Built in React Native using Expo CLI
Assuming that you have Node 12 LTS or greater installed, you can use npm to install the Expo CLI command line utility:
npm install
npm install -g expo-cli
Run the Metro Bundler on localhost
expo start
You'll be given a QR code in your terminal and/or browser. Scan it with Expo Go (Android) or the Camera app (iOS) to see the app in your phone.
