This app is really good for improving your singing. But, the only problem is this app probably allows only you from your family to make an account, because it bans all other accounts and it's no fun when the account is banned, because they can't sing in party rooms, they can't give gifts to appreciate. Actually, my id in this app is okay but when I asked my mother to join as well, the starmaker banned her id, it also banned one of my friend's id which is not even new (having 48 level)
