Hm, in a way, no one really makes "one size fits all" apps, because if everyone did that, there'd be no way to stand out in a sea of hundreds of basically identical apps. So instead, these apps often follow the unix philosophy "do one thing and do it well". Unfortunately this means now there's a sea of hundreds of apps that do things in their own particular way, so as a user you also have to figure out not only which particular way you like best, but which ways you hate and can't use at all.
