HexChat

Been using this for years, love it. Happy its on the store, makes it very quick to get bck to where I was. Consider syncing settings with cloud storage like a lot of store apps do. Would really be awesome if I didn't have to reconfigure my servers and bnc every time I reinstalled....

Found this years ago as an easy way to get into IRC. Nice interface, pretty stable, I don't really have anything negative to say.

To use on screen keyboard, must exit tablet mode, manually size window, then type.
