The document discusses react native mobile apps, highlighting their native compatibility, high performance, and ability to utilize phone features, but notes the high cost of development due to platform-specific requirements. It addresses various performance issues such as slow launch times, memory leaks, and large app sizes, providing recommendations for improvement. It also includes contact information for further inquiries.

1. React Native
Mobile App

3. What Are The Native Mobile Apps?
A programming language specialized to a specific operating system, such as
Objective C for iOS or Java for Android. A react native mobile app provides a
high level of performance and consistency. They can also use the phone’s
various features, such as the camera and address book. Furthermore, it can
use many applications without an online connection. On the other hand, such
an application is costly to produce since it is linked to a single operating
system, forcing the developer to generate duplicate copies that run on other
platforms.

4. React Native Performance Issues & How To Solve Them
Navigation issues
The core react native development team has had to
experiment a lot with navigation since the launch of React
Native to eliminate the inconsistencies between JS & native
thread bridging. There are also a few speed concerns with
React Native page browsing that need to be addressed.

5. Launch time
A slow app start time might result in a small number of inactive
users. It’s the most significant contributing factor to user
retention. The default implementations of React Native are a vital
source of slow app performance and delays in app launch times.
We recommend that you take care of the Object. Finalize
elements to enhance the app’s starting time. Since finalizers
execute on a single thread, all other objects must wait until all
finalizers have passed. There are a lot of dependencies, which
cause a long wait for the app to launch.

6. Memory leakage
Memory leaks in your react native app can occur for a variety
of reasons. Take, for instance, scrolling in a hybrid Android
music application. When you browse down the music list to
the third page, the app freezes up RAM on your phone and
gradually affects performance. Because both processes are
performed on separate portions (one in native, the other in
react native js), information is sent between them over a
bridge, which takes a long time.

7. Large app size
A more extensiver application size will have a significant
impact on the application’s performance. It is a typical issue
with Android apps, which are extremely sensitive to third-
party sources, different displays, libraries, and other factors.
These additional resources have a direct impact on the
application’s size, increasing it.
