Vibrate & Stealth

I would assume the vibrate and stealth features were removed due to pressure from the casino industry, or from Apple itself. While card counting is not illegal, using a device in a casino IS illegal. Either way, it clearly states in the app description that if you want the vibrate and stealth options, then DONT update. This is a great app, and as a casino surveillance employee that tries to catch card counters, I have a bit of experience in the matter.

By the way, from a gamblers perspective, this app would be more useful as a training and practice tool. Anyone with a bankroll large enough to actually count cards in a casino would probably be able to do so without help from an application.
