You're standing in line for a coffee, and suddenly your phone buzzes. It's an alert: someone just bought that Mike Trout card you listed for 140,000 Stubs. You didn't have to be sitting in front of your console. You didn't even have to be home. That is the beauty of the MLB The Show 25 companion app, a tool that has basically become mandatory for anyone serious about Diamond Dynasty or Road to the Show.
Honestly, if you aren't using it yet, you're just making the grind harder on yourself.
What is the MLB The Show 25 Companion App?
It is more than just a menu on your phone. San Diego Studio has spent the last few years turning this thing into a full-blown extension of the game. For the 20th anniversary edition of the franchise, the app received some significant under-the-hood polish. It's available on both iOS and Android, and yes, it's totally free.
The core idea is simple: let players manage their "baseball life" while they’re away from their PlayStation 5, Xbox Series X|S, or Nintendo Switch. Because let's face it, we can't all spend 10 hours a day on the couch.

The Marketplace: How to Make Stubs While You Sleep
The Community Marketplace is where the app really earns its keep. Flipping cards is the fastest way to get a "God Squad" without spending real-world money. On the console, the interface can feel a bit sluggish when you're trying to undercut a price by one Stub. On the phone? It’s snappy.
You can view your active orders, check price trends over the last 24 hours, and see exactly what the "Buy Now" and "Sell Now" prices are in real-time. It’s remarkably easy to get into a rhythm of buying low and selling high while you’re on a lunch break or watching a real MLB game on TV.
One thing most people overlook is the Watchlist. If you're waiting for a specific Diamond player's price to drop during a Flash Sale, you can tag them in the app and keep a close eye on the market fluctuations. It’s much more efficient than constantly searching the name "Paul Skenes" every ten minutes.
Face Scan: Putting Yourself in the Game
For a lot of folks, the MLB The Show 25 companion app is primarily a Face Scan machine. This feature has improved drastically since it first launched. It used to be that your in-game player ended up looking like a melted wax sculpture, but the 2025 version handles lighting and skin tones way better.
The process is pretty straightforward:
- Open the app and sign in.
- Hit the "Face Scan" tab.
- Follow the on-screen prompts to move your head.
- Upload and wait for the "Successful" notification.
Once it's uploaded, you just go into the Road to the Show (RTTS) or your Ballplayer customization screen on your console, and the "Apply Face Scan" option will be waiting for you. It adds a level of immersion that’s hard to beat when you see your own face staring back from the batter’s box.

Managing Your Squad and Programs
You've got a new pack waiting for you because you completed a program goal while playing last night? You can rip it open on the app. The pack-opening animation isn't quite as flashy as it is on a 65-inch 4K TV, but the "Diamond" flare still gives you that same hit of dopamine.
Beyond packs, you can actually manage your Diamond Dynasty lineup. If you just earned a new Captain card or a high-overall Pipeline series reward, you can slot them into your starting nine or your pitching rotation right there. You can also track your progress in Team Affinity or the XP Reward Path.
Seeing exactly how many "Stars" or "Points" you need for that next big reward helps you plan your next actual gaming session. "Okay, I just need three more Strikeouts with Reds players to finish this mission." Knowing that before you turn on the console saves you a ton of menu-navigation time.
Real Talk: The App's Quirks and Limitations
No app is perfect. Sometimes the servers get cranky, especially on Friday afternoons when a new "Content Drop" happens. You might find yourself having to log in a couple of times because it "timed out."
Also, it's worth noting that the app requires a fairly modern operating system. If you're rocking an iPhone from six years ago, you might run into some lag or find that the Face Scan feature won't trigger because of camera hardware limitations. For the best experience, you'll want to be on Android 11 or iOS 16 or later.
Why This Matters for the 2025 Season
With the 2025 edition being the first one to truly leave the "old gen" (PS4/Xbox One) consoles behind in the dust, the game's data processing is faster. This reflects in the app too. The sync between your phone and your console is almost instantaneous now.

If you are a casual player, the app is a nice convenience. If you are a competitive player, it’s a requirement. You cannot keep up with the market inflation if you only check it when you’re at home.
Actionable Steps to Get Started:
- Download the App Early: Don't wait until you're deep into the season. Get it set up during the first week.
- Set Up Push Notifications: Turn these on for "Marketplace Sales." It’s the only way to know the second your Stubs have cleared so you can reinvest them.
- Do Your Face Scan in Natural Light: Avoid overhead office lights or dark rooms. Go near a window during the day for the best results.
- Check the News Tab: SDS often drops "Scouting Reports" or hints about upcoming Flash Sales and Double XP weekends here before they go viral on social media.
The MLB The Show 25 companion app basically turns a console game into a 24/7 experience. It’s the easiest way to ensure you never miss a market move or a program deadline. Grab your phone, sign in with your PSN, Xbox, or Nintendo account, and start working that marketplace.
