### 4/5 — あ

*2026-03-04*

書き込んだ文字のデフォルトの色が灰色だけど、黒にならないんですかね。もう見づらくてしょうがない、毎回黒に変更するんだけど、煩わしいです

### 2/5 — Update

*2026-01-21*

Since phone update I have lost all events 
Tried support but all in Chinese 🤷‍♂️

### 2/5 — 最近おかしい

*2025-04-25*

チェック✅が消えたり最近おかしい。対応お願いします。

### 5/5 — 他にこの見やすさのアプリはない

*2025-04-15*

なので、更新されず不具合が出ててもUIが少しおかしくなっててもそれでも他のアプリと比べものにならない使いやすさなので使い続けます。
出来ればAndroidでもリリースお願いします。
Androidにこのレベルで使いやすいカレンダーアプリが無いので……

### 1/5 — 突然消えた

*2024-01-17*

osを17にアプロしたら全部消えた。そして新たに書き込みも出来ない。

### 3/5 — osをアップデートしたらきえました。

*2023-11-14*

ios17をアップデートしたらすべてきえました。

### 1/5 — とても気に入っていましたが…

*2023-10-03*

突然、全ての予定の文字色が黒に…
色分けが重要だったのに…

### 4/5 — Update - Really love this app! Use it daily!

*2023-09-21*

9-21-23 Update. Whenever I travel, the calendar colors revert to black. I’m on the road for business, so this is a big issue. While I love everything else, this may make me switch to another calendar app, and that makes me very sad. I’ve used this one since 2011, but it might be time to move on. I’ll see if this continues.

Recently updated and still my favorite! I've tried others and keep coming back! This app keeps getting better with updates. Badge for date. I like the double-tap to expand the list, and ability to go to "today" by tapping the top bar on the screen. Unlike some apps, I was not prompted to review it, but I feel it's only right since I use it every day. This is my go-to calendar. Daily - I love that it shows my full entry, not part of it and then dots. Monthly - I like the look - seeing the full month and part of the tasks. I also really like that it syncs with both the iPhone calendar and Google, Although I am no longer using a google calendar, I did when I first bought this app. Search function, multiple calendars, including sync with the native iPhone calendar. **Please don't get this app only for the wallpaper function. It isn't an active wallpaper, but that is NOT the primary purpose of a calendar. ** Customer support has been very responsive - even when it was "operator error". Where some developers slide, these guys have kept this calendar up to date with all OS updates. My CRM app - Contacts Journal - to-do's sync here so it's truly all-in-one for me. If the nay-Sayers don't like this app, I would really love to know what they are using that's better.

### 5/5 — Beste Kalender ever

*2023-09-19*

Habe alle Kalender ausprobiert. Das ist der übersichtlichste Kalender den es gibt.

### 4/5 — 最近変更できず

*2023-05-21*

使いやすく見やすいので長く使用していますが、最近時間の修正が出来なくなっています。なので何度か時間に間に合わず困ってます
