The conversation options found on the mobile version are the same as on the web version: normal chat and spy mode. With the first you can talk to a random person about anything you want, always with the option to choose another random person if the first one bores you.
In spy mode, you send out a question that starts a conversation between two strangers and you can’t get involved. The moment one of the two disconnects, another conversation starts with two other random people. All you do is read their messages.
If you had a conversation with someone and you don’t want to lose it, you can save it on your mobile device or share it with your Facebook friends, who can read all of it once it's posted.
