TrackBrowser

■ Overview ■ TrackBrowser is an unofficial app for browsing and managing IIDX song lists. Powerful search, filter, and sort tools help you find songs and explore difficulty charts and version-specific data.

Import an arcade score CSV or a CSV from a third-party tool compatible with INFINITAS to add scores and clear lamps to the song list. You can also review update history, performance trends, and Player Notes Radar (PNR). No CSV is required—you can use TrackBrowser purely as a song browser. Song data is maintained on a best-effort basis, with automatic update attempts at launch.

■ Important Notes ■ 　- This is an unofficial app for the beatmania IIDX series. 　- Displayed data is compiled from public information and score CSV files imported by users. 　- Imported CSV files themselves and user-entered memos are never uploaded to a server. 　- Only when you choose Score Sharing, shared score details are encrypted and stored in your own PDS. Metadata such as Share ID, display name, publication status, PNR, entry count, and update time is stored in a search database. 　- Shared data is technically associated with the Bluesky account used. 　- The app does not access the game, the official IIDX website, or official game servers.
