It's easy - integrate the Hipmob library into your website or iPhone or Android app, and login to your preferred chat client. Hipmob works with any Jabber or XMPP enabled IM client. We currently have instructions for Adium, iChat, Pidgin, Instantbird, and imo as clients. Users will show up in the buddy list of your chat client, & when they want to talk to you a chat window will open up.
We also have a chat client built right into your dashboard, so you dont need to download/install any special software or sign up for anything else to use Hipmob. You can use it from here, or you can integrate with your Gmail, Hipchat, or Campfire to get notifications when users need help!
