Flarum is great [1].

Looks good, works on mobile, continuously updated.

Try it out.

Edit: Oh wow, downvoted for posting a good recommendation?

I agreed (but I posted here to get some feedback). But I don't think it is continuously updated, as I noticed their update progress is quite slow through.
