@hund@linuxrocks.online on android I have been using Revolution. I got one server working but it took many many tries. I don't know why it wouldn't work. Perhaps it has something to do with the FreeNode network. It finally let me connect, but then I lost the connection and it wouldn't connect again. I tried MEMO encryption and that's when it simply stopped connecting.
On Linux I use WeeChat and it works perfectly. Encrypted or not. So my problem might just be with the clients.
