This has been the only thing that has actually gotten me back into reading. I love how visual everything is - especially the calendar and the stat wheel. And of course I love dressing up my cat. I have been showing it to all my reader friends. Definitely worth checking it out! ### 4/5 — 良いアプリ *2026-08-14* 読書ノートを書こうと思ったけど、こちらのアプリを見つけて試しに入れてみたら使いやすいし、猫可愛いので、ノートまで買ったのにやめました。 たまに本の画像が出ないので自分で入れないといけないのが面倒かな。 アップデートが多いけど、もっとこのアプリ使うのが楽しくなってよい。 オーディオブックも記録できるけど、聞いたのを記録するには微妙な気がする。聞いたタイトルだけ記録なら良いかな。 途中でやめた本も記録出来るようになったの良い。どうしても読み進められない本とかたまに出てくるので。 今のところ紙の本だけで記録してるけど、本の媒体ごとに表示できたら便利そう。 きりがないけど自分的に読んで手放した本もカテゴリで分類できたら良いな…と。持ってる本の管理も兼ねてるので。 ### 5/5 — アイコンが可愛くて好き *2026-08-14* 猫のアイコンがシンプルなのに可愛くて開きたくなります。 読書記録が本棚に並んでいるのを見て気持ちが上がります！ これからの読書時間も共にしていきたいです。 ### 5/5 — 読書時間が楽しくなるアプリ *2026-07-25* ネコがかわいくて、使うほどに愛着が湧いてきます。 読書アプリに欲しい機能がほぼ全て備わっており、遊び心も散りばめられていて、かわいいだけでないところが本当にすばらしいです。 欲を言えば、収集した文章をランダム表示で見返すことができたらありがたいなと思いますが、今のままでもとても気に入っています。 何よりこのアプリのおかげで、今まで以上に読書が楽しくなりました！ ### 5/5 — シンプルだがそれがいい *2026-07-14* 読書アプリとして求めていたものがここにあった。シンプルでわかりやすく読書管理アプリとして使いやすい。読書習慣をつけようとしてる人におすすめです。買い切りプランがあるのも評価が高い。今後、更なる機能追加もあるだろうが、シンプルで使いやすいアプリのままでいて欲しい。 追記、読書中の画面で現在時刻が表示されるといいかなと思いました。 2026.7/14追記 アカウント名が『本執事』から変更はできないのでしょうか？ **Developer response:** 最高の褒め言葉をありがとうございます！🐾 「シンプルで使いやすい」という点は、私たちが最も大切にしている部分です。今後機能を追加していく際も、今の使いやすさを損なわないよう十分に配慮して開発を続けてまいります。買い切りプランもご活用いただき、大変光栄です。 これからも、私たちの猫と一緒に素敵な読書習慣を続けてください！✨ ### 3/5 — 可愛いんだけど… *2026-07-12* 可愛くて使いやすいんだけど、アップデートが多い。頻回すぎて面倒。このままの回数が続くならやめよかなって思う。 ### 3/5 — App is not working *2026-07-09* I LOVE this app with every fiber of my being. This helps me keep track of my reading log after I’ve been struggling for the past few weeks. The reason why my review is low, however, is that the app suddenly stopped working on me, constantly hitting me with the “No Internet Connection” bug. My app is updated all the way, my phone was restarted, and the app was even deleted and redownloaded to clear out the cache, but it still won’t work. This bug confuses me too because it was NEVER an issue in the area I’m in. I’m worried that all of my data has gotten lost while trying to fix it and there’s no email to contact for issues like these. Please, if there are any updates on this fix, do it ASAP. **Developer response:** Hi! Thank you so much for loving Cat's Library and for taking the time to write such a detailed review. I am truly sorry for the late response and for the inconvenience and frustration caused by this "No Internet Connection" issue. Please rest assured that your reading data is safe on our servers. To help us investigate and resolve this specific issue for your account right away, could you please email us at contact@catslibrary.com with your account details? We will look into this as a top priority and get back to you with an update ASAP. Thank you for your patience and support! 🐾 ### 5/5 — 행복 *2026-07-06* 기본적인 기능이 다 있고 누구나 원할 기능들 사용하기 편하게 구성되어있어요! 또 고양이를 꾸미다 보면 스트릭 채우기 위해서 더 독서를 열심히 하게 됩니다😊 지금까지 여러 어플 많이 찾아다녔는데 이제야 정착했어요. 다른분들에게도 많이 추천하고 다닙니다! **Developer response:** 안녕하세요 책집사님, 소중한 리뷰 진심으로 감사드립니다! 귀여운 디자인과 편한 UI 좋아해주셔서 감사합니다. 말씀해주신 "문장 수집 텍스트 입력"과 "분야별 폴더 정리" 기능 검토하여 더 나은 서비스로 보답하겠습니다! 👩🏻‍💻 🐈 좋은 하루 보내세요! =^_^= ## Frequently asked questions about Cat's Library ### Does Cat's Library have ads?
