The way the information is displayed to the user can drastically change the ease with which it is understood. When we talk about mobiles, where space is very limited, limiting the number of options and providing navigation adapted to small spaces can help our user have a more satisfactory experience.

As you probably know, the human working memory is not limitless, and it is commonly thought to be limited to remembering a maximum of seven elements (https://en.wikipedia.org/wiki/The_Magical_Number_Seven,_Plus_or_Minus_Two). Some authors such as Nelson Cowan suggested that the number of elements an adult can remember while performing a task is even lower, and gives the number of reference as four (https://en.wikipedia.org/wiki/Working_memory). This means that your users will understand the information you give them better if you block it into groups according to their limitations.

Once we create a new structure, we can evaluate the efficiency of this new structure versus the last version. With small improvements, we will be able to increase user engagement. Another way to learn about how the user understands the organization of our app or web is by testing a competitor's product. This is one of the cheapest ways to create a quick prototype. Evaluate as many versions as you can; in each review, you will find new ideas to organize and show the content of your application or web app better.
