invaluable Obergurg-Hochgurgl is a great resort. I went in a week some of the lifts were being closed due to high winds and checking their status via this app was very useful! Yes it is a webpage but all the huts provide free wifi and so it is easy to access.
It's not an app It's a web page and it requires internet connection at all times which means that it doesn't work for me when I'm at the resort. Messy and useless plus it has an iStupid name.
