Only domestic apps are geofenced Domestic sports betting apps available in states with legal sports betting are always geofenced. This restriction is due to the Federal Wire Act of 1961. However, because offshore sportsbook sites aren’t bound by the Wire Act, there is no geofencing in play at these venues. This means you can get greater access and enjoy greater convenience, but it also means that the betting odds for your favorite local teams won’t be skewed by any hometown favoritism at your sportsbook. More accessible wagers with better payouts: That’s what you get when you use iPhone to bet sports online.
