Frequently asked questions 💬

What exactly is a “Design Manual” e-book?

This e-book and the practice files are all you need to learn mobile design and become a better designer. We wrote this e-book thinking about everyone lost in the learning process and missing a real actionable step-by-step guide on delivering a complete project.

I’m a complete beginner. Will this e-book help me?

Of course! This design e-book will teach you the basics of design for iOS and Android, but not only that. It will teach you the basic principles of design and show you all there is to know about mobile design. It’s made for beginners in mind!

How is it different from other e-books?

I’m showing you everything I know about mobile app design. It’s not another book written by a “designer” who’s not practicing what he preaches. I’ve designed over 170 products to date, made multiple-six figures from design alone, and been in this industry for over 6 years. I’m hiding no secrets here :)

Will this e-book help me make more money?

By following the theory and the guide, you will learn how to create commercial-ready projects that I have personally charged on average between £8000- £15000+. If you keep honing your skills after you read it, you’ll be able to attract much better clients that recognize good skills.

Can I use the practice files for my own portfolio?

Of course! The UI kit was made specifically for that reason. To help you get inspired and create development-ready designs to attract better clients. Just remember, don't copy the designs exactly as they are. Change colors and fonts, and play around with the images. Add your own little twist!
