Bing Translator, Android equivalent?

[katamari201]

I just found out that Bing Translator has an offline mode. It also has a cool overlay feature to OCR and translate from pictures. I was wondering if there was an equivalent app on Android that's as easy to use. I'm thinking of getting cheap windows phones so they can use this feature as they have no data plans and it has to be simple and easy, but don't want to take android out of the running. Google Translate seems pretty limited beyond just having a lot of language options, from when I messed around with it.
