読み終えた本が、喫茶店の机の上に積み上がっていきます。 太さは、その本のページ数のぶんだけ。冊数ではなく「高さ」で、読んだ量が見えるアプリです。 積んだ高さは、1円玉から松本城の天守まで、46の身近な物とくらべられます。 高さがのびると、小さななかまが1体ずつ目をさまします。 さいしょの1体は、文庫1冊ぶんの高さで。 【できること】 ・本の登録: タイトルで探して2タップ。手入力でも登録できます ・積みタワー: 読み終えた本が、ページ数ぶんの太さで積み上がります。2本の指でひろげると、うすい本の題名も読めます ・身近な物とくらべる: 塔が越えた物を、同じ縮尺で並べて見せます。越えた瞬間には、どれだけ高くなったかも出ます ・みちのり: その年に越えた物と、越えた日・何冊目かが残ります。12月と1月は1年ぶんを1枚の画像にできます ・なかま図鑑: 積んだ高さで、8体のなかまが順番に目をさまします ・本棚: 読んだ本の表紙が、月ごとの木の棚にならびます ・読みグセのグラフ: 月ごとの冊数、気分、読む速さの内訳が見えます ・ブクログからの取り込み: これまでの記録をCSVでまとめて積めます ・共有: タワーの画像を書き出せます。越えた物と並べた画像にもできます。本の題名を見せるかどうかは選べます 【高さについて】 ・高さはページ数から計算した、おおよその目安です。実物の厚みとは少しちがいます ・ページ数は書誌データベースから自動で入ります。手で直すこともできます 【データについて】 ・記録はすべて端末の中だけに保存されます。アカウント登録は不要です ・本の検索と取り込みのときだけ、検索語と本の ISBN が送られます。最初に一度だけ聞く「このアプリをどこで知ったか」の答えも送られます(くわしくはプライバシーポリシー) 【こんな人に】 ・「今年は何冊」より「今年はこれだけ読んだ」を目で見たい ・電子書籍や図書館の本ばかりで、読んだ痕跡が手元に残らない ・静かに、ひとりで、積み上がっていくのを眺めたい 【リンク】 ・プライバシーポリシー: https://yomidana.vercel.app/privacy/ ・利用規約: https://yomidana.vercel.app/terms/

A reading tracker that makes adding books easy — and stacks up every book you finish. ADDING A BOOK IS ONE SCAN Point the camera at the barcode (ISBN) on the back of a book and the title, author, cover and page count are filled in. Scans run back to back, so a whole shelf takes a couple of minutes. You can also search by title or author and add a book from the results. WHAT YOU READ BECOMES HEIGHT The page count of each book turns into thickness, and your finished books pile up. Look back on how tall your stack has grown. A mug, an ostrich, a utility pole — your stack is drawn next to things you know, so you can see how far it has come. You can also turn the stack into an image and share it. YOUR TBR PILE AND YOUR READS, SORTED Five statuses keep your books sorted: Wishlist, TBR, Reading, Read and Paused. Books you're curious about go to Wishlist; books you own but haven't read yet go to TBR. Move them to Reading when you start, Read when you finish, or Paused if you set them aside. You can also see how tall your TBR pile alone has grown. Finished books can hold a star rating, the date you finished, and a note about what you thought. Add tags and you can filter later by "fiction", "work", or anything else you use. RE-READS COUNT TOO When you read a book again, each read gets its own finish date and notes. EVERYTHING STAYS ON YOUR DEVICE Titles, notes, ratings and the cover photos you take are kept on your device, not on a server. There is no account and nothing to log in to. When you change phones, export a backup and import it on the new one. LOOK BACK ON YOUR READING Built-in reading stats. Books read, pages read and the height of your stack, whenever you want to see them. See how much you read by author or by tag. WHO IT IS FOR - Readers whose TBR pile got out of hand - Anyone who wants to count books and pages, not just titles - Readers who want to keep notes instead of a separate reading journal - Fiction, non-fiction and comics, tracked in one place - Anyone looking for a book tracker that works without an account FREE, WITH NO BANNER OR FULL-SCREEN ADS Every feature is free. No banner or full-screen ads, and no in-app purchases. ALSO - English and Japanese, following your device language - Stack height in cm/m or inches/feet, whichever you prefer - Works offline; only book search needs a connection
