If you mean the visual &quot;look&quot;, I would just buy a template or engage a designer (even 99 designs). This is for graphic design in the sense of layout, color, fonts, etc.<p>If you mean UX in the sense of &quot;how it works&quot;, learn about user testing (just watch people use your app) -- that&#x27;s the biggest bang for the buck, IMO. Krug&#x27;s &quot;Don&#x27;t make me think&quot; is a good start.<p>If you mean UX in the broad sense of &quot;your user&#x27;s life is improved by using your app&quot; -- this is more of a product design thing -- my go-to recommendation is learning about Jobs-to-be-Done theory.
