Citrus Shelf

Give the books you read a place of their own.

Citrus Shelf is a reading log that grows into a bookshelf. Each book has a spine shaped by its page count and coloured by its genre. Books in progress begin in linen; as you read, their colour rises. Finished books gather into a shelf worth looking back at and sharing.

Add a book by searching for its title or author, scanning its barcode, or entering the details yourself. Check the page count, choose Reading or Finished, and give it a place on your shelf. Filter by Reading or Finished, or search your library by title or author.

Make the room yours. Choose Light or Dark appearance and one of six accent colours, turn favourite books face out, and arrange a plant, a cat or puppy, a reading lamp, a tea mug, a candle and more on the boards, each made in 3D and brought to life when you tap it. Create collections for comfort reads, books that changed you, or any story your library tells.

Keep the words that stay with you. Write thoughts, quotes and photos in a book’s margins, with an optional page number. For a quiet reading session, choose a time target and, if you like, a sound, from soft rain to ocean waves, that keeps playing with your phone locked, then record your progress when you finish.

Look back at finished books on your shelf this month, this year and all time. See the pages in books you finished this year, your longest and shortest finished books, a January-to-December view of this year's finishes, your progress towards a yearly goal you choose, and the genres you've read.

When you want to share, make a picture of your shelf, a collection, a book, a margin note or a monthly or yearly recap. Choose a square, portrait or story format, save it to Photos, or open your phone's share sheet. Notes and photos appear only in images you choose to include them in; a book’s notes are off by default. Shelf, collection and recap images never include them.

Your library works on your phone without an account or a connection. Searching the catalogue or looking up a barcode needs a connection. Sign in when you want to keep your shelf across phones. Thoughts and quotes travel with it; photos in your margins do not sync between phones.

Start with the book you are reading now. Let the shelf grow from there.
