How hard is this book, and how long will it take you? Every book in ReadingRate carries nine measured difficulty scores, each with a written reason, and a word count turned into hours at your reading speed. Look anything up before you commit a month of evenings to it. No account needed. FREE, FOREVER, NO CARD Import your reading history from Goodreads, StoryGraph, Readwise or Notion. Log every reading day, in the app, by Siri, or by telling ChatGPT or Claude. Keep your library, your journal and your quotes. Read difficulty scores and reading-time estimates on every book. Export all of it whenever you want. Nothing here runs out after a week. NINE MEASURED DIMENSIONS Four for how hard the prose is to parse: vocabulary complexity, syntactic complexity, abstraction level, information density. Five for how hard the meaning is to reach: narrative indirection, symbolic density, ironic distance, resolution withholding, structural complexity. Each one scored 0 to 100 for that specific book, each with a written reason. YOU READ THE BOOK WHEREVER YOU READ BOOKS Paper, Kindle, library copy, audiobook. ReadingRate is not where you read. It is where the reading is kept: what you finished, how long it took, and the lines you marked. LOGGING TAKES ONE TAP Tap the book and the page you reached. Or tell Siri. Or say it to ChatGPT or Claude and it lands here. No timer, and nothing to fill in while you are trying to read. YOUR READING JOURNAL Capture thoughts and connections as you read. Save a passage and it is anchored to its page for citation later. Build a record of your relationship with a book, for reviews, essays, or just remembering why it mattered. BARCODE AND SHELF SCANNING Add a book by scanning its barcode. Members can photograph a whole bookshelf and have it read the spines. APPLE WATCH AND WIDGETS Log pages and check progress from your wrist. Currently reading and reading pace on your home and lock screens. BROWSE AND DISCOVER Curated lists, prize winners, and thousands of books with full difficulty analysis. Free to explore without an account. WHAT A MEMBERSHIP ADDS Deep analysis of any book, the Insight Lab, the full Eras atlas and literary map, book clubs, thirty shelf scans a day, the WhatsApp bot, and asking Claude or ChatGPT about your own reading history. Putting your reading in is always free. A membership is for getting more back out.

Verdict

The call

ReadingRate and Book are too close to call on the numbers: across 6 compared parameters — price, ads, in-app purchases and monetization model among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. ReadingRate sells 3 in-app purchases, starting at $9.99 per month and Book sells 5 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
