What criteria determine a high-quality user experience when using mobile applications?

A high-quality user experience (UX) in mobile applications is defined by the following criteria:

• Intuitive interface: the user should easily understand how to interact with the app without a long learning curve.
• Responsiveness: the app should respond quickly to user actions, minimizing delays.
• Stability: absence of crashes and errors that can interrupt operation.
• Adaptability: correct display and operation on different devices and screens.
• Accessibility: support for various user groups, including people with disabilities.
• Minimalism and focus on the main: do not overload the interface with unnecessary elements so that the user can quickly achieve their goals.
• Feedback: the app should inform the user about the results of their actions (e.g., animations, notifications).

Example: if a download button is prominently placed and quickly initiates the process when pressed, the user has a positive experience.
