Currently it is necessary to open the menu on the right and to scroll till the end of the menu to switch model.
This is a bit tedious when one wants to check what different model predicts.

I would suggest to let the user move the model selection panel on top of the menu.
As an alternative, you could add a custom shortcuts in the main page of the app (near the house, search, pin and heart icons) to let the user access directly the model selection menu.

I would be great to implement the zoom as in google maps and other map applications, where double pressing plus swiping allows to zoom in and out.

Using two fingers to zoom out is not comfortable.
