If you are spending 12 or more hours per day on BHW and not selling a service or putting any of the concepts to use, you are doing something very, very wrong.
Regarding a BHW mobile app, there was a time long ago when the site used Tapatalk for mobile integration: https://www.blackhatworld.com/seo/new-mobile-app.577055/#post5697688.
However, Tapatalk started to act buggy, so Damien's team pulled it and moved it to Topify instead: https://www.blackhatworld.com/seo/topify-review.580447/
Users complained for hundreds of posts about lack of functionality, bugs, and that they prefer to just use their mobile browser. With the Xenforo update, BHW is very much mobile responsive. I have doubts that administration is going to give this the "third time's a charm" approach, and I don't blame them a bit.
The mobile site is fast, smooth, and works just as well as the desktop version. As
@kickthat,
@sturose,
@davids355 and others said, it works great, worst case add a shortcut for the bookmark to your home screen and you won't have to type in the URL any more if that is the issue.
