Companion apps turn board games into hybrid experiences by handling rules, scoring, tutorials, and hidden information on your phone or tablet.
Board game companion apps do different jobs depending on the title. Some walk you through setup and rules. Others replace the game’s physical components entirely or keep a player’s private hand hidden from the table. Figuring out how to play board games with companion apps starts with knowing which kind you’re dealing with, because the workflow differs sharply between a rules-tutorial app and a multiplayer controller app.
For anyone ready to put these tools to work tonight, the fastest payoff comes from the apps built for specific games. Play the right one and you’ll spend less time fumbling with a rulebook and more time actually playing.
What a Companion App Actually Does During Play
Think of companion apps in three broad buckets, though many blend these roles. First, the rules and tutorial apps like Dized, which walk you through setup and teach you how to play. Many even feature built-in searches for rules, so you can look up a specific situation mid-game without breaking pace.
Second, there are component replacement apps that swap physical pieces for digital ones. You might use one to roll dice, draw cards, or track scores.
Third, there are controller apps for games that run on a shared screen, like a TV or a tablet. A few of these genuinely transform the experience by keeping sensitive data off the central display, which solves the classic problem of everyone seeing what you’re holding.
Gameboard Companion: The Shared-Screen Multiplayer App
Gameboard Companion: Join Play is a strong example of the controller model. It lets local or remote players join a Gameboard game, participate in the game stream, throw digital dice, and play digital cards. The key feature is privacy: your personal gameplay information stays on your phone, never on the shared screen.
This app is free on the App Store and requires iOS 11.0 or later on iPhone, iPad, and iPod touch, macOS 11.0 with an Apple M1 chip or newer on Mac, and visionOS 1.0 or later on Apple Vision.
The core workflow looks like this: one player hosts the game on the main screen, and everyone else opens the app on their own device. You join via a game code and then use your phone as your private control panel. Your cards, dice, and secret information stay accessible only to you.
Cluesheet Companion: How to Set It Up for Cluedo
Cluesheet Companion is the official local multiplayer app for Cluedo: The Classic Mystery Game on Nintendo Switch and Steam, and it’s an excellent demonstration of how to play board games with companion apps in a specific title. It’s designed for local multiplayer only — not single-player mode — and it supports up to six smartphones as controllers.
Here’s the official setup sequence:
- Launch Cluedo: The Classic Mystery Game on your Nintendo Switch or Steam.
- Select Play with Friends from the main menu and host a local game.
- Open the Cluesheet Companion app on your phone, enter the passcode, and join the lobby.
Once you’re in, your phone becomes your private Cluesheet — perfectly suited for the game’s deduction mechanics, where hidden information is the entire point. The app requires iOS 11.0 or later and works on iPhone, iPad, iPod touch, and Apple Vision.
How to Pick the Right Companion App for Your Game
Most companion apps are game-specific rather than universal, so check the app’s store page against your exact board game before you commit. Dized is the notable exception to this rule, functioning as a broad rules repository for card games, board games, miniature games, and RPGs. Its Google Play listing confirms the rules are publisher-approved and identifies the developer as Playmore Games Oy.
| App | Best For | Key Limitation |
|---|---|---|
| Dized | Rules lookup, tutorials, and search across many titles | Not a controller for live play |
| Gameboard Companion | Shared-screen play with private info on phones | Requires a Gameboard game to host |
| Cluesheet Companion | Cluedo local multiplayer on Switch or Steam | Local multiplayer only — no single-player |
Before downloading, confirm the app matches your specific game title and your platform — Switch, Steam, iOS, or Android. Also check whether it expects a shared-screen host or works entirely on your device, since that changes how many phones you’ll need on game night.

FAQs
Do companion apps need an internet connection?
Not always. Several companion apps, including Cluesheet Companion for Cluedo, operate entirely over a local connection to a nearby console or Steam host, with no internet required once everything is running. Apps that support remote play, like Gameboard Companion extending a game to players outside your home, do need a working internet connection.
Can one phone run a companion app for a whole group?
Some apps work fine with a single shared phone, especially rules guides like Dized where one person reads instructions aloud. Controller-style apps that protect hidden info are a different story — they typically assume one phone per player, since passing a single device around is impractical in a game where secrecy matters.
How do I know if a companion app is official or fan-made?
Check the app’s store listing and the game’s official website. Official apps usually carry the publisher’s name in the developer field and sometimes the word “official” in the title. A description mentioning publisher approval, like Dized’s “publisher-approved rules,” is another solid signal of legitimacy.
