A few years back, hybrid apps built with Ionic, PhoneGap and Cordova were a perfect and cost-effective alternative to native mobile apps development.
However, with technology moving forward, they might not meet users’ expectations anymore. React Native is a good alternative that can save your app from going under.
What is hybrid app development?
What is Ionic?
Ionic has many pros and the most important one appears on its official site - you can create mobile apps without knowing platform-specific features. Moreover, you can use a wide range of components - building-blocks that adjust to the platform so that your app can imitate the native one.
To integrate with the platform's specific features, like Bluethooth or camera, you can use plugins provided by Ionic - it makes adding native functionalities to your Ionic mobile app easy.
The most important disadvantage is the performance - Ionic runs in a WebView, which makes Ionic apps relatively slow.
Secondly, although Ionic’s components adjust depending on the platform, sometimes additional work is required to provide a more native feel.
Security is the next thing you should take care of - secure your app like you would do it for web & mobile. You should also check what native features you need - not all of them are supported by plugins. If you don’t find an adequate plugin, then you have to write the code for both platforms. The last thing you should be aware of it’s debugging, which is quite complicated, so fixing bugs can be problematic.
What is Apache Cordova?
Apache Cordova is an open-source mobile cross-platform development framework. Like in the case of Ionic - it lets you build mobile apps using standard web technologies. Apps created using Apache Cordova execute in a WebView within the native application wrapper, the same as Ionic.
The cons of Apache Cordova are similar to those of Ionic. Code running in WebView will always suffer from worse performance. Additionally, Apache Cordova doesn’t provide the kind of components Ionic does, so it has even less of a “native feel” than Ionic.
What is PhoneGap?
PhoneGap framework is a distribution of Apache Cordova. That means it’s powered by Apache Cordova, but has some extra stuff (i.e additional tools) from the Adobe team.
The basic tools are free to use, but Adobe offers more services, like for example the “PhoneGap Build Service”, which helps you get apps ready to be published on the App Store and Google Play Store without maintaining native SDKs. Adobe’s PhoneGap Build Service does this work on their side by compiling apps in the cloud (keep in mind that this service is not free).
Pros & Cons
As Apache Cordova and PhoneGap are practically the same, the pros & cons are also similar. What can be a plus of PhoneGap is that Adobe provides additional tools that you can use together with PhoneGap (like the before mentioned PhoneGap Build Service, and others: PhoneGap Developer App, the PhoneGap Desktop App, and PhoneGap Enterprise).
What is React Native?
React Native has the most of the advantages among the solutions mentioned in this article. Using React Native you create cross-platform mobile apps. React Native ensures fairly good performance, and if your app is well designed and written, it can be indistinguishable from a native one. Native UI controls for sure contribute to this. Because view components are converted to native ones (they change their appearance depending on the platform), the UI has a native feel.
React Native has a huge community, so in case of any trouble you can easily find help from other app developers. You can also find many libraries - ready-made solutions for custom needs from the React community that you can use in your app to avoid creating features from scratch.
There are many packages that allow you to integrate with platform-native features and if you don’t find a ready-to-use solution, you can easily write your own native module (but this would require knowledge of the native programming language).
In comparison to the other cross-platform solutions mentioned in this article, we cannot point out any cons (React Native solves all the problems other solutions have); we can, however, name a few disadvantages compared to native apps.
The low entry threshold is both a plus and a minus - without good experience in React it is easier to make mistakes that can have a big impact on performance than in the case of native apps.
React Native is also not recommended for apps where security is really important (for example financial apps). Native solutions will always be more secure. If you plan to integrate with many native features, it’s also good to consider choosing native - React Native has many ready solutions, but they can’t cover all features. A React Native app may also not scale as well as a native one.
Differences Between Ionic vs Cordova vs PhoneGap vs React Native
React Native comes with better performance and smoother animations. In most cases using React, we can build mobile apps truly indistinguishable from apps built using Objective-C (native iOS apps) or Java (native Android apps)
|Example||React Native||Hybrid-Web, Cordova, PhoneGap|
|Languages||JS + JSX for views||HTML + CSS + JS|
|Code Reuse||Shared codebase, in rare
cases differences in the UI
codebase depending on the
|One codebase: business logic & UI codebase|
|Target Platforms||Mobile platforms: Android & iOS||iOS and Android, mobile and desktop browsers as a Progressive Web App|
|Investment||Medium (but still smaller than native solutions)||Lowest|
|UI Elements & Native Feel||Ul controls are rendered as native controls, for example React Native's Image component will be converted to Image View on Android and Ullmage View on iOS, improving the native feel||Web Ul elements - sometimes look differently depending on the platform, less of a native feel than in the case of React Native|
|API Access / Native Features||Built-in modules give access to native features like the camera; for more custom solutions you can search for modules from the React Native community or write your own||No built-in support for native features; possible access through plugins (options to write custom ones)|
|Performance||Mostly indistinguishable from native solutions||Lower than native & React Native|
Risks related to staying with Ionic, Cordova or PhoneGap
The biggest problem with hybrid apps is their performance. The web was originally built for web pages, not the complex apps we produce today. Hybrid apps are going to run just fine on high-end phones but still not as smoothly as you would want. Low-end phones are where the biggest problem lies.
High user expectations
Most smartphone owners spend the majority of their time using only a few apps, and they expect any new app to be as polished as Facebook, YouTube, or Uber.
With high user expectations, hybrid apps can’t live up to such benchmarks. They offer poorer user experience with slower animations, lack of platform-specific gesture recognition, and keyboard misbehaviour.
More room for error
Another problem is that building a hybrid app, you automatically inherit all the issues that the web has. This means bugs that only appear in one or more browsers or styles working differently across different browsers.
Low popularity among big players
Another thing that the popularity of hybrid apps is on the decline. Both PhoneGap’s and Ionic’s showcases demonstrate a noticeable shortcoming in premier apps.
In contrast, the list of apps that have migrated or partially migrated from hybrid/native to React Native is long. The list includes Facebook, Instagram, Skype, and many others. It would be quite challenging to find a high-end app that has moved from native to hybrid.
Why to choose React Native? Main benefits of RN over Ionic/Cordova/PhoneGap
The biggest benefit that React Native offers is its much better performance than in the case of hybrid apps.
In React Native, all views are native, so apart from higher efficiency, you get the native feel with super smooth animations. On top of that, the hardware functionalities are processed by the specific platform and not by Cordova. React Native renders native views without using Webview, so you don’t have to worry about any problems with browser compatibility.
Finally, React Native is based on React, a framework with much better support – both from Facebook and the community. Thanks to the ongoing support, React Native stays up-to-date, offers higher reliability, and gives you a superior knowledge base, where you will be able to find out how to develop apps and solve problems.

React Native gives you the advantage of hybrid apps – that is cost-effective multiplatform development – but doesn’t bring along their disadvantages such as sluggish performance or poor user experience.
React Native has already been adopted by many big players such as Uber or Instagram, which is a social proof for its reliability. Nowadays, a successful mobile application should be fast and highly responsive. Otherwise, users will abandon it.
Building hybrid apps was good in the past, when we had limited resources and the technology wasn’t mature enough yet, but now, when we have React Native, I wouldn’t take the risk of developing an app in Ionic/Cordova/PhoneGap and would move my app to React Native instead. We can help you do this!
