It is a fact that most accesses to websites and systems today come from mobile users – cell phones. Unlike the desktop, with large resolutions and lots of pixels of space, small screens are a limitation; the touch screen, as a new form of input and control, makes new UX and UI recommendations emerge for this format.
Here are some mobile usability tips that make all the difference for mobile app UI design and experience for the mobile visitor, taking the opportunity to remember global tips that cannot be left out.
Too much information brings disorder
Every button, image, text, form field and icon added makes screens more complicated. Minimize the user’s mental load by making objects, actions and options clearer and more visible.
Nobody wants to do the same job twice
Look at all the flows looking for the ones that are the most work. The user should not need to remember information that he filled in during different and previous steps of the flow, such as having to re-enter some data that was already informed before, or that is the pattern, or having to make decisions that he has already made before .
A little bit at a time
Find ways to break a main task into subtasks. Large and long tasks generate more complex interfaces. A flow should be, whenever possible, divided into linear steps where the sense of progress is visible and the option to go back is always within reach.
Screens and conventional terms
Design screens thinking about how familiar they will be, which everyone expects to find, to your user base. In apps that contain feeds, these screens would be “Home”, “My Feed” and “Search Results” – always use your industry standards.
Today there is also a lot of talk about microcopying, writing custom text for buttons, warning texts and error messages. It is wonderful for branding within the product and humanizing interfaces, but when it deviates from the main idea.
