User reviews

Disappointed

Only gives a little bit of information, very little help and everything is just a general overview, would not recommend

App doesn’t work

App doesn’t go past the welcome screen.

No Trial Offer

Requires you to pay for premium version to see if it even works. Yes you can subscribe for a month and then cancel but most people won’t waste five dollars on something they can’t even see if the basics work.

Response from developer

Pay Before Use

Developer expects $5 or $20 payment without allowing use of the app to see how it works. Useless.

Response from developer
