Feature for apps like Duolingo to help you write messages in the target language.

So there was an app for learning Spanish called Busuu, it had a feature called "Practice" where you can write a 100 word message in the target language (in my case Spanish) and you can give words you are unsure of the translation of in English or your native language and someone will correct it in the target language. In return you correct others in Spanish. <br><br>I think it would be great if Duolingo and maybe other apps had that as well.<br><br>The interface would be easy to navigate: at the top, you give the message, below is words you can translate with their translation, and at the bottom the language you are correcting. If you know a word's translation you don't go to the top, but just click the word and you're done. You can use Duolingo's database for the translations.
