I've put together a little web app because I think the standard apps miss the mark a bit, it will calculate overlaps, clashes and if you share with your friends it wil tell you which bands you're both seeing at the same time.
http://gavinbenda.com.au/sw/ <--- designed to work on an iPhone/Android.
It's just a little side project so nothing official.
Let me know any feedback - apologies it's only Adelaide unless someone wants to send a text list of their state and start/end times!
Countdown timer will start this afternoon, don't forget if you want to share your list with a friend, you can just enter their email or username into 'sharing settings'. Handy way to work out which stages you should head to if there's any overlaps or you don't want to lose a group.
