I have never used an app more than once that didn’t appeal to my eyes or one that made me think about how to use it. Design is just too important, and good design is a sure way that your app stays on your customer’s phone.

Not only does design influence the behavior of your customer, but also drives perceptions and to an extent, helps you get to the app store’s featured list.

While it’s natural to consider design as the look and feel, it’s much more than that. Design means the form and function of your app and how your customers will navigate through it. Design means making sure you offer an overall fantastic user experience.

You should focus on three goals for a better-designed app (a creative vision highlighted by Google). First, enchant your customer. The look and feel is the first touch point for any customer that comes across your app store page or microsite. And when it’s one app among many in that category, it better stand out in terms of graphic design.

Second, simplify the life of your customer who’s going to use your app. It has to be so simple to use that your app doesn’t need to come with instructions. The interface has to be intuitive. The only way to test this is to create an interface and let your potential customers play with it. Study their behavior and improvise.

Finally, integrate a well-designed product with one that is personal and at the same time lets your customers experience new ways of doing things. To give you an example, a cluttered market filled with to-do list apps was confronted by Clear, a beautifully-designed app.
