Its BS. 
That pic they show is deceptive. That person is totally misrepresenting the product. I dont know how they can do that and Google allows them to advertise with adwords…
I would also bet that the email you recieved was from their marketing efforts….
It is a horrible poker calculator.
I myself have a MUCH better product thats just out of beta that tracks cards, outs, player actions, etc.. but alas – it wont show you others cards…..
Bottom line – verified fraud and total BS – dont waste your cash.
