A Steam library is only as useful as the workflow around it. The recent story about a Chinese clone of “Bills Must Be Paid” launching weeks before the original demo was a reminder that storefronts move fast and the only constant is the library you own. The Android side of the Steam experience splits across several Valve and third-party apps: the main mobile client, the chat client, the streaming client, the two-factor authenticator, and a small constellation of third-party tools that fill in price tracking, completion tracking, and library organization. The seven apps below cover the practical Steam workflow on a phone in 2026.
What to look for in a Steam companion app
Most Steam users on Android need to do four things from their phone, and the right pick depends on which one matters most:
- Library management. Browse owned games, queue installs to the PC, manage wishlist and queue.
- Chat and friends. Voice and text chat with the Steam friends list and join party invites without opening the desktop client.
- Two-factor authentication. Approve every Steam transaction with the mobile authenticator. Valve makes this functionally mandatory for any real account.
- Library streaming. Stream installed PC games from the home network or remote.
Valve owns the first four jobs through three separate apps. Third-party tools fill in price history, how-long-to-beat times, achievement tracking, and library export.

The 7 best Steam companion apps for Android in 2026
1. Steam, best for library, store, and mobile authenticator
The official Steam mobile app is the everyday driver. Browse the store, check the daily and weekly deals, queue installs to a PC sitting at home, approve trade and market transactions through the Steam Guard mobile authenticator, and read news from followed publishers. The 2025 rewrite finally gave the app a UI that does not feel like an afterthought, and the queue-install feature now works as well as the Xbox or PlayStation equivalents.
The mobile authenticator is the headline. Any account that does anything in the market or community needs Steam Guard, and the mobile version is the only way to get it. This alone justifies the install for every Steam user.
Where it falls short: Voice chat is not in this app; that lives in Steam Chat. Big library views (filtering by tag across hundreds of games) feel cramped on small screens. Some legacy Big Picture features are not yet ported.
Pricing:
- Free.
Bottom line: Required for any Steam account. The mobile authenticator alone is non-negotiable.
2. Steam Chat, best for voice and text chat
Steam Chat is the dedicated chat client Valve broke out of the main Steam app years ago and never folded back in. Voice channels, text chat, group conversations, and reactions all live here. The Android build mirrors the desktop chat sidebar; switching devices keeps history in sync.
For anyone who plays cross-platform with friends or coordinates on Discord-equivalent terms inside Steam, this is the right install. Notifications fire promptly and the voice quality holds up over typical home Wi-Fi.
Where it falls short: Voice channels are not as feature-rich as Discord’s; no soundboards, no native video. The notification model occasionally batches messages on lower-end Android devices. Some legacy chat features still live in the main Steam app.
Pricing:
- Free.
Bottom line: Worth installing if your gaming group lives inside Steam. Skip if everyone has moved to Discord.
3. Steam Link, best for streaming your Steam library
Steam Link is Valve’s official streaming client. Sign in on the same Steam account as the PC at home, the app discovers the PC over the network, and any installed Steam game streams to the phone. Big Picture mode is the on-screen UI; Bluetooth controllers, the Steam Controller, and the on-screen touch overlay all work.
Inside a home network this is the lowest-friction way to play a PC library on the couch with a phone screen. Steam Link Anywhere lets the same workflow run over the internet, with quality dependent on the host’s upload bandwidth.
Where it falls short: Streaming non-Steam launchers (Epic, GOG, emulators) requires adding them as Non-Steam games first. Some games with anti-cheat hooks have known issues with Steam Link’s input capture.
Pricing:
- Free.
Bottom line: Free with any Steam account and an internet connection. Skip only if you do not stream.
4. Steam Authenticator (inside Steam app), best for two-factor on every transaction
The Steam Mobile Authenticator is not a separate app in 2026; the feature lives inside the main Steam Android app. Activate it once, then every market sale, trade, store purchase, and important account change is approved through a push notification on the phone. Recovery codes are the only way back if the phone is lost.
This is the security backbone of a Steam account. Trading, marketplace selling, and gifting all require the mobile authenticator to be active for at least seven days. Disabling it locks accounts out of those features.
Where it falls short: Recovery codes need to be saved somewhere safe at setup; losing the phone without recovery codes is a slow path through Valve support. Some users still want a standalone authenticator app, which Valve has not shipped.
Pricing:
- Free, included with the Steam Android app.
Bottom line: Turn it on the day you create the account. Save the recovery codes in a password manager.
5. HowLongToBeat, best for game length lookup
HowLongToBeat is the unofficial third-party app for the popular community site of the same name. Search a game, see the median time to complete the main story, the main plus extras, and the 100% completionist run. The Android version supports a personal library so you can mark games as playing, completed, or on the backlog.
For anyone who actually plays through their library rather than buying and shelving, this is the planning tool. Knowing a game is a 60-hour commitment before starting changes which game you pick next on a weekend.
Where it falls short: Time estimates are community-submitted, so newer games take a few weeks to settle on accurate numbers. Some indie titles have small sample sizes. The app pulls from the website’s API, which occasionally rate-limits during peak hours.
Pricing:
- Free with ads.
- Premium subscription removes ads.
Bottom line: Worth installing for any Steam user with a sizable backlog. Skip if you only buy new releases at launch.
6. AugmentedSteam Watcher, best for price drop tracking
AugmentedSteam Watcher is the Android companion to the popular Augmented Steam browser extension. Sync your wishlist over, set price ceilings per title, and get push notifications when historical low prices appear during sales. Track keys across the ecosystem (Steam, Humble, Fanatical, GMG) in one view.
This is the right pick during sale seasons. The price history per game is the feature that pays for itself; knowing the historical low keeps you from buying at a mediocre 25% discount on a game that routinely drops 60%.
Where it falls short: The mobile app is a thinner wrapper around the web product than the desktop extension. Notification reliability depends on the phone’s battery optimization settings. Some smaller key sellers are not tracked.
Pricing:
- Free with optional donations.
Bottom line: Install it before the next Steam sale. Skip if you only buy games at launch.
7. GameSheet, best for library organization and notes
GameSheet is the niche third-party app for serious library organizers. Import your Steam library, tag games by genre, mood, length, and play status, attach notes per game, and build custom lists (“co-op weekend”, “single-player commute”, “RPGs left to finish”). The result is a personal database that the Steam client itself does not provide.
This is the most situational pick on the list. Most owners do not need this level of organization; a few owners with hundreds of unfinished games find it essential.
Where it falls short: Setup takes an evening for a large library. Sync is one-way from Steam to GameSheet; changes inside GameSheet do not propagate back. Some advanced features sit behind a one-time purchase.
Pricing:
- Free with optional one-time purchase for advanced features.
Bottom line: A small-audience pick. Skip unless your backlog has hit “I forgot I own this” levels.
How to pick the right one
Most Steam owners need three of these, not seven. A typical setup:
- Always install: the official Steam app (includes the mobile authenticator).
- For chat: Steam Chat if your group uses Steam, Discord otherwise.
- For streaming: Steam Link.
- For sale tracking: AugmentedSteam Watcher.
- For backlog planning: HowLongToBeat.
- For library organization: GameSheet, only if your backlog is large enough to need it.
The two-app minimum is Steam plus one of Steam Chat or Steam Link. Everything else is situational.
FAQ
Is the official Steam Android app free?
Yes. The Steam mobile app is free on Android. It requires a Steam account to sign in and is the only way to enable the Steam Guard mobile authenticator, which Valve effectively requires for trading and marketplace activity.
Can I stream Steam games to my phone away from home?
Yes, using Steam Link Anywhere. The host PC must be powered on and running Steam, and the phone needs a strong cellular or remote Wi-Fi connection. Quality depends on the host’s upload bandwidth; 10 Mbps up is the recommended floor.
Do I need the mobile authenticator on my Steam account?
To trade, sell on the marketplace, or gift games, yes. To just play games, no. Most active Steam users enable it the day they open the account, because Steam Guard adds significant security and is required for the community features.
What is the best app for tracking Steam sales?
AugmentedSteam Watcher tracks both Steam and a broader key-reseller ecosystem and shows price history. IsThereAnyDeal is the alternative as a browser bookmark; the Android-specific apps split user preference roughly 50-50.
Can I see my Steam achievements on Android?
Yes, inside the official Steam Android app under each game’s page. For deeper tracking (rare achievement leaderboards, completion percentages), the website on a mobile browser still has more depth than the app.
