Softonic’s write-up of the Foundation board game announcement (a spin-off targeting winter 2026 on Gamefound) landed as most of us were still tracking a shelf of sci-fi titles that all lean on a companion app. Twilight Imperium, Dune: Imperium, Nemesis, Star Wars: Rebellion, Root’s Landfall expansion; every recent release ships with rules that reward a tracker on the side and a rules teacher for the newcomer. The best apps for sci-fi board game companions on desktop in 2026 are the ones that survive four hours of play, keep the score legible, and let you check a rule without opening a PDF. This list covers the catalogue, the trackers, the rules teachers, and the online tables where you can rehearse a game before pitching it to the group.
What to look for in a board game companion app
Catalogue coverage decides half of it. Modern sci-fi titles land quickly on BoardGameGeek and slower on the niche trackers; a companion app that syncs your BGG collection saves a re-entry per box.
Rules teaching separates a companion from a database. Dized is the modern standard; some publishers ship official interactive rules alongside the box, others don’t.
Score-tracking flexibility matters. Twilight Imperium runs eight-hour sessions with several dozen tracked numbers; a general-purpose tracker that supports templates beats a purpose-built one you’ll outgrow.
Digital-first play is the parallel track. Board Game Arena and Tabletopia both host large sci-fi catalogues; playing once online before your first table night is the fastest way to learn a heavy title.
Campaign state persistence carries campaign games. Gloomhaven Helper, ISS Vanguard, Frostpunk: The Board Game and the incoming Foundation title all reward a companion app that saves state between sessions.

The apps
1. BoardGameGeek, best for the catalogue and rulings archive
BoardGameGeek is the reference library, and it’s a web app first. Every recent sci-fi release has its own page with a searchable rules forum, an expansion catalogue, a “how to play” video pool, and community strategy notes. Sign in once from the browser and every companion app on this list can sync your collection through the BGG API. The Foundation entry appeared within a week of the Gamefound announcement, which is the pattern.
Where it falls short: the UI is a period piece. Mobile is thinner than the web on desktop.
Pricing: Free. BGG Supporter is around $30 a year and removes ads.
Platforms: Web on Windows, macOS, Linux.
Download: BoardGameGeek
Bottom line: The starting point for any tracker or teacher below. Sync it once, everything else gets easier.
2. Board Game Stats, best for score tracking and session logs
Board Game Stats is the tracker most heavy players settle on. Templates for score categories, session length, turn order, and player rating carry the load across everything from Terraforming Mars to Twilight Imperium. Syncs to BGG, exports session logs to CSV, and holds up over eight-hour game nights without losing state.
Where it falls short: the desktop experience is a browser wrapper around the mobile app. Some templates need manual editing per game.
Pricing: Free tier. Premium is around $8 a year.
Platforms: Web, Windows and macOS via wrapper. Native on Android and iOS.
Download: Board Game Stats site
Bottom line: The right tracker when scores are half the reason you play.
3. Dized, best for an interactive rules teacher
Dized partners with publishers to ship interactive rulebooks. Instead of reading a PDF, you tap through a decision tree that teaches setup, then hands you an FAQ for edge cases mid-game. Coverage is uneven but growing, and every recent sci-fi 4X release has been an early Dized partner.
Where it falls short: not every publisher ships a Dized rulebook. When they don’t, you’re back on the PDF.
Pricing: Free rulebooks for many titles. Premium subscription is around $5 a month and covers additional partner content.
Platforms: Web, Windows, macOS.
Download: Dized site
Bottom line: The first thing to check before you unwrap a heavy new title.
4. Tabletopia, best for online play across the widest catalogue
Tabletopia hosts a huge digital catalogue as unassisted tables. Unlike Board Game Arena, rules aren’t enforced by the software; you play as if you were at a physical table, which is how expansions, prototypes and community mods land here first. It’s the standard for trying a heavy sci-fi title before you buy the box.
Where it falls short: no rule enforcement means a bad-faith player can cheat; play with people you know. The camera controls take an evening to get used to.
Pricing: Free with a limited catalogue. Bronze (around $5/mo) opens most content; Silver and Gold are around $10 and $20 a month.
Platforms: Web, Windows, macOS.
Download: Tabletopia site
Bottom line: The pick when your group is remote or you want to try a title before buying.
5. Board Game Arena, best for fast asynchronous online play
Board Game Arena is the opposite of Tabletopia: rules are enforced by the software, matchmaking is fast, and you can play asynchronously across a week if the group can’t meet live. Sci-fi coverage skews to euros (Dune: Imperium, Terraforming Mars: Prelude 2, Andromeda’s Edge) rather than dice-heavy Ameritrash, which is the tradeoff for enforced rules.
Where it falls short: no unenforced play. If a title isn’t implemented, it isn’t playable here.
Pricing: Free with a rotating title access. Premium is around $4 a month with unlimited access to premium titles.
Platforms: Web on Windows, macOS, Linux.
Download: Board Game Arena site
Bottom line: The pick for a quick sci-fi euro over lunch or across a work week.
6. Gloomhaven Helper, best for campaign game state management
Gloomhaven Helper (the modern community-maintained fork after the original went commercial) manages monster stats, initiative, character conditions and party state through a campaign. The community fork extends to Frosthaven, Jaws of the Lion and a growing set of scenario sets that campaign-shaped sci-fi titles have started to borrow.
Where it falls short: single title family (Gloomhaven and friends). Not the tool for a fresh sci-fi campaign game unless a companion fork exists.
Pricing: Free open source.
Platforms: Web on Windows, macOS, Linux. Companion Android and iOS clients.
Download: Gloomhaven Helper (Havenmarker community build)
Bottom line: The one to install if you play the Haven series, or a template for what a sci-fi campaign game companion should look like.
7. Notion, best for a fully custom campaign log
Notion is the fallback when nothing off the shelf fits: a Foundation campaign, a house-ruled Twilight Imperium mega-game, or a group log for a Nemesis Aftermath season. Templates cover session recaps, per-player win history, and a house-rules index that survives an expansion. A free Notion workspace covers most home-game needs.
Where it falls short: no templates ship with the app; you’ll build the first one. Doesn’t teach rules or enforce them.
Pricing: Free personal plan. Plus is around $10 per user per month.
Platforms: Web, Windows, macOS, Linux.
Download: Notion site
Bottom line: Best when the group’s log is bigger than any tracker and you need one page per campaign.
How to pick the right one
For the catalogue and rulings: BoardGameGeek. Sync it first.
For live score-tracking and post-game history: Board Game Stats.
For teaching a heavy new title on the same evening you unbox it: Dized.
For remote or preview play at the widest catalogue: Tabletopia.
For enforced-rules online play in half an hour: Board Game Arena.
For campaign titles with persistent state: Gloomhaven Helper (or a template you build in Notion for a title Gloomhaven Helper doesn’t cover).
For a house-rules mega-game or a Foundation-style campaign that runs across months: Notion.
FAQ
Will Foundation ship with an official companion app?
The Gamefound announcement mentioned a companion tool in the stretch goals but not the base pledge. A community app (either on BGG’s dev network or as a Gloomhaven Helper fork) is likely to appear if the publisher’s build slips.
Which app covers the most modern sci-fi titles?
BoardGameGeek’s catalogue is complete. Dized coverage grows with publishers. Tabletopia and Board Game Arena diverge: Tabletopia has more titles, Board Game Arena has better play.
Do I need to pay for any of these?
Free tiers of BGG, Board Game Stats and Board Game Arena cover most home groups. Dized’s rulebooks for supported titles are free. Tabletopia’s free tier is a fair preview; Bronze is worth it once you play weekly.
Can these apps work with expansions?
BGG and Board Game Stats treat expansions as inline additions. Tabletopia and Board Game Arena implement expansions per title; check the specific expansion’s status before assuming coverage.
Is there a companion app for Twilight Imperium 4th Edition specifically?
Board Game Stats has a working TI template, and Twilight Companion (a fan project) tracks tech, objectives and strategy card selection. Neither is official; both work.
