User interaction

 Building mobile apps is not much different from building websites in terms of processes - both are digital products.


The main difference lies in the user's interaction with the product. We sit or stand at the computer, but with the phone we can find ourselves in any situation: on a walk, playing sports, in a store, car, and so on. The size of the devices and the period of contact also differ.


Smartphones are smaller than PCs and laptops, and app usage sessions are short but frequent, all of which need to be taken into account. The application screen should contain a minimum of information - only useful information. The user must quickly access the content. Take, for example, Google Mail. If we go to the browser version from a computer, we will see a lot of additional information. On the phone, we see only letters, the rest is hidden and shown on demand (pressing) - convenient.


Largely due to the desire to quickly and conveniently receive information, mobile applications have appeared.


After all, to go to the site, you need to enter its address in the browser line, and the application can be opened and immediately used.

Goals and objectives of application design development

The designer must understand what tasks the business has and for whom the application is intended. An application is a business tool with its own goals and objectives. For example, consider a mobile application of a bank.

Business goals:

  • reduce customer service costs in branches and increase average revenue per customer.

User goal:

  • control your expenses.

Application tasks:

  • create a remote customer support channel and increase sales of banking products.

When developing an application, business requirements, user tasks and technology opportunities are always taken into account. You can make a great design, but it will not solve the company's problems or the developers will not be able to implement it. For example, it happens that a business puts forward hypotheses, does not test them at the research stage and immediately sends them to development. It turns out functionality that no one needs, while time and money are wasted. It happens that resources are wasted not only on useless features, but also on the application.
