좋아요

제가 독서 기록앱 진짜 많이 써보고 직접 만들어서도 써보다가 딱 만족스러운 게 없어서 늘 헤매다가 이 앱으로 정착한지 1년이 더 지났네요. 깔끔하고 독서 기록이라는 목적에 충실하고 다른 부가 기능들도 너무너무 좋아요. 근데 처음 이 앱을 쓰기 시작할 땐 이 정도는 아니었는데 지금은 광고가 너무 많이 나와요… 예를 들면 전엔 책 읽기 종료하면 코인 두배 받기를 눌러야만 광고를 보는 거였는데 지금은 일단 종료 누르면 광고 나오고 빨리 끝나는 광고도 아니고 30초 정도는 광고 화면에 잡혀있다가 코인2배 눌러서 광고를 또 봐야해요. 전에는 책도 읽고 코인도 모아서 아이템들 하나씩 사는 뿌듯함도 있고 귀여운 고양이 꾸미면서 기분도 좋았는데 요즘은 그냥 안 하게 되네요. 독서 기록을 한다는 본질이 좀 흐려지는 느낌이어서 아쉬워요.

超オススメ!

読書記録を付けたくて、YouTubeなどでレビューを見まくった結果一度某アプリに辿り着いたのですが、結局めんどくさくて放置してました💧たまたまインスタの広告で見かけてこちらをダウンロードしてみたんですが、めちゃくちゃ良いです!
使いやすい&欲しい機能がほぼ揃っている&可愛い&治安が良い!笑。他SNSのように無駄な交流機能(コメントやメッセージなど)が無くお友達追加機能のみなので、好みが近い人を安全に見付けられて凄く平和です☺️✨
一緒に読書してくれる猫も可愛い🐈‍⬛✨超超超オススメです👍🏾

매일 조금씩이라도 읽는 습관이 들어요

책을 하루 왕창 읽고 한동안 쳐다도 안 보다가 또 왕창or찔끔 읽고 이런 식이었는데 고양이 책집사를 활용한 이후부터는 매일매일 책을 읽는 습관이 자연스럽게 들었어요. 게임 속 일일퀘스트 진행하는 느낌이라 재미있습니다. 원래 금방 싫증이 나서 뭐든 진득하지 못한 편인데 이 앱은 1년 넘게 쓰고 있어요! 정말 추천합니다.

素敵なアプリです。もう少しだけ改善して欲しいです。

読書に必要な機能が一通り揃っている、とても素敵なアプリです。
ねこちゃんも可愛く、着せ替えも楽しめるので、癒されながら読書を楽しんでいます。

とても気に入っているアプリだからこそ、「こうだったらもっといいのにな」と感じる点がいくつかあったため、以下に記載させていただきます。よろしければ、改善をご検討いただけますと幸いです。

・本棚のフォルダ分け機能
本棚の本をフォルダごとに分類・整理できるようにしていただきたいです。ジャンルや目的に応じて本をまとめられると、より使いやすくなると思います。

・読書記録のグラフの改善
記録画面の「読書時間」と「読んだページ」のグラフをひとつに統合していただけるとうれしいです。ひとつのグラフ上で両方の記録を確認できる形式や、表示する項目を切り替えられる形式が理想です。難しい場合は、「読んだページ」を折れ線グラフで表示するだけでも変化が把握しやすくなると思います。

・大サイズのウィジェットの棒グラフの改善
大サイズのウィジェットに表示される棒グラフについて、棒同士の間隔を少し広げていただけると、より見やすくなると思います。

素敵なアプリを開発・運営してくださり、ありがとうございます。本当に便利で素敵なアプリで、出会えたことに感謝しています。これからも愛用させていただきます。

求めてたアプリ!感動した!

本好きで記録したいけど、時間もないし、ノートに書くのが苦手…。外で読むこともあるし…。と思ってました。それを手軽にしてくれて尚且つかわいい!一緒に読んでくれるので、少しの時間でも読もうかな、と思えます。自習室の方も一緒に使ってて、使い分けしています🐱

ただ、読みたい本からの「読む」押さずに(時間を計測しないまま)読書終了にすると、読み終わった日の変更ができないことが残念です。。(読書記録を編集、では読んだ時間のみ変更可能💦)読んでも、その日に必ずしも記録できる訳ではないので、良かったら日付も変更できるようにしていただけると助かります。

あとは友達と読んだ感想とか共有できたら嬉しいです!せっかくフレンド機能があるので、読書仲間(グループ)と共有できるのがあればと思います!
