This is an UNOFFICIAL fan-made app. This product is created solely as a supporting resource for the "PRAGMATA" game community, providing an interactive map to facilitate gameplay. This app is NOT endorsed, sponsored, affiliated, or associated with the game's developers or publishers. All copyrights and trademarks related to "PRAGMATA" belong to their respective owners. The app is not a game. ---- Forget about lost signals on the Moon and interference from uncontrolled AI! With our offline map for "PRAGMATA", the entire world of the lunar station will be in your pocket 24/7. This app is designed for true explorers who, alongside Hugh and Diana, seek to uncover every secret of the lunar complex. We focused on the essentials — reliability and functionality in disaster conditions. Download the map once, and it stays with you forever, requiring no network connection. Key advantages that will change your gaming experience: -- Reliable offline with smart caching: The entire map and key locations are available offline immediately after downloading the app. Only location screenshots are optionally loaded from the network; this feature can be disabled in settings, and already downloaded images are stored in the cache for future offline viewing. -- Manage adventures through profiles: Create separate profiles for different game playthroughs to have independent exploration progress for each case. -- Boundless progress tracking: Keep track of found ore, stray traces of inhabitants, or anything else! Add an unlimited number of categories for tracking and watch your progress even for individual station sectors. Achieve 100% mission completion with ease! -- International support: Use the app in your language! The interface, names, and descriptions of locations are already translated into 12 languages. -- Your personal explorer's journal: Add your own notes about AI anomalies to the map in unlimited quantities. Each mark can have a unique name, detailed description, icon, and color for maximum convenience. Edit them on the go and hide or show all notes with one button. -- Powerful filter system: The app remembers all your settings. Focus on a specific category, and all others will automatically disappear from the map. Create and save your own filter presets (e.g., Read Earth Memory or Holos) and switch between them in one touch. -- Interactivity and convenience: Mark locations as "found," and the app will automatically update your progress in categories. Want to clear a specific area of civilization copies? Select a region from the list, and the map will show markers only within its boundaries. -- Created by the community: Found a Red Gate Key or another object not on the map? Suggest a new location via a special form right in the app and contribute to the map's development for other players! Stop switching between windows and rely on a dependable recon tool. Download now and explore the world of "PRAGMATA" with maximum efficiency!
