As long as an app is easy to use, people prefer a single look. No one cares about "looking like the OS", except maybe 0.1% of users.
No, people are used to an UI language, which in the case of iOS is quite consistent across applications. You expect certain things to work (e.g. flicking in from the left edge means "go back"). There are platform-specific patterns and I'd rather have the app behave accordingly rather than being consistent with other OS' version. The real 0.1% here are probably the users of your app with active devices in both Android and iOS!
still have many domains on there, all with gmail
