DO NOT INSTALL

Do not install this app. It is free at first but they will bill you $6.98 EVERY 7 DAYS after. This is a scam. I did not know about this and had to pay over $60 by the time I realised it. And Apple refused to refund me for their horrible app. How did this app get approved by Apple? Apple needs to take responsibility for their apps marketplace. Will never download a paid app on the App Store again.
