Hello, in general internally I just use google chrome(most web browser support this functionality) and to see the mobile version I will inspect the page and just use the mobile button to view what it will look like in mobile. Sometimes to debug differences between mobile app and mobile browser we will use the mobile app. You can also set up that with https://docs.q2developer.com/guides/mobile_dev/index.html. We also will use the mobile app to develop mobile app specific functionality.
