Is the aivi app a scam?

Hi, recently I read an app called aivi here on Applevis. I signed up for the beta and tested it, however it is a complete mess. Now, since signing up, I get tons of spam emails and someone is sending transfer.it links under my email adress. And since I can't find anything about aivi and everything about them looks strange I'm wondering if I just fell for a scam. So my question, anyone using this?
