Not much more to say, I personally don't have any use for them. But maybe someday I will. I'd like to be able to turn them off, but I can't find any settings toggle for it like there is on the website.
Anyone know where the setting to turn them off is, or if there is a setting?
Edit: I figured it out, if you zoom in close to where the map changes, and hit the triple dot button, isolines option appears in the menu, they aren't present when zoomed out.
