Hey PH! 👋 I built Tonkatsu Box because I got tired of having separate apps for tracking games (Backloggery), movies (Letterboxd), anime (MyAnimeList), and visual novels (VNDB). None of them talked to each other, and I couldn’t build mixed collections like “best sci-fi across all media” or “things I enjoyed in 2025.” So I built one app that connects to all the major databases and lets me organize everything in one place. A few things I’m particularly proud of: The canvas mode — you can drag posters onto a free-form board, add notes, and draw connections. I use it to map out franchise timelines and “if you liked X, try Y” chains. No account required — everything is local SQLite. Your data is yours. Export it as a .xcollx file anytime. Retro game support — 170+ platforms in IGDB means you can catalog your entire collection from Atari to Switch. The app is fully open-source (MIT license) and I’m actively developing it. Manga support via AniList is coming in the next release. Would love to hear your feedback and suggestions! What media type or feature would you want to see next?
