Its a Tapatalk client. Its free rather than pay the 2.99 for tapatalk. Its called Convo(Tapatalk Client) So if you just want to try it out. You type: hearth.com/talk for the server name. Now I had a little problem getting it to accept that address but the 2nd or 3rd time it did and once I got my username and pass word in there its working fine now.
