Unless a unique UI is a selling point of your app is that really desirable? After all, Android and iOS user interfaces have (somewhat) different conventions.
They are getting closer and closer so we're at a somewhere in the middle design where it doesn't really feel out of place on either platform. In some areas you can admittedly tell we leaned heavily towards iOS (i.e. pickers). Three factors led us this direction.
a) We're a small company, we can't make having separate android and ios teams feasible. Writing and maintaining a single code base and separating out ui/platform concerns from that was ideal.
b) User training is much simpler if the app walks and talks exactly the same way when you have a large number of not-necessarily-technical users. Especially when some of those users may have android phones and iOS tablets and hop between the two.
c) Similar to b, customer support is much simpler when things work the same way and look the same way, again, especially for not-necessarily-technical users. Sending screenshots, directing over the phone or email, etc, all get much much simpler.
