This app cannot do what it claims & it’s not supported by the creator
I’ve tried to reach the creator at the support website (Twitter) but the site literally says that the creator cannot be messaged; the last post for this user was on October 30, 2018.
I’ve tried to contact Apple about the app (using the link on the app’s page) but it’s not willing to allow contact if you haven’t purchased the app.
So, now I’m saying, this app is dead on arrival and isn’t worth your time.
