Suppose you don't need to create any custom components in your React Native project, and at the same time, you want your mobile (or web) application to look professional and be user-friendly. In that case, you can use a component **library or UI toolkit**.

React Native UI toolkit or component library can be really useful during mobile application development. It provides ready-made solutions such as interface elements or APIs and lets us focus on the app's business logic cutting back user interface development time. 
 
A few component libraries on the market currently provide a selection of components, icons, typography, themes, and web support. In this article, I'll tell you a bit about UI libraries. This will give you an overview of them and help you better decide which UI library to use in your project.

Here's the ranking of **the 7 most popular React Native UI toolkits and component libraries for 2021**. Enjoy!

#React Native Elements   
Let's start with the most popular one - React Native Elements is the most well-known UI kit in this ranking. The numbers don't lie - it has nearly **83 thousand downloads every week**. Also, it consists of almost 30 open source UI components made by developers for developers (so it's 100% built by the community).

React Native Elements is very easy to set up - all you need to do is install it via rpm or yarn. It can be built with either pure React Native projects or Expo projects. It works with React Native Vector Icons and can customize app theme using Theme Provider or Composition. Styling components can be done by their custom style props or containerStyle prop. So now you can see why it's so popular, right?
