TeX support works fine in question and answer bodies, and comments can be rendered manually by tapping and selecting Render MathJax. See related question here.
However, the titles are not rendered which makes the browsing experience less than perfect. See screenshot below.
Are there any plans to implement MathJax support in titles?

EDIT: I was just informed about this declined request asking for the same functionality for the Android app. I guess I shouldn't hope too much then...
