About

You underline as you read. Then the lines stay in the book, because typing one out is more work than it is worth in the moment. Underlined is a reading tracker built around getting them out. Photograph the page, draw a box round the passage, and it is yours. A PASSAGE WITHOUT TYPING IT • Photograph the page and draw a box round what you underlined. Nothing is retyped. • The box is coarse on purpose: it only has to contain the passage. The words are trimmed back to whole sentences, so a box that clips a few still gives a clean quotation. • The page number is read off the photograph, so keeping a line from page 214 moves your reading progress to 214. When it cannot be read, the app asks. • Text read off a page is never quietly corrected. A word that looks wrong is offered as a suggestion — against word lists carried on the phone, in twenty-six languages — and nothing changes until you say so. • Star the ones that matter. Add a thought underneath while it is still fresh. A SHELF IN ONE PHOTOGRAPH • Point the camera at a row of spines instead of typing forty titles. • Books standing up, books lying flat, a shelf shot at an angle, all without turning the picture. • A single cover works too, for the book in your hand. • Everything found is shown to you first. You choose which go on the shelf and which shelf. YOUR READING YEAR • One goal for the year, paced against how far into the year it actually is — not against a flat count. • Three shelves and no ceremony: want to read, reading, finished. Your TBR is just a shelf. • Keep the page you are on; the last page finishes the book on its own. • Write down how a book left you, in a sentence or two. • Statistics about reading, not about scores: passages kept this month, this year and all time; how many you starred; how long they run; books finished, by year. WHAT YOU KEEP COMES BACK • A passage resurfaces each day, from your own collection. • Search every line you ever kept, with your words marked where they were found. • The ones you return to rise: the app counts which passages you come back to. • Dig into a passage with a model that runs on your phone, never a server. (Recent iPhones.) • Read a passage in another language through Apple's own translation sheet. DISCOVER • Passages other readers underlined, narrowed by subject, in the languages you read. • Keep the ones that stay with you; they join your own shelf. • Find the book behind a line: what it is about, more by the author, books shelved beside it, and where to buy a copy. • Offer a passage of your own if you like — a button you press, never something the app does on its own. Anything can be reported and taken down. TAKE IT WITH YOU • Send a passage as a picture, set as a page rather than a screenshot. • Export one book's passages, or everything you have ever kept, as a PDF set at paperback size. YOUR LIBRARY STAYS YOURS • No account. Nothing to sign up for and nothing to sign in to. • Your books, your progress and your passages live on your phone. • The app does not upload your notes and it does not track you. • Eight languages in the app itself, and passages in twenty-six. • A colour for every book; paper by day, ink by night. FREE AND PRO Five books, free, with every feature working — the camera included. Keeping passages is free without limit and always will be: it is what the app is for. Underlined Pro opens the shelf to as many books as you keep. SUBSCRIPTION Underlined Pro is an auto-renewing subscription: $2.99 a month, or $19.99 a year.
