Android app based on an iphone version

We've an iPhone app already and we need an Android version of it. The Android version must have the same features. It's has to be overall similar in design, but we are open to suggestions of improvements. You must see the application's screens and functionalities on its micro site: [login to view URL] It's a simple app that retrieves the content from our website ([login to view URL]) that runs on Wordpress. There is also a plugin on Wordpress that retrieve the content from database and send it to the iphone app using Json. Note: We can send you the source code made on objective c (xcode project) if you think it can help. Important: It's a bilingual interface/content: English and Brazilian Portuguese. (We can help with the translation) We're are open to develop using other tools like Appcelerator Titanium, Sencha Touch etc. The only thing that concerns us it's the overall app performance after compilation. This can be an issue. Feel free to ask any questions! Cheers from Brazil!
