Tonkatsu Box

Tonkatsu Box is a free, open-source media tracker for people who want one place to manage everything they watch, play, and read. It runs on Windows, Linux, and Android, and covers a wide range of media types: retro games, movies, TV shows, animation, anime, manga, visual novels, and books.

The core idea is unified collection management. You can mix any media type into a single collection, switch between grid and list views, and track status across four states: In Progress, Completed, Planned, or Dropped. For TV shows and anime, it tracks individual episodes. Everything can be rated on a 1–10 scale with personal notes attached.

Finding titles is backed by a broad set of databases:

• Games: IGDB, RetroAchievements, SteamGridDB
• Movies and TV: TMDB, Kinorium
• Anime and manga: AniList, MangaBaka, MyAnimeList
• Visual novels: VNDB
• Books and comics: OpenLibrary, Fantlab, Google Books, ComicVine

Beyond basic tracking, it has a few features that set it apart from a simple TV time alternative. Visual Boards let you arrange posters on a free-form canvas, add text notes and links, and draw connections between items. Tier Lists support drag-and-drop ranking into S/A/B/C tiers, and a Mood Grid lets you lay out picks on a customizable N×M board. Both export as PNG.

Importing existing data is well-covered. You can pull in libraries from Steam, Trakt.tv, RetroAchievements, MyAnimeList, AniList, and Kinorium. Sharing works through two export formats: a lightweight .xcoll file (requires internet for images) and a self-contained .xcollx package that works fully offline. Friends can import and fork your lists directly.

The app is built with Flutter and uses SQLite locally, so your data stays on your device. No account required, no cloud dependency. API keys for IGDB, TMDB, and SteamGridDB are optional; the app works without them out of the box.
