In fact, there are several basic principles for creating a UX design that applies to all mainstream applications:

Provide unambiguous choices. You need to avoid creating complex interfaces that may puzzle users; Choose proven methods of presenting the information. When developing products for the most extensive target audience, you should not be too creative. Instead, it is better to give preference to proven interface elements. On the other hand, it’s still worth analyzing and taking into account current trends – you don’t need the interface to become outdated before the project’s release, do you?

Use more graphics and less text. Users do not like to read large arrays of text; do not force them to do it;

Limit the number of functional elements. In one functional block, there cannot be more than 5-7 elements, otherwise, the user will not be able to keep information in their short-term memory;

Submit information in groups. It is desirable to break information on the screen into logical blocks (groups), so the user can percept it easier;

Do not hide the really important elements. All the important interface elements should be visible and appropriately highlighted;

Follow the three clicks principle. No more than 3 clicks should be made to move from one section to any other. The same rule applies to the start screen: any important information should be available in no more than 3 clicks;

Do not disperse similar control elements. Settings and controls should not be hidden in separate sections but managed from one place if it is appropriate. Read more: https://www.eleken.co/blog-posts/banking-app-design
