I would not be comfortable using an app at this time. A couple months ago, I got nervous when the fellow sitting next to me "helped me out" by whipping out his smartphone when he saw me looking at a strategy chart for a hand that resulted in a big jackpot. It did cross my mind that there was a chance they would not pay me.
That being said, it is just a matter of time before casinos will not only tolerate the use of apps, but encourage it! I believe that people who love their tech toys, who do not gamble much, will plop down and play. The experience will be more enjoyable for them. They will be losing more slowly, because of the time it tales to look everything up.
It will help the casino's bottom line. A recent guest on "Gambling with an Edge" said when he gave strategy advice (this was for a table game, but it applies to human nature in general), people sort of wanted to know the right way to play, but still went with their "feelings."
That reminds me of when a visiting friend asked me to help him learn how to play VP. I thought he was doing really well at FPDW. This guy's no dummy, he's a Harvard law grad. So I took him to Sam's Town. The minute I turned my back, he says, "I kept seeing aces, so I held one, and look! Two more popped up!"
So, most folks with phone apps are not going to influence any casinos to tighten their paytables! People will still go with their intuition, and not follow the strategy. They will play a machine with a bad paytable, because they just know it is lucky. No app is going to help most folks beat the house.
I agree with everything Bob said. For a serious player, this is a good tool. For now, I'll be using paper charts if something stumps me, because I am chicken. Also, I am old and haven't gotten the hang of my smartphone yet.
