OGM

Overview

OGM is an unofficial companion app for interactive maps of game worlds, not a game. It is best for players who want to keep regional progress and custom map notes organized across separate playthroughs. Its main strength is that downloaded maps and core data work offline, while route planning is not part of the package.

Key features

The library brings together dozens of game maps, with new worlds added regularly. Download maps and core data before going offline; network access is required for new or updated maps, and location screenshots need a connection the first time they load. That makes OGM useful away from reliable connectivity, provided players prepare first.

Separate profiles keep playthroughs distinct. Players can create unlimited tracking categories and follow progress by map region, then add unlimited notes and markers with names, descriptions, icons and colors. Saved filter presets switch with one touch. These tools offer more than a basic map viewer, though players looking for route planning should choose another tool.

The interface is translated into 12 languages. Account-based automatic sync sends progress to Firebase servers; OGM says that data is private to the linked account. Registration is optional: OGM Hub can export and import progress offline. Still, players who do not use sync need to preserve an export file, because uninstalling without either backup permanently deletes progress.

The privacy policy names Google Play Services, AdMob, Google Analytics for Firebase, Firebase Crashlytics and Unity as third-party services. It says commercially acceptable protections are used but cannot guarantee absolute security. Players should weigh that caveat when deciding whether to sync progress.

Pricing

The free plan costs 0.00 USD per free and includes offline maps, markers and tracking, but is ad-supported. It suits players who can tolerate ads and want the core map and progress tools without paying.

All three paid plans remove ads. Monthly Premium costs 1.99 USD per month, billed monthly; it fits someone who wants an ad-free option without a longer commitment. Yearly Premium costs 7.99 USD per year, billed yearly, for players who expect to use OGM over time. Lifetime Access costs 29.99 USD per once, billed as a one-time purchase, for users who prefer not to renew. The free tier gives up ad removal, while the paid tiers are differentiated by payment term rather than additional features in the plan descriptions.

Platforms

OGM is available on Android, iOS and macOS. The App Store listing requires iOS 15 or later and supports macOS 12 or later on Macs with an Apple M1 chip or later. It is a mobile-oriented choice; players seeking a web app or desktop access beyond supported Macs should consider another option.

Who it's for

OGM is a good fit for players managing multiple game playthroughs who want regional checklists, flexible markers and offline map access in one library. Its unlimited categories and markers are useful for detailed personal tracking. It is less suitable for anyone who needs route planning, or who wants progress to survive an uninstall without enabling sync or making an export.

Pros and cons

Verdict
