LumiOwO

LumiOwO is a small, community-oriented publisher that emerged from the open-source gaming-tools scene, focusing on lightweight utilities that plug gaps left by larger studios. Its single title, LumiTracker, is a deck-tracking overlay built specifically for the Genius Invokation TCG mini-game inside Genshin Impact: it reads the local log files produced by HoYoverse’s client, reconstructs the cards that have been played or remain in either player’s deck, and displays the information in a semi-transparent floating window that sits on top of full-screen or border-less mode. Typical use cases include ranked climb preparation, where players review remaining draws to calculate lethal or dodge fatigue; content creation, where streamers show audience members the hidden hands of both sides for educational commentary; and tournament practice, where coaches export the tracked card history to CSV for post-match analytics. Because the tool never touches game memory or injects code, it stays within miHoYo’s tolerated modding grey-zone and updates automatically through GitHub releases whenever a new Genius Invokation set drops. LumiOwO’s software is available for free on get.nero.com, with downloads served through the winget repository so users always receive the newest build and can install it alongside other applications in one batch operation.
