How to design easy-to-use iPhone apps that stand out

9 Principles of iPhone App Usability book cover

Designing a successful iPhone app is hard

With over 1.5 million of them on the App Store it’s a competitive space so people expect high quality. And whilst people are spending ever more time on their phones, they are using 80% of that time in just three apps. It has become even more important that apps are highly intuitive and easy to use to make the most of that short period of attention.

Do you know the usability rules you should follow when designing interfaces? And have you thought about how these apply to mobile?

Apple’s Human Interface Guidelines explain their best practices but this can create very similar looking apps. You don’t want an iPhone app that looks just like the Apple template. You want something that looks unique too.

Follow behavioural truths

Starting with a true understanding of human behaviour will help you design iPhone apps that are easy to use. You need to get to grips with the concepts that create highly satisfying experiences.

This book takes long-established guidelines by usability experts and fully updates them for the world of modern iPhone apps.

Learn from the success stories

This book demonstrates these usability principles through over 30 different iPhone app examples—proving that there are many different ways you can solve these requirements.

Ever find yourself copying an app for inspiration, without really knowing what makes it tick? This will give you a much bigger pool of inspiration with apps from a variety of sectors.

Don’t design an app that launches to a wave of negative reviews. Make sure it's usable so your users can get their tasks done with ease.

FAQs

How does payment work?

It's handled by Gumroad in their secure pop-up window. There's a bunch of information about buying safely with them on their site (I won't ever have your payment details). Also as they're US-based, payments are taken in dollars.

Why is VAT added on top?

VAT is an extra cost for most European based buyers and applies to all online products thanks to a recent EU law. Gumroad automatically handle it and add it on top, so I've adjusted my prices down to allow for it. If you're making a business purchase you can get an invoice from them to claim it back. If you're outside the EU, no need to worry.

What if I don’t like it?

If you get to the end and you haven’t learned anything, I don’t want you to feel ripped off. Just send me an email explaining why (to help me improve), along with your purchase receipt within 30 days of buying and I’ll issue a refund.

If I just buy the book, can I get the videos later?

Sure, if you fancy upgrading and getting the videos as well just email me and I’ll give you a discount code to buy that version.

Have you written something like this before?

Yes, this book is based on a series of blog posts I wrote in 2015. I took these blogs as a starting point and fully updated the content (rewriting the majority of the text) and added more for each one. But if you want to just read the initial versions for free, you can do so here.

I have a question you've not answered here

If there's something I've overlooked, just send me an email with you question and I'll try to get back to you as quickly as possible.
