### 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.

### 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。

### 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。

### 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.

### 3/5 — 2023年カレンダー開きません

*2022-10-09, version 2.5.0*

完全版ですが、2023年のカレンダーが表示されません。

### 4/5 — Why no 24 hour time display?

*2022-07-01, version 2.5.0*

When I first discovered this alternative to the native Apple Watch calendar I thought “this sounds a bit more like what I want a calendar to look like on my wrist…”. But after a couple of months I’m wandering back to my default Apple Watch calendar again - and the simple reason is I don’t like seeing 9 a.m. and 9 p.m. presented the same way. With this app 9 in the morning and 9 in the evening show as simply the digit 9, but the default Apple Watch calendar switches between 9 (a.m.) to 21 (p.m.) which I personally prefer! Why isn’t there the option to choose the 24 hour format if that time format is what I like to use? I’ve bought the full feature package of this otherwise very good app but please will you add a 24 hour time option in an update ASAP.

### 1/5 — A BAIT AND SWITCH!

*2022-04-14, version 2.5.0*

I purchased calendar events and then when I tried to open it, it gave me just a calendar. I tried going to events and it said my phone was locked. Tried fixing that and now it was asking me for more money to unlock a feature I purchased! I will delete this! Miriam

### 3/5 — Sync

*2022-03-30, version 2.5.0*

I really love everything about the app except it won’t copy the calendars app, I have holidays turned off but it is still applying them. I am using an i cloud account and the holidays are not included on there either. If I could get some help that would increase my review!

### 4/5 — Good calendar app for watch

*2022-03-13, version 2.5.0*

I was looking for a calendar app that displayed the large complication how I wanted it, this seems to be the closest to what I was looking for so far. It shows all day events and if there’s more than one makes you aware of the fact. It seems to sync well and quickly with my calendar. Also when you open the app the month view looks good and you can scroll through the entire year rather than just seeing the current month. You can also scroll through a long list of upcoming events. 
One thing I’ve noticed so far that I think would be good to add would be if there’s no current events maybe after a certain time the large complication could show tomorrows events? As far as I can tell it doesn’t do that and I think at least having the option for something like this would be good.

### 2/5 — 大丈夫？

*2022-02-27, version 2.4.3*

翻訳が無茶苦茶。
プライバシーが心配。

### 1/5 — Does not have even ONE sample

*2022-02-03, version 2.4.3*

This app is deceiving because EVERY feature requires a purchase.  It does NOT include EVEN ONE example that could be loaded to the watch to determine how well it worked or looked.  I deleted the app immediately.

### 1/5 — 課金したが機能ロックの解除がされない

*2021-11-29, version 2.4.3*

よくある質問に記載されていた通りにやってみたけど、ダメ。以前にも同様のレビューされている方がいるけど、解決されたのだろうか？

### 4/5 — Apple Watchではこれを使うべき

*2021-10-15, version 2.4.3*

Apple純正カレンダーから乗り換えるのに十分な機能を持ってます。
と言っても今月以外のカレンダーが見られるという一点があればそう言えるんですが。
カレンダーは先月、来月とかだけじゃなく来年再来年、数年前とかも見られます。そのあたりの閲覧機能は有料ですが。
予定などは純正カレンダーに書いたことがそのまま見られるので、iPhoneでは純正カレンダー、Apple Watchではこれと使い分けもできます。

ただひとつ、大したことでは無いのですが、文字盤にウィジェット表示した際のデザインの解像度が妙に小さくてジャギーが目立ってるのがいただけません。

### 1/5 — Kein Support erreichbar

*2021-09-30, version 2.4.3*

Negativ: 
Trotz Kauf der Vollversion, ist die Datumskompliktion nicht aktivierbar.? 

Ich wünschte mir eine Anzeige der Kalenderwochen. 

Versuch den Support zu erreichen klappt nicht. 
Ich hoffe auf Hilfe. 

Positiv: 
Die Anzeige nach Monaten ist gut gelöst. Original Apple Kalender-App auf der Watch zeigt maximal den laufenden Monat. 
Die App schafft Abhilfe, wenn Sie denn einwandfrei funktionieren sollte.

### 2/5 — アプリが開きません

*2021-08-11, version 2.4.3*

昨日フルロック解除で購入しましたが、アプリが開きません。課金はされ、アップルから領収書も届いてます。右上のランプが赤になっており、切断されましたと出てます。
どうしたら良いのでしょうか？
この状況をお知らせしたくメルアドをタップしましたが開きません。返信宜しくお願い致します。

### 2/5 — 결제했는데 안돼요

*2021-07-26, version 2.4.3*

모두되는 걸로 유료결제했는데 애플워치에서 언락만 뜨네요 버그인가요..

### 2/5 — Major bug

*2021-04-06, version 2.4.3*

I paid for this app and immediately noticed that my schedule complication never updates. It only shows what is next when I first add it and then stays that way for weeks. I emailed the developers about it within a few days of paying for it and I never heard anything about it. This is the main reason I only gave it two stars. 

There are however, many things I like about this app verses the stock calendar app! I like how I can scroll through the months, instead of only seeing the current month with icalendar. I also love how it includes the various colors that I use in my calendar, which helps me keep work from my private business from my manage events from my personal life. Not only that but it shows those colors in the month views so I don’t have to click on that day to see if I have something going on. 

I would use this as my go to watch calendar, and really want to, but the complication doesn’t work and I need it to. If they get this fixed then I’ll rate it better but the fact that my email was ignored and months have gone by and it’s still not fixed really doesn’t sit well with me, especially since I paid for that specific feature. This has been mentioned in other reviews with the developers responding saying they will fix it with the next update but that was dated back in August, so eight months ago. Seems like the developers don’t care and just want their money!

### 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。

### 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

### 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。

### 1/5 — はぁ？！

*2023-02-10, version 2.5.0*

全く使えなかったので
即
削除！！

### 1/5 — Good Application but......

*2023-02-09, version 2.5.0*

Application works ok but syncs to US Calendar not able to select or deselect a calendar. Application support link is not working. Perhaps it’s not supported anymore.
Uninstalled this application and installed a different one.

### 1/5 — Does. Not connect

*2023-01-02, version 2.5.0*

After multiple tries I cannot connect the app. When I tried to reach out to developer, it sends me to a disabled page.

App is connected and working as described.
I’d like to change rating to 5 stars.

### 1/5 — Watch Date Compilation not working

*2022-08-15, version 2.5.0*

I bought the full package but still can’t get the date on my watch face. Nothing works.

### 1/5 — Waste of energy downloading

*2022-06-09, version 2.5.0*

Downloaded app for free from “AppAdvice” with promise of free “date complication unlock”.  Big woop. That allows you to change colors. If you want to open a day on the calendar or see an event, forget it. You must pay for that feature. So basically you get what you pay for. Zippo. Ziltch. Nadda. Nothing! Delete.

### 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!!

### 5/5 — Very nice.

*2022-01-24, version 2.4.3*

This app is much more powerful than the Apple calendar app.  It shows the next upcoming event, as Apple's does, but then tapping on it provides the next events very compactly and conveniently.  And it also provides the next three months as Apple's computer calendar app does, even getting the colors of multiple calendars correct.  And it even remembers which view you used last time.  It's awesome.

it has only two minor bugs that I've noticed.
1) When there are three or more events today, it shows the first one correctly, but then, below it, it says "2 more event", which should be "2 more events".  The Apple watch is so elegant that even a minor grammattical error like that is somewhat irritating. This app does everything esle so well that this should be fixed.
2) In three-month view, when you scroll down and click on the down-arrow to show three additional months, it repeats the third month.  2022 has only one March, not two...

These should be easy fixes, and they're minor, so don't avoid buying this app over them.  The $3.99 price for the full app is more than reasonable.

### 5/5 — 代表的なアプリには無い機能

*2021-07-21, version 2.4.3*

カレンダー&タスク管理アプリは色々と触ってみましたが、代表的なアプリはその日や良くても次の週までの予定しか見る事が出来ず、月毎の予定を確認したい時にもどかしい思いをしてたので、このアプリを見つけた時は感動しました笑
iPhoneの純正カレンダーと連携しており、月毎どころか年間のスケジュールをこのアプリ単体でApple Watchから確認出来ます。まさに自分が欲してた機能でした。おそらくこれからどんどん流行っていくと思います。
確認する分には最高のアプリなのですが、1つだけ追加して欲しい機能があり、終わったタスクをこのアプリから直接消去出来る様にしてほしいです。現在終了したタスクを別のアプリで消去&追加してるので少し手間です。音声入力によるタスク追加等は別のアプリで完結させていこうと考えている為、このアプリ単体でタスクの消去だけでも行えるようにして欲しいです

### 5/5 — Edited: now it works great

*2020-12-05, version 2.4.3*

Go buy it, be a bit patient for the complexion in the watch, but it works and we see the coming days on the watch! Thank you.

### 5/5 — これしかない

*2020-11-19, version 2.4.3*

スケジュールと月間カレンダーの表示ができるので、便利。単純だけどこのアプリしかない。バグ直してがんばってほしい！

11/19 追記
色々改善された？クロノグラフの隅とか見られるように！助かる！

### 5/5 — 구매했는데

*2020-09-13, version 2.3.6*

This app is simply great!!

### 5/5 — So far GREAT

*2020-08-25, version 2.3.4*

I use my calendar all the time and so far no complaints about this app, I love the fact that I can see more than one month now. Great app, well worth the price.

### 5/5 — Simply great

*2020-08-17, version 2.3.3*

Make this date feature on your watch like calendar app on phone so amazing
