I'm so glad that only Apple products can be used to count cards...
WHEW!
Besides... card counting is easy. which is why Casinos go to extreme lengths to prevent the effective use of card counting. They change dealers often and use multiple packs (5+) to make the odds even out.
Ever since they introduced electronic card shufflers though, the rules changed. Some purists believe that the shufflers can scan each card and thus issue cards that can influence the outcome of the dealer's draw.
So at "high roller" tables the players "request" that they use the old shoe and old fashioned dealer to ensure that there's no funny business... after all, the casinos don't allow anyone to inspect the card shufflers and they "destroy" them as opposed to simply chucking them out.
I know because I've asked to get one for when we play poker at home... the commercially available card shufflers are nothing more than "card-flinger-togethers" which don't work at all!
No way...
Anyway...
Funny how its only the Apple products.
A simple calculator (available on most smart phones) could be used to count cards...
Or just keep count! its not that hard at ALL!
A simple technique is:
+1 for high cards
-1 for low cards
The lower the number in your head (or iPhone), the more high cards remaining in the shoe.
LOL - you still need to know what you're doing!
