I've been working in editorial for about 2 years and I was ager to get started with some UI/UX design.
First I followed this basic course for the design side on Sketch 3 here at Skillshare, from where I designed the screens: https://www.skillshare.com/classes/design/Intro-to-Mobile-App-Design-with-Sketch-3/2111159641/project-guide
And then I continued learning a bit more about the planning phases of this kind of projects and prototyping itself with this one.
Tough my app it's very simple, it helped me to better understand the proccess and things to keep in mind when designing and prototyping an app.
"Todo listo" means "All ready" in Spanish, so I thought it would be a fun word game to play with "todo lists" and getting "everything done" haha
