I have checked the google playstore and i found bitcointalk application. I dont know if it is the official app of bitcointalk because the number of downloads are too low and the feedback are not good. Try at your risk as it might steal your information
It was already said here that this app is old and no longer support. It works terrible so nobody uses it. Any updates on this topic? What do you think about creating a campaign in which we would raise funds for creating such app? I understand that a new forum software is being developed and it's mobile friendly but we don't know when is it going to available for everyone.
