I kind of disagree. I don't mind apps that bring their own visual styling and don't reuse OS components/styling, but I get _really_ annoyed by apps where gestures behave slightly differently. Things such as the exact tolerances required to activate the "fling" getsure, or to swipe from the edge, are really frustrating when they're not quite right. Beyond basic conventions, the minute details of how the user input/output responses work are really really important.

I hate when apps implement the swipe-back gesture for anywhere on the screen, rather than just the left edge.

It’s far too easy to be scrolling, accidentally go slightly too horizontal and end up popping the view and losing your place.

I hate it when swipe is inconsistent. Even using two Microsoft products (Todo and Outlook) on my iPhone, in Outlook you swipe right to delete a message from the list, in Todo you swipe left to delete a task from the list :-/ . Lucky "undo" is easy to find.
