# Introduction

## OLO Mobile App

Based on [React Native](https://github.com/facebook/react-native) and [Expo](https://expo.io), we offer you OLO Full App; a well structured iOS and Android, having fully customizable pages along-with a rich collection of UI elements specifically for an ideal taxi app to help you quickly get started on your next project.

[Native Base](http://nativebase.io/) is a free and open source framework that enables developers to build high-quality mobile apps using [React Native](https://github.com/facebook/react-native) iOS and Android apps with a fusion of ES6. NativeBase builds a layer on top of [React Native](https://github.com/facebook/react-native) that provides you with basic set of components for mobile application development.

[Expo](https://expo.io/) is used to make react native applications. It provides a set of tools that simplify the development and testing of React Native app and arms you with the components of users interface and services that are usually available in third-party native React Native components. With Expo you can find all of them in Expo SDK.

OLO Full App is a bold and flexible [React Native](https://github.com/facebook/react-native) theme best suited for developing high-quality mobile apps that makes use of ready-made tools. The theme has several widget areas that allows you to extend your theme functionality with plugins. OLO is built using [Apollo GraphQL](https://www.apollographql.com) and is performance optimized which helps you to develop world-class application experiences on native platforms. This gives your app a consistent look and feel with the rest of the platform ecosystem, and keeps the quality bar high.

OLO is build using [Expo](https://expo.io/) it is powered with  [Expo SDK](https://docs.expo.io/versions/latest/sdk/overview/) to give you access to your device capabilities and the Expo services to handle the heavy lifting of building your app binary and uploading it to the store, all without you touching Xcode or Android Studio. With the "bare" workflow, we also speed up your development with the [Expo SDK](https://docs.expo.io/versions/latest/sdk/overview/) and React Native, and you have full control over your iOS and Android projects.
