First of all, do not pay attention to the same appearance. iOS and Android are completely different OSs. In Titanium, you do not have many of the controls available for iOS.
Let the appearance and appearance be different for Android, do not do it iPhonish.

Although their documents are not supported properly. I would suggest you use cool graphics that can improve the look of the application.
I created a button and a label and a text box. It looks good on the iPhone, but is scattered in Android.
It should not be, write your code. Appearance may vary, but it should not be scattered.
