There are times when the Mobile Apps being tested do not need to be connected to your development machine. Hybrid Apps mostly run JavaScript code, so the debugging is done mostly on the JS console. The remote debugging can be done using two ways, one using Chrome's remote web inspector tool and the other using a free tool called jsconsole.
Chrome enables a special remote debugging protocol for iOS and Android devices. It helps you see the logs remotely for your Ionic App running in a browser or as an app on your devices. In Android, the remote debugging is enabled for Chrome and also WebViews in apps. In iOS, remote debugging is enabled for your Ionic App running in Safari.
