### 3/5 — Clicking into a day is broken; refunded

*2026-08-04, version 3.0.5*

The app chiefly does what it says on the tin, although there’s no way i can see to manage which calendars the app displays - but if sharing what your phone has access to works with your setup you should be great! 
But, i immediately encountered a bug where when i click on a week, it pops up the *prior* week I had clicked on, so if I click the week of the 10th and the week of the 17th, the second click shows the 10th. The third click shows the 17th regardless of what i click, and so on. 
Since it also appears you can only click a week, not a day, this doesn’t really make the cut for me.

### 5/5 — SEE THE WHOLE MONTH WITH ONE TAP!!

*2026-04-22, version 2.5.0*

This is such a great alternative to Apple’s watchOS calendar because I don’t have to dig through so many pages to look at “full month view”, that is a top priority for me!!! 
My only slight critique is I wish there were more complication options.

Thank you for integrating my Apple calendar with this much more useful apple watch calendar!!

### 1/5 — Funktioniert nach Bezahlung nicht

*2025-04-11, version 2.5.0*

Die App funktioniert nicht. Bezahlt und keine Verbindung zur Apple Watch

### 1/5 — 使用開始する前から怖い

*2024-09-21, version 2.5.0*

電話と連携しないと使えないだの、実際にお試し的に使おうとしても「ロックを解除」となり課金させようと必死さが伝わってきて怪しさ満載。日本語の表現も変だし、流石にやめた方がいい。レビューの星が4以上なのも、ね。

### 4/5 — あと、もう一つで完璧

*2024-06-30, version 2.5.0*

コンプリケーションでカレンダー表示できるようにしてくれたら完璧です。色で日々のイベントを把握できるカレンダーは最高なのですが、コンプリケーションに表示出来ないのが残念で悔やまれる。

### 1/5 — Waste of time

*2024-06-25, version 2.5.0*

Nothing works, requesting money back

### 1/5 — Very Bad

*2024-06-02, version 2.5.0*

The app is not showing any Calendar details on my Apple watch Ultra 2. Just waste of money. I need the refund

### 4/5 — 文字盤での表示がアプリ名になってしまう

*2024-04-06, version 2.5.0*

月カレンダーを探してて良いのを見つけたと思いました。
文字盤の左上に配置したのですが、日付が表示されず、just ca…という形でアプリ名が表示されています。
この改善方法があれば知りたいです。

### 1/5 — ナスカレを使っていると使い物にならない。

*2023-09-05, version 2.5.0*

ナスカレを使っていて、そこから外部iPhoneのカレンダーと共有し、そこからこのアプリと共有という形になるみたいなのだけど、約束のある日だけを表示したかったのに、毎日何色かの印がついていて、その印に同じシフトが何個も表示されてしまう。その中に肝心の約束が埋もれてしまう。
全く、使いづらい。
課金したけれど、削除します。

### 2/5 — Requesting Bug Fix

*2023-03-06, version 2.5.0*

I paid four dollars for the full functionality. The complication does not show the next event based on the current time and the scheduled time of the event. It just randomly displays the first event of the day. This does not work well for a watch that is designed to help you with task planning.
