If you mean the visual "look", 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. If you mean UX in the sense of "how it works", learn about user testing (just watch people use your app) -- that's the biggest bang for the buck, IMO. Krug's "Don't make me think" is a good start. If you mean UX in the broad sense of "your user's life is improved by using your app" -- this is more of a product design thing -- my go-to recommendation is learning about Jobs-to-be-Done theory. Start here: http://jobstobedone.org/radio/the-mattress-interview-part-one/ http://jobstobedone.org/radio/the-mattress-interview-part-on... and then look around that site.
