Your books, on a shelf. Track every book you read or listen to, plan your TBR, and watch your reading year fill in. Booktrace works for print books, ebooks and audiobooks. Add a book, say what format it is, and start a session. For a paperback or an ebook you say which page you're on and Booktrace counts the pages down; an audiobook moves forward by the minutes you listened. Booktrace keeps the time either way. YOUR BOOKSHELF Take one photo of a row on your real shelf and every spine stands on a shelf inside the app, or scan books one at a time. Lean them, stack them, drag them into place, and add a plant, a lamp, or a photo. A bookshelf that looks like yours, because it is. YOUR TBR, SORTED Flip through your want-to-read pile like a crate of records, or let Pick one choose your next book when you can't decide. Browse your whole collection as a wall of covers, and see your history as…
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 6 screenshots above are Booktrace: Bookshelf & TBR's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Booktrace: Bookshelf & TBR runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #1C1C1C) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #0C6474, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
