A compelling reason for using React Native instead of WebView-based tools is to achieve 60 frames per second and a native look and feel to your apps. Where possible, we would like for React Native to do the right thing and help you to focus on your app instead of performance optimization, but there are areas where we're not quite there yet, and others where React Native (similar to writing native code directly) cannot possibly determine the best way to optimize for you and so manual intervention will be necessary. We try our best to deliver buttery-smooth UI performance by default, but sometimes that isn't possible.
A compelling reason to use React Native instead of WebView-based tools is to achieve 60 frames per second and provide a native look and feel to your apps. Whenever feasible, we aim for React Native to handle optimizations automatically, allowing you to focus on your app without worrying about performance. However, there are certain areas where we haven't quite reached that level yet, and others where React Native (similar to writing native code directly) cannot determine the best optimization approach for you. In such cases, manual intervention becomes necessary. We strive to deliver buttery-smooth UI performance by default, but there may be instances where that isn't possible.

This guide is intended to teach you some basics to help you to [troubleshoot performance issues](profiling.md), as well as discuss [common sources of problems and their suggested solutions](performance.md#common-sources-of-performance-problems).

title: Performance Overview

A compelling reason for using React Native instead of WebView-based tools is to achieve 60 frames per second and a native look and feel to your apps. Where possible, we would like for React Native to do the right thing and help you to focus on your app instead of performance optimization, but there are areas where we're not quite there yet, and others where React Native (similar to writing native code directly) cannot possibly determine the best way to optimize for you and so manual intervention will be necessary. We try our best to deliver buttery-smooth UI performance by default, but sometimes that isn't possible.
A compelling reason to use React Native instead of WebView-based tools is to achieve 60 frames per second and provide a native look and feel to your apps. Whenever feasible, we aim for React Native to handle optimizations automatically, allowing you to focus on your app without worrying about performance. However, there are certain areas where we haven't quite reached that level yet, and others where React Native (similar to writing native code directly) cannot determine the best optimization approach for you. In such cases, manual intervention becomes necessary. We strive to deliver buttery-smooth UI performance by default, but there may be instances where that isn't possible.

This guide is intended to teach you some basics to help you to [troubleshoot performance issues](profiling.md), as well as discuss [common sources of problems and their suggested solutions](performance.md#common-sources-of-performance-problems).
