Definitely not perfect
Even if it was free, it has a lot of bugs that needs to be fixed like, for example if I would have to immediately exit out a game or, for some odd reason, it runs out of battery and shuts down it automatically skips the part and leaves it out or skips it But for a couple of bucks ,it should have all the cards working as they should spelling and grammar, as well as words should be correct and also not mixed up and did have some place testing to see if it functions all the way properly
