User experience (UX)

Navigation is how you move around an app to find what you need. The main menu is the map of an app. A good main menu has only a few clear buttons, four or five, with names that say what they do, such as Home, Lessons, Homework and Help. A poor menu is long, hides choices inside other choices and uses names nobody understands. When a menu is too long, people give up. A good rule is that a user should reach any page in only a few steps. On paper you can plan a menu like a wireframe: a simple drawing in boxes that shows where the menu items go before any real work starts. The names must be short and in the same order on every page.
