OGM vs TH.GL

OGM is an unofficial fan-made app for browsing interactive maps of game worlds; it is a map tool, not a game. Its library brings together dozens of maps and adds worlds regularly. After maps are downloaded, they and core data work offline, but network access is needed for new or updated maps and for initially loading location screenshots. Players can keep separate profiles for different playthroughs, track progress by region, and create unlimited tracking categories, notes, and markers with names, descriptions, icons, and colors. Saved filter presets can be switched with one touch, and the interface is translated into 12 languages. An account can automatically sync progress to Firebase; registration is optional, and OGM Hub offers offline export and import. Without cloud sync or a manual export, uninstalling permanently deletes progress. The free plan is ad-supported; paid plans remove ads. OGM is available on Android, iOS, and macOS.

TH.GL is a game-mapping service with interactive maps, companion tools, overlays, and position tracking. Maps can show nodes, collectibles, NPCs, and resources, with filters, custom markers, and routes that users can share. Its standalone Companion App supports 32+ games and detects a supported game automatically. It can display in-game maps and minimaps with live position and nearby points of interest, and users can customize hotkeys. Peer Link can mirror the map and live position to a phone, tablet, or other device. Web maps work on any device without a download, but omit overlays and position tracking. The maker describes the Companion App as read-only, locally run, and account-free, and says it has developer approval for Dune: Awakening, Once Human, and Palia. The app is free with ads; supporter plans remove ads. The Free plan is free, and Enthusiast is $2 a month, billed Free for the first 3 months.
