Collectary is a cross-platform app for cataloguing the things you collect — books, coins, board games, sneakers, houseplants, trading cards, whatever you track. Define each collection with typed fields, add items, and optionally share and sync your data across devices.
It's built with .NET and Avalonia, runs on Windows and Android, and compiles to WebAssembly to run in a browser tab.

- Custom collections — start from 20+ built-in templates (Books, Coins, Board Games, Sneakers, Wine, Video Games, …) or design your own.
- 22 field types — text, rich text, numbers, currency, dates, durations, ratings, colours, images, tags, single/multi choice, and more.
- Profiles — switch between profiles from a row of tiles; no passwords, just a name.
- Sharing & sync — grant other profiles read/write access, and keep collections in step across devices through a shared folder with conflict resolution.
- Themes & languages — light/dark themes and an English/German UI.
