On windy.com, there is a model selection control at bottom right without entering any menus.
On iPadOS and iOS, we have to open the hamburger menu and scroll all the way to the bottom to change model.
On iPad there should be enough space to have similar controls to web. Possibly also on iOS (phone) size screens.
Secondly… we should have a way to default to a different model. I’m aware of the setting that lets us set the startup layer, it would be useful to be able to set the startup model.
