### 5/5 — 使いやすいです！

*2026-06-17*

シンプルで使いやすいです。
先延ばし癖と忘れっぽさから完璧なスケジュールを立てても上手く実行できずなぁなぁに過ごしていましたが、こちらを使い始めてから改善されました。
スケジュールの通知を入れておけば1日の作業にメリハリもついていい感じです。

### 5/5 — いいと思う！

*2025-12-19*

色々使ってみた、これ系のアプリの中では今のところ1番使いやすい！
あとはスケジュールを削除できるようになれば完璧

### 4/5 — 削除機能希望！

*2025-11-19*

単純に見やすい、扱いやすい。ただ、一度設定した予定を削除できない？

### 5/5 — やっぱりここに戻ってきました

*2025-03-13*

別のアプリを使い始めたのですが、私にはやっぱりコレでした。
戻ってきた理由は、見やすさ（表示が大きめ）と使いやすさです。

・一日の予定がおおまかに把握できる
・タップすると詳細が大きな文字で見られる。
・繰り返しの予定が一覧で出て、すぐ入力できる
・以前の予定が見渡せて、その中の1日を全部一気にコピペできる
・通知もちゃんと来る

操作も画面もシンプルなので、やっぱり見やすく使いやすい。
ありがとうございます。

### 5/5 — ウィジェット希望

*2024-08-23*

類似アプリの中でも最も過不足なく使いやすい相棒です。どうかウィジェット対応を！

### 5/5 — This is the one I needed.

*2024-07-24*

I love this app, thank you for making it. I would like to see a future update that includes an overview of monthly or yearly charts but seeing as it hasn’t been updated in a while, I doubt it will happen… well, maybe I can use this app as an inspiration to learn how to code and develop a worthy successor to it. Thank you for creating this.

### 4/5 — 基本的に使いやすい

*2024-05-02*

シンプルで細かいスケジュールを円グラフで見ることが出来るので空き時間の把握等とても可視化され、カレンダーも月表示なので見やすいです。
ウィジェットや他のカレンダーとの同期などもあればな...と思いますがいかんせん更新がずっと止まってしまってるようなので改善は望めないのかもですが。。。

### 5/5 — とても使い易いです！！

*2022-06-25*

長期休み時の１日のスケジュールを把握したいのでアプリを探していましたが、こちらは予定も隙間時間も分かり、使い易いです！

今後改善して下さると嬉しいと思う点は、

・円グラフの時間を6時間毎ではなく、3時間毎にして欲しいです。何となくの予定が分かれば良いので、今のままでもいいですが、やはり9:00、15:00、21:00があるともっと見易くなりそうです。

・予定の文字が長いと、円グラフの時に隠れてしまったり、短い時間の時は隣の予定と重なってしまうので、字の大きさを変えられると嬉しいです。

・円グラフをクリックすると、予定が下に一覧で表示されますが、もう少し小さい文字でもいいかと思います。また、円グラフの対応する色をつけてくれると分かりやすいです。

とても良いアプリですので、もっと使い易くなる事を期待しています！！

### 3/5 — Recurring plans?

*2021-04-14, version 2.5*

It is unclear what the “schedule limitation” mentioned in the IAP info means. It is important to be able to extend a plan over multiple days/months/etc. Also, the plan view should graphically indicate the time of the day on the circular map, and Help/FAQ should be in English in the EN version. I am not going to make an IAP without knowing what I get for CAD $3.99

### 1/5 — アップデートしたら起動しなくなった

*2020-11-09*

iOS14.2にアップデートしたらアプリ起動しなくなりました。
