Now that our Hello World app is created, let’s take it for a spin!

Install the Expo Go App

You’ll be testing the app on your personal mobile device. In order to do that though, you’ll need to install another app called Expo Go.

The Expo Go app will sync up with the Expo command-line tools that we used to create our app in the last exercise.

• Expo Go for Android
• Expo Go for iOS

Ready, Set, Go!

Once you have the Expo Go app installed, let’s run the React Native project. From inside the Visual Studio Code terminal, type the following:

• npm start - Starts the app

Now open up the Expo Go app you just installed, and scan the QR code which should have popped up in the terminal.

It might take a second or two to load up, but your new React Native project should now be running on your device!
