In any case, the most principal contrast between React Native/Xamarin and Ionic is the sort of application being made. Ionic performs hybrid improvement: you make a site utilizing CSS/HTML and afterward coordinate it with a mobile application.
Its appearance is the same as projects’ you can discover on Google Play or AppStore. Along these lines, it tends to be downloaded and introduced giving the comparable client cooperation as local. In reality, most clients scarcely comprehend the contrast among local and hybrid applications.
Ionic is a sensible answer for prototyping and quick advancement, or for structure a multi-utilitarian application with least changes in the code base. In this manner, you can cover a few platforms out of a similar code base in a short measure of time.
The made programming is shown indistinguishably paying little mind to the OS you have chosen. It is conceivable to gain admittance to explicit mobile usefulness (for instance, camera, rundown of contacts or GPS sensors) with the assistance of PhoneGap or Cordova.
Concerning React Native and Xamarin, applications are created to be perfect with any chosen mobile platform. The local parts incorporated with the systems enable them to basically “feel” local. Aspiring mobile app designer should be familiar with both these platforms.
In this manner, everything a client can find in the React Native/Xamarin-based application will be shown in a way as close as conceivable to the local one relying upon the particular prerequisites of every mobile platform. Much of the time, precisely this style of improvement gives higher execution and responsiveness in correlation with hybrid applications.
An Ionic Survey 2017 exhibits the hybrid way to deal with structure mobile applications is surpassing local advancement. Two years back, 20 percent of developers overviewed were assembling only with local devices.
Until this point, the outcomes have diminished to 2,9 percent. Correspondingly, a little more than 32 percent of developers studied depend on hybrid-constructed applications rather than local.
What are the detectable contrasts of cross-platform and local application execution?

Respond Native (JavaScript) versus Native (Swift)

John Calderaio, Full-Stack Software Engineer, created two iOS applications to think about the execution of local iOS (Swift) and React Native. In the examination, he demonstrates how the essential components of the equivalent application are actualized utilizing hybrid and iOS local improvement. He further measures and looks at CPU, GPU, and memory utilization of eaсh application to see which one performs

The mobile applications John worked with React Native and Swift have a practically indistinguishable physical appearance. To the extent execution benchmarks are concerned, the React Native form utilized CPU less successfully (by over 10%), however, profited by GPU use and involved less memory than Swift.

Xamarin (C#) versus Native (Objective-C and Java)

Kevin E. Passage, a mobile designer, chose to contrast platform execution while building and Native, Cordova, Classic Xamarin, and Xamarin.Forms structures. He made test applications with various structures for the two iOS and Android platforms and offer the outcomes on his blog (2014, 2015).

The extent of the application affects how much transmission capacity it takes to convey and influences the heap time. As per Kevin, Xamarin demonstrates the additional size required into in the overhead of the.Net structure.
Therefore, local advancements demonstrated the quickest burden times. In any case, applications worked with Classic Xamarin stacked almost as quick likewise with local dialects.
In this test, Kevin stacked 1000 records from Azure Mobile Services to gauge how quick information stacked from an outside administration. He was paralyzed to see Xamarin show the best outcomes.
The last test estimated a CPU concentrated task. It was amazing that Xamarin performed superior to local dialects: Objective-C lost essentially; Java was inside 0.2-second edge behind.

Ionic 2 versus React Native

So as to think about Ionic 2 and React Native execution benchmarks a few corporate applications for iOS and Android platforms were made. The designer tried CPU and memory use on the two platforms and gives the accompanying outcomes:
Subsequently, Ionic 2 gave essentially more unfortunate outcomes in all testings with the exception of memory use on Android.
