 User Interface plays important role in deciding the
success of the app.

are placing buttons smaller in size, placing big or
small images in different places and selecting
wrong color patterns for views.
 Clarity of interface is much required for any app.

 Expert vs novice users
 App should be efficient for expert user and it should
provide information to novice users

 Flow direction plays important role in designing mobile app.
 For example, for a right-handed person, circular flows with a
pivot point at the bottom right of the screen are much easier
than linear flows

8. IMPORTANT CONSIDERATION FOR USER INTERFACE
 How much is too much
 The button should be limited, if we place more no of
button then it will be tough even for expert user
