A language learning app that generates sentences of a story in the new language with missing words and then gives you two options to fill it in, one right and one that doesn't work. When you fill it in wrong it shows up red and then you have to select the right one. When you fill it in right, the sentence completes, and then the next sentence of the story is generated below the first with a new missing word. This continues until the story is complete. The app is available for learning Spanish, French, Italian, English, and German
