I keep 3 Windy widgets on my home screen, but I still have to use another app to get a clear view of the temperature and precipitation trends. No matter how hard I try to read the little cloud and rain droplet icons, my mind doesn't lock in the same way it does with a graph.
The winds are graphed by colors so you can instantly notice the subtle changes and trends, but you don't get the same precision by looking at icons that you would with a graph. I realize that the app is called Windy for a reason, but I don't see why it couldn't highlight other data as well in optional widgets. I would certainly love to only keep a single weather app. The information is in there already, just not in an easy accessible way.
Thanks as always for the great app, and your consideration.
