I personally feel that borrowing from the native interface will improve the user's experience, especially in terms of navigation. It seems to me that since hybrid apps are distributed in the same way native apps are, this behaviour is what the user will expect, but I've also come across some articles recently that claim trying to replicate the native UI is a bad idea and will risk angering the users if some part is slower or does not behave in the right way.
So, should hybrid apps be based on the native UI of the device or is it encouraged to go for a different, possible more generic, mobile website-like interface?
