Deploying to a Device Improve this doc
Testing your app in the browser with ionic serve or with an emulator is fast, easy and convenient when your app is in development, but eventually you’re going to have to test on a device. Not only is it the only way to accurately test how your app will behave and perform, many Ionic Native plugins will only work when they are run on actual hardware.
