I'm writing an web app that gives the user a word to translate, and he accumulates points by doing it right. Then he moves to more difficult words. Is there a similar web app out there?
I know many sites like busuu.com have lessons exercises that are similar. But they differ in 2 ways:
- It requires to watch a lesson and,
- It gives possibles answers to choose from.
I looking for an app that doesn't show the answer, unless the user requests it.
