To remove their ads, requires monthly fee

I haven’t checked to see if it actually produces an app or not. But, FWIW, here are the financial terms — which you have to install the app to find out — are as follows:

$9.95 per month.

1 star rating for not just saying this on wordpress.org, or on the non-registered-yet-installed plugin, or on their own website. Why would anyone honest not just state the amount up front?

Here are the applicable terms of use:

3. Payments and Refund Terms

The basic service is free with ads by the Company. In addition, the Company offers paid upgrades for PRO features. By selecting the PRO level you agree to pay the Company the monthly subscription fees indicated for that service. Payments will be charged upon activation of charged services.

A valid credit card or a Paypal Account is required.

The paid use of the Service is non-refundable. In order to treat everyone equally, no exceptions will be made.

All fees are exclusive of all taxes, levies, or duties imposed by taxing authorities, and you shall be responsible for payment of all such taxes, levies, or duties in your location.

The Company will do its best to provide tools to help you increase the probability that your Apps will be approved by and accepted in a third party app store. Note that the Company does not and cannot guarantee approval or acceptance into an app store.

If an app store denies your application you may cancel your account; however, there are no refunds of payment for the Service under any circumstances…

Also, the terms say they can cancel your app at any time for any reason.

Company appears to be based in Italy, so unlikely to be bound by U.S. laws.

Or by any sense of decency which would prevent them from using the Comic Sans font in their demo.
