One Underdog app now has to do the work of three separate products. That is a different question than "does Underdog have an app" was back when the company ran a pick’em game and nothing else. The install is the same single thing on the App Store and Google Play — what changed in 2026 is everything it has to gate once it is open.
What’s Actually Inside the App Now
Open it today and there are three products stacked behind the same login: Classic Pick’em, the original over/under projection game; Pick’em Champions, the peer-to-peer version Underdog had to license state by state starting with New Jersey and Delaware in March 2025; and Predict, the CFTC-licensed prediction-market exchange that launched in July 2026 on Underdog’s own Designated Contract Market registration. The sportsbook that used to round out the lineup is gone — Underdog closed it nationwide in December 2025 and settled every outstanding North Carolina wager rather than keep fighting for more licenses.
Three products, three legal maps, one app. The app itself installs the same way everywhere. Whether it lets a given phone fund Classic Pick’em, Pick’em Champions, or Predict depends on location services checking three different approval lists, not one blanket "Underdog is live here" switch.
Store Ratings and the Official Listing
Underdog Fantasy Sports is the listing name on both platforms, published by the company rather than a third party. Independent DFS comparison sites following it through 2026 commonly put it around 4.8 stars on the Apple App Store and roughly 4.6 on Google Play — both solid numbers for a real-money app, and reviewers on both platforms single out the interface as a strength rather than a weak point. Treat any specific figure as a snapshot; the live store page is always the current one.
The Only Download That Is Actually Underdog
Search "Underdog Fantasy" inside the Apple App Store or Google Play and install from there. Underdog does not distribute a standalone APK for Android, so any site offering an "Underdog APK" direct download is not the company — sideloading one skips Google Play’s review step entirely and hands install permissions to code nobody can verify. This is a counterfeit-file risk, not a sign that Underdog lacks a real app; unlike an offshore sportsbook locked out of US app stores, Underdog has nothing to work around here.
Who the App Actually Fits
Anyone wanting pick’em-style DFS where it is actually offered can use the app for Classic Pick’em or Pick’em Champions — just confirm which one is approved in their state, since the two have different lists. Anyone looking for Underdog’s old sportsbook inside the app will not find it; that product is retired. Anyone curious about Predict is opening a federally licensed exchange product closer in kind to Kalshi than to a pick’em contest, and it carries its own availability questions the app will enforce the same way it does the other two.
