Installing an app on an iOS device requires a Mac, an Apple ID, and a USB cable.
Connect your device to your Mac via USB, then open Xcode. In the project navigator, choose your device from the Product > Destination toolbar menu. Xcode will then register your device for development.
If you run into any issues, please take a look at Apple's Launching Your App on a Device docs.

Running an Android app on a device requires a Mac or PC and a USB cable.
Most Android devices can only install and run apps downloaded from Google Play, by default. You will need to enable USB Debugging on your device in order to install your app during development.
To enable USB debugging on your device, you will first need to enable the "Developer options" menu by going to Settings → About phone and then tapping the Build number row at the bottom seven times. You can then go back to Settings → Developer options to enable "USB debugging".
Let's now set up an Android device to run our React Native projects. Go ahead and plug in your device via USB to your development machine.
