I've tried this with my website thinking it would be a quick way to expand my income, but it was not worth it. My SEO "juice" didn't translate much to my /de and /en pages. In my experience, you're more or less starting from scratch when you do this. And getting word of mouth and press coverage in a language that's not yours is not an easy thing. That said, what is your app about? I am a native French speaker and perhaps I could help you out.
