I've been here about a year. I never had to download anything
to use swc IRC...I just open Live Chat in a window (phone or PC) and use it. [[ OCC: I never use 'chat' outside of SWC except
FB Messenger ]]
Is there an app I should download to make using swc IRC 'better' or 'easier' to use? Or does it matter?
If you're on Windows and want a chat client, the default suggestion is to use mIRC, which has pretty much been the leader in the field for over a decade. There are plenty of other free clients too, like X-Chat, a pretty exhaustive listing of which can be found on Wikipedia.
The real problem is there's no way to make one work properly for the iPhone :p The way iPhone background services work (as far as I know when I was looking into doing iPhone development), they're only given 10 minutes of "background time". So, once an app goes into the background, it has a maximum of 10 minutes before the OS kills its process.
I personally use andchat. I always had issues with androirc and I felt its UI was a bit strange. I like the more traditional looking IRC client, though, which andchat fit the definition of when I was comparing the 2 years back.
