Reading calendar month view with cover art

A calendar of what you were reading.

Log a reading session — the book, how long, a note if you want. The month view fills in with cover art on the days you read.

Look back at any day and see what was open in your lap. A journal you build without meaning to.

Reading calendar with cover art on read days

Never buy the same book twice.

Every book you scan carries an ownership state — Own, Want, or Read. Scan a book at the store and the app tells you, calmly, whether you already own it.

Sharing a library with your spouse? The check spans every library you have access to. No more standing in the aisle, unsure.

Book detail with Own, Want, Read chips

Built the way readers keep books.

Small, thoughtful pieces that add up to a library you actually enjoy tending.

i.

Scan & remember

Point the camera at a barcode. Or type an ISBN. Or snap a photo of a shelf and let the app read the spines. Title, author, cover — filled in for you.

ii.

Own · Want · Read

Every book carries a state. Physical or ebook, and if ebook, which store — Kindle, Apple Books, Kobo. Filter your grid by any of them.

iii.

A reading calendar

Log each session with a note if you feel like it. The Month view shows cover art on the days you read. Journal tab keeps every note, most recent first.

iv.

Custom shelves

Favorites, To Be Read, Signed Editions, Kids Books — whatever you want. A book can sit on more than one. Rename or remove any time.

v.

Shared libraries

Every person owns their own library. Make one for your spouse, your kids, a work collection. Share the ones you want to share. Nothing is shared by default.

vi.

Bring your history

Import from Goodreads, StoryGraph, BookBuddy, or LibraryThing via CSV. Or point the camera at a screenshot of any book list and let the app read the titles.

vii.

Yours to export

Your data belongs to you. Export the whole library or your reading log to CSV any time. Take it to Numbers, Excel, wherever you want.

viii.

Library value

Optional running total of the estimated retail value of the physical books you own. Useful for insurance, curiosity, or just seeing what you've built.

ix.

iCloud sync

Books scanned on your phone appear on your iPad. No accounts of ours, no servers of ours — your data lives in your own iCloud private database.

A library for each person you love.

Make one for yourself. One for your spouse, one for each kid, one for the shelf at your desk. Pick a kind, name it, done.

Share the libraries you want to share. Keep the ones you don't want shared entirely private. The duplicate check quietly looks across every library you have access to.

No servers of ours.

Your books, notes, and reading log live on your device and sync through your own iCloud private database. We can't see any of it.

No analytics. No ads.

The app doesn't track what you read, what you tap, or when you open it. There is no advertising network attached. Ever.

Yours to leave.
