When talking about the number of screens in the mobile application design, it is often considered the flow where everything works correctly. Whereas the connection is disconnected, the user does not allow, the process is incomplete, or the desired content cannot be found. If these situations are not covered, interface decisions are made piece by piece during development.

Separate the next use with the first use

It is necessary to tell the first-timer how the product works. Passing the person who comes in every day from the same descriptions slows the work down. Think of empty account, sample data, first transaction, and returning user status separately. Plan the time of requesting permission according to the need of the feature.

Show connection and transaction statuses

It should be understood that a request has been sent, driven, completed, or failed. Evaluate scenarios with the developer, such as re-pressing the same button during payment or registration. The design should not deliver a definitive message of success in a situation where the server does not know what it is doing.

Type platform and accessibility decisions

The same visual approach can be used for iOS and Android; however, navigation, system permissions, and device behavior should be studied together. Large font-sized layout, touch targets, and screen reader order should also be included in the submission notes. Presentation prepared on a single phone scale is not enough.

Add a status list next to the list of screens at the beginning of the project. The design budget and calendar are clearer what to deliver when spoken through these two lists. In developer delivery, it is as important to explain the return and error behavior as the image of the screen.

Separate UI and UX coverage in delivery

UI handles the visual and interaction elements of the interface; UX handles the user's experience of completing the job. Beautiful screens are not proof of an understandable flow. The mobile app should be empty, loaded, error, permission rejection, and offline situations visible in scope. Evaluate design delivery with critical tasks and testing behaviors rather than reducing it to the number of screens.
