I haven't been on IRC for quite a while so I was looking for a modern client that friends of mine used. A few of them independently recommended to give IRCCloud a try and so I did.
Web based client for the desktop, native clients for iOS and Android. The best thing: all of the clients you are using are kept in sync. A bit like if you would host your own client on a server that stays connected for you and that you can SSH into but with way better user experience.
findable.
