I have a few apps built for macos which I sell on app store. I really like to keep app sizes small. Like if I would try to use a library and see that the app size blow up from 5MB to 50MB, I would not use it. So basically I don’t use any libraries and keep my apps in sizes of 3-5MB.

At the same time I saw some comments, reviews about my apps, that they are probably would not be good just because the app sizes are too small.
