I know this because several different reviews have the same title, and there is no way that a scam app is 5 stars. This app has already been reported, and I hope it gets taken down soon. Take your safety first, and steer clear of this app. **Developer response:** Dear hulkattack11,We sincerely apologize for the distressing experience you've encountered.
