The BetMGM app has two ratings, and they disagree. On the Apple App Store it sits around 4.8 out of 5 from more than 240,000 reviews — the kind of number that looks decisive. A 2025 RotoWire survey that asked actual bettors to rate the experience, rather than counting whoever left a store review, put it at 3.51 out of 5. Neither figure is wrong. They’re measuring different populations at different moments, and a reader deciding whether to download BetMGM’s app should know both exist before picking one to believe.

The Rating Gap, Explained

Store ratings skew toward people rating right after signup, often while a welcome bonus is still fresh and goodwill is high. RotoWire’s survey instead asked bettors to score categories separately — user experience, promos, functionality, app features, and a miscellaneous bucket. Functionality came out highest at 3.94, with the reviewer calling BetMGM “one of the most reliable platforms in the industry.” App features scored lowest, 3.07, the category dragging the overall average down to 3.51. Read together: the app rarely crashes, but regular bettors don’t think its feature set leads the category the way its 4.8 stars would suggest.

  • Apple App Store: ~4.8/5, 240,000+ ratings (third-party tracking, 2026)
  • Google Play: ~4.2/5, 36,000+ ratings (third-party tracking, 2026)
  • RotoWire bettor survey (2025): 3.51/5 average — functionality 3.94, app features 3.07

One App Since 2021, With a State Switcher

BetMGM used to run separate apps per state before consolidating into a single build in 2021. That matters for anyone who travels: a user with an account in New Jersey who flies to Michigan doesn’t need a new install, just a state switch inside the same app and, where allowed, a new state-specific account. The app verifies physical location through GPS, WiFi, and IP data every session — not only at registration — and reviewers warn that trying to spoof that location to bet from an unlicensed state is a terms violation that can get an account closed and reported to the relevant regulator, not just quietly blocked.

The MGM Rewards Bridge

This is where BetMGM’s app does something DraftKings and FanDuel structurally can’t: tie into an actual casino loyalty program with physical resorts behind it. A redesigned in-app rewards dashboard shows a live BetMGM Rewards Points balance and tier progress, and a Rewards Store lets a user spend points on digital bonuses or additional MGM Rewards Points without leaving the app. Every settled bet shows the points it earned. Reviewers covering the casino side of the program describe two parallel currencies — BetMGM Rewards Points and MGM Rewards tier credits — with tier status carrying toward perks at physical properties like MGM Grand Detroit. That link to a Las Vegas-rooted rewards program is a real differentiator; it’s also not something the app can offer anyone who never sets foot in an MGM property.

Bet Builder and cash out are both in the app: Bet Builder combines markets from a single matchup into one same-game parlay with correlated legs priced automatically rather than simply multiplied together. Cash out is available on eligible wagers from the bet slip or My Bets, letting a bettor settle a position — in full or partially — before a game ends.

Download, Then Location Decides the Rest

Installing the app is free and available anywhere in the US on either store. What it unlocks after opening depends entirely on where the phone is standing: the sportsbook reaches roughly 23 states plus Washington D.C. as of September 2026, while the online casino is confined to Michigan, New Jersey, Pennsylvania, and West Virginia — a state having the sportsbook says nothing about whether it also has BetMGM Casino. A download succeeding in a state without either product doesn’t mean either product is actually live there once the app opens.

Bottom Line

“Does BetMGM have an app” is a clean yes, officially listed on both stores with no sideloading required. Which rating to trust is the more interesting question: the 4.8 App Store score and the 3.51 bettor-survey score are both honest, they just measure different things, and a reader comparing sportsbook apps should weight the survey more heavily than the stars. Treat any of it as entertainment, not income — 21+ and only where BetMGM is actually licensed to operate. 1-800-GAMBLER if it stops feeling that way.
