DON'T DO IT!! RIP OFF!! The "stars" you have to buy or earn, have a tendency to just disappear this has happened to me three times already. Also you can purchase "stars" but you don't receive them. And you can use one of your hints one being the definition and it will say cannot find definition at this time but still charge you and take away "stars". I'm going to uninstall and suggest you completely skip it. save yourself the hassle it's so not worth it.
