4. Good design makes a product understandable.

It clarifies the product’s structure. Better still, it can make the product talk. At best, it is self-explanatory.

I believe that this principle is one of the most important factors to all the designers. People buy good designs because they love its simplicity and easy to use. Just like iPhones, there is not much explanation on how to use all the functions, users can easily figure out themselves. I think that’s the power of good design, people understand immediately when they start to use it, how these products make our life easier and convenient. The home button in previous versions of iPhone completely changed the design trends for cellphones. There was only one button but a lot of useful functions. now the home button removed from the newest iPhone with a bigger screen, the way to unlock phones is getting easier.

iOS App Design Principles

1.  After reading this article, I acknowledged that there are different parts designer need to focus on when designing the app. app design is not just personally throughout, is to think about it on user’s perceptions.

2. I think the most important principle is to minimize the effort required for user input.

It is important for people to follow the app with simple steps that well designed to help them efficiently use this app. It is easy for them making progress and are not being delayed as they move through the app.  Secondly, make it easy for users to make choices. The app should give the user a clear path to let them make choices. A complicated design would distract and confuse users.

3. I learned a lot from this article, designing an app is a long throughout process.  Designers have to think about all the situations on user’s perspectives. A successful app is always developing from different parts of  users’s test.
