International Game Technology (IGT) supports the Oneida Nation's retail and online sports betting products at its Oneida Casino in Green Bay.

You can bet on a phone app as long as you are on an Oneida property. And I suppose I could have tracked my bets on March Madness if I had placed them with the App. But I would have still needed to come back to the casino to cash out, or mail SASE, ID, Social, and who knows what else.

Wisconsin has no legal sports betting, except at the Tribal Locations.
