Here is a look at the 10 items that the guidelines outline as items that designers need to consider when trying to meet the five key principles associated with usability:
Visual design. Apps should promote legibility, clarity of content, and user engagement without unnecessary distraction.
Readability. The text should be readable, understandable, and adjustable, without altering the screen layout in a way that would confuse users or make it hard to use.
App navigation. Users should be able to go between screens quickly and easily to complete tasks.
Onboarding. Launching, registering, entering personal information, and preparing an app for first-time use should be an intuitive process.
Feedback. The app should give users efficient and informative feedback based on their actions within the app.
Notifications, alerts, and alarms. These general reminders, nonurgent and urgent indicators need to consider the safety and usability to inform users when attention is required.
Resources and troubleshooting. Apps must incorporate features to guide the user when help is needed.
Historical data. Information should be easy for the users to access, read and understand.
Accessibility. Apps should be able to accommodate a wide variety of users, including those with visual, auditory, or cognitive impairment, as well as those with learning disabilities and motor impairment.
Ongoing app evaluation. Apps should undergo robust, iterative evaluations that follow a user-centered design process during the entire development lifecycle.
