Before players are able to bet on the app, state law requires them to register in-person at any of the three Wild Rose casinos where the operator launched its sportsbooks last October.
Bettors will be able to use the app from anywhere in Iowa once registered.
After 1 January 2021, customers will no longer be required to register in-person.
Matt Kalish, President and Co-Founder of DraftKings North America, said: “DraftKings has seen steady fan engagement in Iowa during the last few months at our three Wild Rose sportsbooks across the state, and we couldn’t be more excited to provide customers with our state-of-the-art mobile sports betting platform.
“We have worked diligently to perfect our sportsbook product since it launched in 2018, and starting today, we’re proud to offer Iowans a safe and responsible place to wager on sports – one that can be accessed conveniently from the palm of their hands.”
In December, DraftKings announced it will acquire supplier SBTech in a deal worth an estimated $3.3bn in market capitalisation.
Speaking with Gambling Insider earlier this week, DraftKings CEO Jason Robins outlined plans to keep SBTech’s senior management ps at the company once the two firms have merged.
