Good for learning and studying words

Im using this app along with a few other. This app is great for learning new words and testing yourself. It does not show you grammar, culture aspects, etc. I would give it 5 stars if it allow you to choose what words to study and remove the one youve learned. It also would be nice to have a counter showing how many words are left to review.
