I agree with everyone else. I too downloaded this "free" app to see if I would like the layout of this app before purchasing the "full" version. The "free" app should be an entisement for people to want the "full" version. The few words that you give are off the wall & the quiz is all screwed up. It gives signs BUT the right word is NOT shown. At first I thought I was wrong then I realized that one answer is not showing. It is somehow covered up & no way to get to it, so the quiz tells you you are wrong. If you want people to buy the "full" version you need to give them a few useful basic words & fix the quiz in this "free" version. I will not buy the "full" version if the quiz is not working properly in the "free" version. It makes me think that the $4.99 "full" version will be screwed up too.
