Hi @arthurfowler - no, sadly not - this forum runs on the Wordpress CMS platform that is unsupported by Tapatalk (since 2017).

EDIT

However, the forum should run quite well on mobile - I've made a few posts from my phone, and the layout seems to work well. Any problems with this, let me know.
I've simply added a web link to the forum to my phone's homescreen (desktop), and it works as conveniently as an app, imo.
