The app, called TraceMe, promises to provide fans with inside looks at their favorite celebrities. Wilson will be the first subject, with other athletes said to be on deck.
"I want to connect directly with my most passionate fans -- my superfans," Wilson told ESPN.com. "I want to provide them a front-row seat, right by my side, as I go on this journey -- no matter where they may be. And I'm not the only one. Many of my friends, from athletes to entertainers, say they'd love this too."
Wilson -- who has 4.2 million followers on Twitter, 3 million followers on Instagram and 2.2 million likes on his Facebook fan page -- said the app will show fans more than what he traditionally shares on social media.
Initial content during the beta test will include a weekly podcast from Wilson, his interviews with other athletes, and access to his team, including his mental coach, Trevor Moawad, his trainer, Decker Davis, and his cook, "Chef Andrea."
"It's more like an intimate dinner table conversation with the people you're most passionate about," Wilson said. "It's about storytelling and sharing moments, exchanging ideas and trying to become better people in the process. If it has the impact I'm hoping for, perhaps it will also influence journalism."
TraceMe has raised $9 million from an impressive list of investors, including Madrona Venture Group, one of the original backers of Amazon; Bezos Expeditions, the personal investment company of Amazon founder Jeff Bezos; YouTube founder Chad Hurley; Alibaba founder Joe Tsai; and Wheels Up founder Kenny Dichter.
