The forecast page is the landing page. I was just confirming that you were for sure referring to that as the display with the blue background is the card display and used to be the landing page. Here is a screen shot of the forecast page and the circled Tempest icon is the quick way to get to the card page.
The card view, shown below, is called such since you can move the cards around using the app by tap&holding on one for a moment then you can change the order.
Under Settings, Stations, station name, Advanced you can hide the forecast card and/or the battery card. At least on Android, if you don’t close the app and it is on the card view, when you go back to the app it will show the card view. There is a request to have the default page be user selectable.
