As an exercise to get acquainted with Sketch, I’ll try to replicate a few screens from Amazon’s Alexa app. Ironhack prework exercise 2. What I’d like you to know before you see my work of art: This is my very first time using Sketch or any other UX/UI design tool. I could not find a way to replicate the app’s typography. I don’t really know how to replicate some of the icons either. I’m a little embarrassed, a little proud, and very excited about the future.
