About Expo

Expo just makes you productive out of the box as soon as possible. With React Native alone, there's all this overhead to configure an Xcode or Android project, or to get it somewhere where you can actually share with your teammates or other stakeholders.

Expo apps are React Native apps which contain the Expo SDK. The SDK is a native-and-JS library which provides access to the device’s system functionality (things like the camera, contacts, local storage, and other hardware). That means you don’t need to use Xcode or Android Studio, or write any native code.

Expo also provides services which typically are a pain to manage but are required by almost every app. Most popular among these: Expo can manage your Assets for you, it can take care of Push Notifications for you, and it can build native binaries which are ready to deploy to the app store.

Our office is in Palo Alto with a few partners in Seattle and Vancouver. If you're interested about working with us, learn more here.
