I’m tired of trying to find out which label is the best for me so now I just go by the label “designer”. That’s it, just designer. Some people like specializing in one area, though. Here is an article that explains the difference between UI, UX, interaction design, visual design and product design: http://www.fastcodesign.com/3032719/ui-ux-who-does-what-a-designers-guide-to-the-tech-industry. Overall, I think we attach too much importance to labels. Often, the boundaries between job roles are blurred.
