Easily the best IRC on iOS.
Ive tried so many different IRC apps but none of them are too good. This one gives you access to IRC without any hassle. It supports SASL NickServ and ZNC passwords right in the settings. There are great themes for the IRC area. Swipe to delete channels and other stuff. It can do image upload easily through imm.io. It integrates with iOS notification centre well so you can get messages on your lock screen. The implementation is better than most desktop clients.
This is an outstanding IRC app. Hats off to the creator.
