Leja

How many times have you bought a book you already owned, or been unable to remember which shelf held that movie or game? If your solution until now has been an Excel spreadsheet, relax: that's over. Leja manages your collection without a single cell in between.

And it's not just books: Leja can hold everything that takes up a shelf. Books, movies, music, video games, and board games—each item with its own entry and in its place.

Organize your collection exactly as it is: on bookshelves, individual shelves, tables, stacks, or carts. Each location represents a distinct space within your home.

Add books in seconds by scanning the barcode: Leja fills in the title, author, cover, genre, and other information. For music, movies, video games, and board games, simply search for them by name. If something isn't listed, fill it in manually and add your own photos of the cover and spine.

What makes Leja special is its virtual shelving unit, which you customize to your liking (shelf type, number of shelves, dimensions, color) to resemble your own. Place everything exactly where it is in your home—standing, lying down, or with the cover facing you—even in multiple rows, one behind the other. Each item occupies its actual space, so the virtual shelving unit fills up at the same rate as your real one.

Can't remember where you put it? Search for it by title, author, genre, or rating throughout your entire house at once, and Leja will point it to you on its shelf, making it shine.

Mark what you've already read, watched, or played, rate it, and create your own categories. It also keeps track of loans in both directions: who you've lent what to and what you've borrowed, along with the return date, so you never lose or forget anything.

Leja is completely free and respects your privacy: no accounts, no ads, and no trackers. Your collection and photos are saved only on your phone, and it works offline. Export a backup whenever you want so you never lose anything.

If you'd like, you can help improve Leja's book catalog by anonymously contributing missing data (such as a book's dimensions). The app will show you what it would send beforehand and ask for your permission.
