However, startups are concerned about the high cost of native app development as they need to run concurrent development for both platforms.
Pros and Cons of Native App Development
Pros Of Native App Development
1. Broad Functionality
You’ll have access to every API and tool provided by the platform that you’re working on. Technically, there are no limits on how the programmers could work with the new app.
2. Better Store Support
A native app is easier to be publish and usually ranked higher on the platform’s app store because it delivers better performance and speed.
3. Increased Scalability
Apps built for the native environment also tend to be more scalable, thanks to the flexibility in resources management and the array of tools available.
4. High Performance And Great UX
The direct interaction between the code and the underlying resources results in high performance. Also, native apps generally have a better UX that is synonymous with the platform.
Cons Of Native App Development
Building native apps can be costly when you need to launch for both iOS and Android. It means you’ll need to deploy two teams working on different platforms.
2. Time Consuming
Native app development is time-consuming as the work done for a platform cannot be duplicated for another. Instead, a separate team is needed to work on the other version.
While native iOS and Android are here to stay, and they will remain with us in the foreseeable future, the future of React Native is uncertain. While React Native tends to keep up with the native trends, there will always be a time gap between some new feature (Face ID for example) emerging on the native platform and the same feature being included in React Native. This means that developing anything using fresh technology will take more time.
