World Lens is able to do this real-time on live video. Not for Polish, they're not. They also sadly don't support my beaten-up old ZTE Blade. Google translate has them beaten for both. Edit: regarding the "everything is free" philosophy, I would glady pay for Word Lens. If it ran on my phone. And supported Polish. Neither of which I see as being terribly likely in the future. goes on rant about how much I'd pay for a Polish lexicon in a format I can run some fun statistics against
