### 5/5 — 還行

*2025-10-16*

帳號預設為身分證字號，密碼預設為生日。

### 1/5 — Does not work

*2022-02-17*

Unable to read because the download keeps failing. Please fix.

### 4/5 — 便利借書閱讀，但還可以更好

*2021-12-19*

我試用約三四週，整理體驗還不錯，可以連結各公共圖書館借閱電子書是我看重它的主要原因，雖說主要前往的台北市圖可借閱的數量還不算多，但對我這種閱讀慢的人來說也算足夠。

唯一一點困擾我的，是app沒有提供跨平台儲存閱讀進度的功能，我經常在手機和平板間切換，而且平台一旦切換，帳號也會同步登出，每回都要重新登入、重新找出前次閱讀的暫停點，實在很累人。

反觀其他閱讀程式都有這樣設計，例如Kindo、iOS iBooks、Readmoo等等，這功能可能跟調整閱讀字型大小、翻頁模式一樣重要。

### 1/5 — 非常爛

*2019-07-02*

使用軟體無法登入，用瀏覽器登入後找不到要借的書，用作者搜尋也是
