Course Description
Welcome to The Complete Guide to Designing a Mobile App!
The number of app downloads worldwide in 2017 was 178.1 billion.
The average US user spends 5 hours per day on their mobile phone, primarily browsing apps and looking at websites.
In 2020 mobile apps are projected to generate 188.9 billion U.S. dollars($) in revenue via app stores and in-app advertising.
There are millions of apps out there to download, and (literally!) billions of dollars to be made by app creators. How do you make your app to stand out from the crowd? How do you get users for your app, and keep them?
One answer: GOOD APP DESIGN!
Why Learn App Design?
Many fantastic apps never find a big audience, and one key reason for that is that they're poorly designed.
A good design will make your app stand out from the crowd, and keep your users coming back for more!
There's a difference between building an app and designing it; it's the difference between an app that works perfectly, looks fantastic, and does exactly what it promises... and one that doesn't.
The more design work you put in to your app, the more successful your app will be.
Why Choose THIS Course?
With the same focus on practical learning that Rob Percival brings to his courses, in this course you'll get a brief overview of design principles before getting into the how to and learning by doing, with regular exercises and challenges to test and cement your learning. The first half of the course focuses on:
Design basics - learn simple (but devastatingly effective) design principles. Understand the differences between iOS and Android design systems, and what that means for your app.
Polishing your idea - tailor your app to your users, and stand out from the competition! Learn how to sketch out and wireframe an app idea, and see the difference this makes!
Information architecture - the backbone of any good app. The structure of your design is so important - learn the guiding principles of app and information architecture here!
Style - colour, font, icons, typography - everything you need to know!
Components & patterns - Help users navigate your app. Create forms, fields, notifications, animations and more!
The user experience - make your app simple and intuitive and your users will love you. Learn how here.

Really enjoyed this course. It made me look at things from an entirely new perspective.

Overall Good course, good I can see she know the what she is talking about. Classes well prepared, good speaking and words flow
By Bülent Başyurt on 4/4/2020
Instructor made the course by reading from slides and making designs not from the scratch but using ready design blocks. Didn't meet my expectations and had to buy another course.
By Patrick Cook on 1/8/2019
Overall, a nice course. Well planned and executed. Some of the content was read from the screen (instead of discussed), but the discussions about Sketch and InVision very helpful to this Adobe man. Would be a great help for a beginner.
By Robert Suffern on 12/12/2018
Very good overview of a lot of topics. If you are just getting into app design it is a very good overview of the design process and especially a lot of tools that you can use to get you productive quickly. I especially appreciated the in-depth overview of Sketch. I had no idea that there was a tool out there that had such an amazing amount of plug-ins and templates available. I think I now have the tools to successfully design my app idea. There are a lot of topics here and they go over them quickly.

This course covers all the basics, but also delivers a lot of content that people who've designed mobile apps will find useful. It's presented in an easy to follow manner and progresses in a way that makes sense.
By Juan Ugarte on 11/6/2018
Impossible to follow the course because of the speed and the instructor did not go deep in the topics. She jumps extremely fast from one concept to other. Impossible to hear and read at this speed and to retain the concepts. Using speed of 0.75 also is not adequate, it's very slow. Unfortunatelly a good idea not well performed.
By Janine on 10/24/2018
This course broke down what design really is in ways I hadn’t heard before. It was so helpful and very much geared to the beginner but also not patronizing. I loved it!
By Ryan Phillippi on 10/9/2018
The instructor is very thorough and I also like how she gives a history and background of the content and how it has evolved.
By Edward Anetsky on 9/17/2018
The Complete Guide to Designing a Mobile App is a great course. The combination of introductory lectures with the hands-on training makes it easy for even a beginner to understand the concepts of app design and be able to dive right in. I especially enjoyed doing the 3 projects in the course. Being able to do the work myself helped my understanding. The “solutions” to the exercises clearly explain every step of what is needed to be done. As well as teaching me app design, this course is also a great introduction to the design tool Sketch. It’s great that I will have access to this course moving forward, as I’m sure I will refer back to it many times in the future. I highly recommend this course!
