This is a very difficult question for me. Because it has a point of view and there are many kinds of sentences. Different structure, ideas, metaphor and concept. You must remember that in my opinion the text itself is appropriate and I have to answer my specific guidelines. The most important of many guides is how the author introduces or sets a better guide. For example, if the author is writing a cookbook, his first sentence should appeal to his preference.
Especially if the text is not artwork but as practical as most applications, let's consider what improves writing. You can tell something to explain this and you should not distract yourself. Usually, less is better. But they have to say the whole truth - so research is often the first. There is no gap. It sounds like a fantastic user interface. Let's consider the UX process. Many responsibilities such as requirements analysis, research, role and scenario development, functional concepts, information architecture, interaction design (creation of blueprints for UI to solve interactions or tasks), visual design, etc. are attributed to "UX" . I think these are best done by the team for complex, heavy-duty digital media such as applications at least.
Good sentences are very subjective. Some people say that they can write in the style they want and can use it to move the audience. For me, excellent writers can write not only in the way they want, but also in their own unique ways. Even if they know that there is no clear and acceptable perfection they must always achieve perfection. Logically, good writers need to pay attention to other types of compositions as well. Understanding other kinds of sentences is important to the success of your writing. Because different sentences are not related to the quality of the work. It is possible to become master of writing, but in other writings it is perfectly mediocre
If you want to be a good writer, the phrase "Practice makes you perfect" is established. Like other skills, lighting is a skill. Write things for myself, write blogs, and write other publications. Just writing it explodes. If you practice a lot, it will be easier after a while. It is wonderful to see the master in that field seeking inspiration. But it will be better if you come up with some good ideas of yourself. Please try out the style, tone, structure and theme of your writing. Please try out new words. Try everything inventing a new word. And please see what works and what is moving. This will help you to write better and help you to confident your thoughts.
