Your whole collection. Not one hobby at a time.

Collectors rarely collect one thing

Look at the app stores and every collection tracker is single-hobby: a Pokémon card scanner, a Magic deck manager, a vinyl cataloguer. Which is fine until you collect two of those — at which point you are maintaining two databases, two backup routines and two mental models, for what is really one shelf.

Stadu keeps the categories separate where the data genuinely differs, and together where it does not.

What it tracks, and where the data comes from

• Pokémon TCG — searched against the Pokémon TCG API, so sets and card art come in correctly.
• Magic: The Gathering — backed by Scryfall, the reference card database.
• Vinyl and music — via Discogs, with a one-tap import of your existing Discogs collection.
• Games — IGDB-backed, plus your Steam library in one tap.
• Books — Open Library.
• Anything else — sneakers, LEGO, stamps, figures: a custom category, because no app can ship a bespoke API per hobby and pretending otherwise just creates dead ends.

Owned and wishlist, side by side

Every item is either owned or wishlist, so the thing you are hunting for and the thing on your shelf live in one list rather than in two apps. When you finally get it, moving it across is one tap.

Owning something and having experienced it stay separate on purpose: a game you own is not a game you played, and a record you bought is not a gig you went to. Stadu keeps both records and lets them know about each other.

Offline, and not a marketplace

Stadu does not sell anything and does not want your collection on a server. There is no account, nothing is uploaded, and the whole collection exports to a backup file you own. It is a catalogue, not a storefront.
