Duh. I updated, and now have all the layers. I was on 1.03.
Hey! First, Windytv is now my favorite website on the internet!!! I am an atmospheric scientist and pilot who puts his surfboard, skies, and fishing gear in his plane, so you can see you've pretty much nailed my life's needs all in one!!!
Question: I have the Windyty app for Android, and not all the layers available in a desktop browser are available in the app. The main layer I used that is missing is 'Cloud Base'. That layer is critical for pilots.
App aside, your mobile version in the Firefox browser on my Android works great (with a few minor bugs), and has all the layers. Perhaps you should just scrap the App, and go with mobile browser development. If so, you should add a favicon to windytv.com, so when people save the website to their desktop, it's got your great logo!
Keep truckin'. I love this site!!!
