Make reading a daily habit, and remember the books you've read. Reading Memory keeps every book you read and every line you write, one book at a time, on your own bookshelf. You want to read more, but it never sticks. You finish a book, then can't recall what was in it. The books you bought sit on a pile, unread. Reading Memory is made for that. MAKE READING A DAILY HABIT On days you read, tap "Read today" once. Even a day with one page counts. Your reading days fill a calendar, and your streak and the number of books you finished this year go up. You can also tap from Home Screen and Lock Screen widgets. NEVER FORGET WHAT YOU READ Notes you write while reading show up on your bookshelf a few days later, with how long ago you wrote them ("written 72 days ago"). Read them again and add a line right there. When you reread a book, the notes from your last read are on that book's page. FINISH YOUR TO-READ PILE, ONE BOOK AT A TIME Books you own but haven't started sit in a pile at the bottom of your bookshelf. Tap the pile to start the top book. When you finish one, the app picks the next book from your pile. PRIVATE BY DESIGN No social feed, no followers, no public reviews. Only you can read what you write. — WHAT YOU CAN DO ◆ Bookshelf Finished books stand on a shelf for each year. Books you're reading lie face up, and books you haven't started are stacked. You can also add the books you've already read, one after another. ◆ Add books Search by title or scan the barcode. Book data comes from Google Books, Open Library, openBD, and Rakuten Books. There is no limit on how many books you can add. ◆ Sticky notes for novels Write about characters, lines you loved, and how you felt on sticky notes, and stick them at the page you're on. Move the bookmark to record your page and "Read today". ◆ A notebook for nonfiction Write the book's words and your own thoughts with page numbers. Snap a page to read its text and add the lines you pick as the book's words. Vertical Japanese text works too. Export your notebook as text. ◆ A reading card when you finish Give stars, write one line, and stamp the card. It goes into that year's card box. Save or send the card as an image. ◆ Reading log and badges See your reading days on a calendar, your streak, and how many books you finished. Earn badges at milestones. ◆ Want-to-read list Note who recommended a book or where you saw it. ◆ iPad Works on iPad, in portrait, landscape, and Split View. — MEMORY PLUS (auto-renewable subscription) Adding books, sticky notes, notebooks, reading text from pages, reading cards and stamps, the calendar, and widgets are free for good. Memory Plus adds: ◆ Turn the lines you picked from a page into key points (uses AI) ◆ Look up a word from your notebook across all your books (free shows the number of books and the first line) ◆ Your year in books: everything you read and wrote in a year, in one place ◆ Detailed statistics: books finished per month, genres, ratings, and how books made you feel ◆ Summaries of the notes you wrote (uses AI) Pricing in the US: $39.99 per year / $3.99 per month. Prices vary by region. Payment is charged to your Apple ID at confirmation of purchase.

Verdict
The clearest difference is update cadence: Honyomu at every 3 days against Reading Memory's every 2 months. Honyomu also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
