What Is a Gaming Companion App and How Does It Work?

Updated

A gaming companion app is a standalone desktop program that runs alongside your game and adds a layer of information on top of it — typically an in-game overlay, live position tracking, and interactive maps. On TH.GL, the Companion App is a Windows 10/11 download of about 7MB that requires no account and supports 37+ games, while the same site's browser-based tools cover 50+ games. Install the app when you want overlays and real-time tracking without alt-tabbing; stay in the browser when you only need to look up a map or database occasionally.

Companion App vs. Browser Tools

Both options draw on the same interactive map and database content. The difference is how the information reaches you while you play.

Dimension Companion App Browser-Based Tools
Form Standalone Windows 10/11 program Web page in any browser
In-game overlay Yes — no alt-tabbing needed No
Live position tracking Yes, in real time Not described as live in-game
Second screen Dual-monitor support; Peer Link syncs a phone or tablet as a live minimap Manual lookup on a second device
Game coverage 37+ games 50+ games
Download / setup ~7MB download, no account required Nothing to install
Best for Players who consult maps constantly during play Occasional lookups, or games not covered by the app

The coverage gap matters: if your game appears in the 50+ browser list but not the 37+ app list, the browser is your only option on this site.

What the App Actually Does

In-game overlays

The overlay places map and tracking information on top of the game window, so you don't switch out of the game to check a location. TH.GL describes this as "no alt-tabbing needed."

Live position tracking

The app shows your exact position and nearby actors in real time. With Peer Link, you can pair a phone or tablet and use it as a live minimap — useful if you game on a single monitor and don't want the overlay covering the screen.

Interactive maps

Maps let you track nodes, collectibles, NPCs, and resources with filters. You can create custom markers and routes and share them with friends. TH.GL states that marking locations as discovered is unlimited and free.

Second-screen support

On a dual-monitor setup, the app can run on the second screen while the game stays on the primary one.

Requirements, Safety, and Privacy

  • Platform: Windows 10/11 only, per the site. Mac and Linux users would need the browser tools.
  • Size and account: ~7MB download, no account required.
  • Permission: TH.GL describes the app as "officially permitted" and "safe & approved." That is the vendor's own claim; if a specific game's rules matter to you, check that game's policy on overlays before installing.
  • Data handling: The site describes a local-first approach with anonymous analytics and no account, so your marker data stays on your machine rather than in a cloud profile.

Deciding Whether to Install

Install the companion app if all of these are true:

  • You play on Windows 10/11.
  • Your game is among the 37+ supported titles (the site names Palworld, Dune Awakening, Once Human, and Wuthering Waves among them).
  • You regularly want map or position information mid-session and find alt-tabbing disruptive.

Skip it and use the browser if any of these apply:

  • You play on another operating system.
  • Your game is only in the 50+ browser catalog.
  • You look things up between sessions rather than during them — a browser tab costs nothing to open.

A practical middle ground: start with the browser map for your game. If you find yourself tabbing out repeatedly during play, the ~7MB install is a low-commitment upgrade, and the no-account, local-first design means there's little to undo if you change your mind.
