Hi,
There is no difference of Sounding tool between website and mobile app.
Or, are you talking about Soundings in Windy plugin ? Plugins are only available on website.

@martymack Hi, you can set elevation in the app too, there is elevation bar in the side menu.

It seems to me that you can save your favorite page of Windy as a bookmark in your browser. It opens the page with the location, layer and diagram you want. Only possible on website.
In Airgram colors are used for temperatures at each levels which is useful too.
