In Google, type in "ios guidelines" - this is for ios, "android guidelines" - this is for android, and so on, whatever interests you. And the first line in the search results will be the official guideline for the design and architecture of building applications on a particular platform, everything is usually painted there down to pixels ...
Also, look at the blogs, articles, sites that appear in the search results below, after processing your request - very often there are good articles, including eng + rus versions of eminent designers, where all these things are described. Well, or even come across templates and examples. There are a bunch of them.
The main thing is to comply with the guidelines, then the product will look unified, standard, and of high quality against the general background of this platform.
