What it does

Built for people who actually own a lot of books.

Six features that turn a shelf-full into a system. No subscriptions, no nonsense.

ISBN Barcode Scanning

Point your phone at the back of any book. Booklgy looks up the title, author, and cover instantly — no typing.

Household Sharing

Invite your partner, roommate, or whole family. Everyone sees the same library, in real time.

Read / Unread Tracking

A single tap marks a book as read. Filter your library to find what's still on the to-read pile.

Multi-Owner Tagging

Track who owns what. Tag a book to one person, both of you, or the household — useful when a relationship ends a bookshelf doesn't.

Smart Search & Filter

Author A–Z, by genre, by series, by owner, by read status. Find any book in seconds — even when your shelf has hundreds.

Your Data, Yours

Export your full library to CSV. Back up the database. Take it with you whenever you want — no lock-in.

How it works

Three steps. That's it.

Get your whole shelf in your pocket in an afternoon.

i

Scan your shelf

Open the camera, aim at each book's barcode, and Booklgy does the rest. About 10 seconds per book once you find a rhythm.

ii

Invite your household

Generate an invite code in Settings. Anyone who joins sees the same library and can add their own books to it.

iii

Never re-buy again

At the bookstore, search by author or title before you check out. The little gold dot tells you if you've already read it.

"It started as a way to stop buying The Handmaid's Tale a third time."

Booklgy is built for households that actually live with their books — couples merging libraries, families with overlapping taste, anyone whose to-read pile has gotten away from them.

A peek inside

Designed for readers, not collectors.

Every screen is built around the moment that actually matters: standing in a bookstore wondering if you already own this one.

Questions

Everything you'd want to ask.

Is Booklgy free?

Yes — the core app is free on the App Store. We may add an optional pro tier later for power features, but household sharing, scanning, and unlimited books will always be free.

How does household sharing work?

One person creates the household and generates an invite code. Anyone with the code joins the same shared library — books, owners, and read status all sync between devices.

What if a book isn't found by ISBN?

You can add it manually in a few seconds — title, author, format, genre, owner. Booklgy doesn't lock you into the lookup.

Can I export my library?

Yes. Settings → Data → Export CSV gives you a clean spreadsheet. You can also back up the entire database. Your books, your data, no lock-in.

Is there an Android version?

Not yet. iPhone first — Android is on the roadmap. Drop your email below and we'll let you know when it's ready.

Does it work offline?

Adding, browsing, and editing all work offline. Your changes sync to your household when you're back online.

Stop buying the same book
twice.
