What, exactly, do you mean by "options"? There is certainly a career to be had in mobile development. It's probably good not to focus exclusively on one platform, though. Cross-platform frameworks like ReactNative, Flutter, NativeScript-Vue etc. are gaining a lot of ground.

That list contains just job titles, some of which seem dodgy or duplicate. For example, what's the difference between "mobile developer" and "mobile app developer"? Mobile development is career-wise similar to web development or other kinds of development - there's a progression from junior level to senior level, an architect role, team lead, etc.
