BitcoinTalk do not have any official mobile app or mobile version of the forum however there was a user (long ago AFAICR) did something (wrote a script) that allows mobile friendly version. If I find the topic then I will update this post with the link.
Warning: The script may harm your account since (so far I know) that no one validated it. I will encourage to do you own due diligence.
I did try looking for "AFAICR" here in the forum but I couldn't find him.
Anyway, I have found a thread which I think may help to improve your browsing experience using mobile but it only works on android devices.
You can check it from here
