### 5/5 — すごくgoo‼️

*2025-12-01*

使いやすい、月毎に背景を変えられるので月別がすぐにわかる。
今までの日記帳アプリでは一番気に入っている。

**Developer response:** レビュー ありがとうございます。
気に入っていただけて光栄です。

### 4/5 — Excellent app!

*2025-11-27, version 1.8.0*

I very much like this app and wanted to give it 5 stars but you cant delete photos in it.

### 5/5 — 🐱😂

いいね！

**Developer response:** レビュー ありがとうございます。
気に入っていただけて光栄です。

### 4/5 — 感想と要望

*2025-06-28*

シンプルで分かり易く、私の使い方にあっています！ 要望1. アプリ独自のパスコードを設定できると大変有り難いです。現状、iphoneのパスコードと同じなので、iphoneに入られるとアプリも開けることになってしまいます。 要望2. ダークモードがあれば嬉しいです。要望1よりは弱めの要望になります。 ご検討頂けると幸いです。よろしくお願いします。

**Developer response:** レビューありがとうございます。
ご要望について検討致します。

### 5/5 — Достойная работа. Спасибо разработчику.

*2025-02-06*

Но очень плохо, что отсутствует возможность синхронизации между нашими устройствами. И это не есть хорошо!

**Developer response:** Спасибо за ваш отзыв.
Мы рассмотрим Вашу просьбу.

### 5/5 — Очень хорошая работа, спасибо.

*2024-10-18*

Но! Не могу порекомендовать эту программу друзьям, потому что она ограничена только одним устройством. То есть она намертво замкнута только на одном устройстве. Она без синхронизации. Она не может быть на моём телефоне и на моём планшете. Это не есть хорошо. И что вот с этим делать, что скажете. Отсутствие синхронизации сужает использование такой толковой разработки. Это так печально! Успехов✊Вам разных и много. Спасибо.
   Вы уже рассмотрели пожелания? И каков результат? Не будет работать на двух устройствах? Это как птица без крыла и песня без души...

**Developer response:** Большое спасибо за обзор.
Я рассмотрю вашу просьбу.

### 5/5 — 增添一键导出功能

*2024-10-15, version 1.5.0*

希望增添一键导出全年日记功能

### 5/5 — 天才的な日記様😊

*2024-06-06*

まず、今まで使ってきたやつで1番いいし、なんか、言葉にできないくらいめぢゃいい( ` -´ )bｲｲﾈｯ✨絶対入れて！

**Developer response:** レビュー ありがとうございます。
気に入っていただけて光栄です。

### 3/5 — 不負責任評論

*2024-03-29, version 1.4.4*

優：
時間軸配日曆增加選擇彈性

缺
一、無法利用icloud，各項設備無法互通（偏偏果粉每人的蘋果都不只一顆）。每項設備都買個幾美元也不算什麼，但設備間資料還是不能共用。像我現在住院，帶了平板，在家用桌機，出門用iPhone，同一個帳號設備間能互用，才可以想到什麼打什麼，不是嗎？
二、所選用的字型毫無美感，又無法取用其他字型，不是要大家留下美好的回憶嗎？一開頁看到沒有自己喜歡的字型，興緻馬上少一半

以上改了值四五顆星沒問題

### 4/5 — 検索文字列の検索記事(メモ)内のマーキング表示に関する要望

*2024-03-27*

タイムラインをタップし画面上部に検索文字列を入力すると、今まで入力してきたメモ(今は夢日記用に使ってます)群から検索して、その文字が使われてるメモを1記事づつリスト一覧で見せてくれてますが、そこから1記事をタップして参照モード(編集モードの1つ手前の非入力モード)で開いた際、その記事内で使われてる『検索文字列』をマーキングして表示させられるとすぐに探していた文の部分に到達できるので、そういう機能って追加できるでしょうか？ また記事を参照モードで開いてる時でも、文字列ができると便利かもと思いました。(1記事が長文だと便利)

**Developer response:** レビューありがとうございます。
ご要望について検討致します。
