BEWARE
I took advantage of the discount offered for the upgrade. However, after they took the money for the upgrade, they advised that the functions were locked. The only thing offered was a comparison with other subscribers. Save your money and stick with the free app. You get zero for an upgrade. Also. They do not answer e-mails. My contact here was Adrian Baritt. However, I-Tu Es came to my rescue with a refund.
