### 5/5 — Simple clean and fit for purpose

*2026-08-14*

Easy simple features that gets the job done.

### 5/5 — めちゃいい！

*2026-07-13*

時間に通知して知らせてくれるし写真も載せて、パスワードあるからプライバシーも守れるし未来過去全部出来るから忘れた日も書けるし未来に書いてメモ代わりにしてるw

### 5/5 — 使いやすい

*2026-06-16*

半年ほど使った感想、とても使いやすいです。本当にシンプルな日記なので操作等も分かりやすく、大変愛用してます。
画像も貼れる、日付変更可能、パスワードも付けれます。結構ガチで有能なアプリです。設定からパスワード変更やライトモードかダークモード、本体設定通りかが選べます。記入時間のお知らせ(通知設定)もできますし、今のところ不便に思ったことはないです。(ガチで)

本当におすすめです！！

### 2/5 — Best thing about it - it’s free.

*2026-05-13*

Two stars because it’s free.  Zero functions.  Most annoying is I can’t change the date format, which is the nonsensical American way.

### 5/5 — Great diary easy to use

*2026-04-28*

Simple but effective

### 5/5 — Outstanding!!

*2026-04-12, version 2.0.7*

What a joy to find something so easy and simple to use! An inspired idea, and perfect for the job, love it!

### 5/5 — 唯一続けられてる日記アプリ

*2026-02-21*

これまでに、何度も何度も日記を書こうと思っては、紙やアプリやらを試してきましたが、三日坊主どころか、一日坊主しか続かなかった私が半月以上も続いてる唯一の日記アプリです。

とにかく、デザインと操作性がシンプルで、日記を書くことに特化されたUIが最高です。

他の方のレビューを見て、「気がつくと日記がいつの間にか消えてる」みたいな意見がちらほらあって、使い続けることに不安があり、他のアプリでいいものがないか、一通りダウンロードして触ってみましたが、このアプリ以上に、好きなUIで、ついつい書いてしまう日記はなく...その辺りのバグ？は解消されてることを願って使い続けることにしました。(今のところそのバグは起きていません。改善されてるのかも？)

いくつか、こうだったらいいなと思うものを...
・日記の検索機能に、日付指定での検索機能を追加する。
・日記を編集する際、右上のアイコンから編集を押さなければいけないので、ダブルタップなどですぐ編集できるようにする。
・画面下部の◀︎▶︎ではなく、スワイプで前後の日記を表示できるようにする。
・自動バックアップ機能&クラウド連携で、pcなどからも同時操作可能に。
・日記をPDF出力して、紙印刷でも残せるように。
・写真を文の途中挿入できるように。
・リンクを貼り付けられるように。

どうぞよろしくお願いします！

### 5/5 — Simple efficiency

*2026-02-09*

I love how bare bones this app is! It's great for quickly jotting down thoughts when I'm in a hurry. I simply tap on the app and begin writing. There's no navigating through other files or sections first. I also love how it automatically dates my entries. As a writer with ADHD, the simplicity of this app allows me to quickly and easily jot down the many ideas I get when I'm doing other things. I highly recommend this app for those who crave simplicity and want the conveniences of technology without the complications that usually come with using it.

### 4/5 — 字体大小无法调节

### 5/5 — The only journal app I’ve liked

*2025-11-26*

Over the years, I have tried many free Journal apps, and a lot of journaling apps that give you a free trial before wanting to charge you boatloads of money for a subscription… none of which I ended up liking or using for very long. This has been the best Journaling app I’ve found, I have minor adhd, and the lack of distractions in the journaling process of the app has been a game changer. A lot of the other apps out there boast features of changing text or background color, font sizes, adding stickers, linking things like planners, etc. But as someone who wanted a simple daily documentation experience, this app really hit home. The entries are simply listed by the date written, and there’s a calendar view, so I could click on last Tuesday on the calendar and bring up the entry for it. There is a journal lock option which I think is a nice feature, albeit not one I require. If you’re looking for a simple, yet visually pleasing way to blurb your daily thoughts, look no further.
